low compression

-
Maybe we should have some kinda low compression shotout. Now THAT might be fun. At least to me. I have two 318s I could use. A 88 roller block and a 77 model engine. I have a good recipie...and was gonna post it.....but I think I am gonna keep my secret. LOL
 
I tried this before. The "Go fast for on the cheap" thread and made note several times that it would be a contest that needed the contestants honesty, as in no cheating, just follow the basic rule/idea of it all, and everybody wanted rules, then the question came up, who's checking?

I also clearly stated several times that there would be no prize money or item. But the general public complained and demanded prize money (In several PM's)from me. Personnaly.As well as FABO.

I'd love a contest with this basic idea, but after getting over 50 PM's from people who clearly did not read and / or get the idea, well, I canned it. It was to fustrating to answer the same DUMB question(s) over and over again.

Yes! I fnnnnnalllly found a dumb question. It is the one where the answer is in the text you failed to read and complain about.
 
Sad people lose the idea of fun isn't it Rumble? Would be an awesome shootout with a few ground rules
 
I guessed I missed the point here, which is to hobble yourself by running a cheap piston, and then building around that handicap. Rather than building to take advantage of everything else. So, knowing this, I like the 440s for low compression. Long stroke and the best chance to make torque without having the compression more performance oriented. I'll be more than happy to design and build one, but I'm not paying for it...lol. It's no harder than anything else, the parts just have to work together, adn the whole car needs to be set up around that to get good numbers from it.
 
* I think* I kind of sort of repeated myself from the aforementioned thread in the above post I made. To repeat myself again, the basic idea for fun only and the basic rule package was;

no piston changes, no offset crank grinding, no head porting, but a rebuild was fine and personaly, I do not see a problem witrh the addition to a multi angle valve job while the heads being rebuilt.

In otherwords, the engine is dead bone stock with the allowable change of headers, intake, cam and distributor if so equiped with a lean burn, or worn out. Carb change is welcomed.

Gear ratio and leaf springs as well as a onverter and shift kit allowable.

Is that good enuff? If so for you, don't worry, somebody will put on a dress and ***** about something. No one can be happy with this basic set of rules.

then, sooner or later, some jackass will type, "Whats the incentive/prize money amount and whos checking? Where is it being held, etc......
 
Oh lookie here, prime example;

Answer, because some people simply do not have the money to do a full and total rebuild. Isn't that what the low compresion question is about Moper?

With this statment alone, you shove the person with no money into a corner and make fun of him as being a cripple and shouldnt bother trying to have fun and make power with his engine.

I guess, "Broke/low income guys should not apply/subscribe to adding extra power to there engines."

Is the new answer, "If ya can't afford to rebuild the MoPar, go run a cheap *** Chevy?"

Here comes the pissin matchs and whinnnnners everybody.
 
Real point of my initial post was to see if anyone had a good, low compression, pump gas, good HP combo. I think a "smog" shootout would be loads of fun in the future if no one cheated. Plus in my opinion it emphasizes budget build and makes you use your noggin on how to get the most outta a boat anchor :D
 
Well I have built my engine around the stock pistons, and crank. It's not the ideal engine you were looking for, and it's not that low on compression anymore. I took a 318, and cleaned up a pair of old 360 heads I had sittin in the back yard, milled em down to a 57~60cc combustion chamber, and put a thin head gasket on. Put a cam in it, intake, headers, and some third hand roller rockers I got for $40. From my little 318 I am making 368hp and 397tq. With some head porting I could get it to the 400's easy.
 
rumblefish im up for a 400 smogger low budget grudge match. i just did a 400 and put it in my duster in may. i already have a street strip car so that wasnt my goal. i wanted to have good torque pretty early. i honed it, new rod main and cam bearings, cast rings, i had a 383 steel crank balanced for it since im running it with a stick i didnt want that funky balanced flywheel, i used the old 906 heads off my dart that had quite a few passes and some street miles, years ago they were cut just to clean up and a good valve job i put them on with some mr gasket shim head gaskets, i would have ported them but i didnt want to hurt my low rpm torque. i baffled the pan, a used windage tray, and deburred the block, a small summit cam and summit roller chain, some used iron adjustable rockers and pushrods, used performer intake, used holley 750 3310, used 1 3/4 headers. it runs ok. it wont win a lot of races but it does do what i wanted. there are probably tons of cams out there that would be a better shoice for a street strip build, intakes too, there are plenty of better choices. i think the piss poor compression is hurting me more for my cruising than a street strip build. its definitely fun though.
 
Purt near all my engines have been like this. Precious few have I really gone all out on. This Hemi, for example, I don't know why....but I have been in the right place at the right time so many times it is pathetic concerning deals and parts. Hell, I bought the whole engine for 400 bucks, and I swear I couldda put batree and fire to it and it wouldda run.

The idea someone would insinuate a low compression budget build is like a handicap, is really insulting to me. I don't look at others builds on here that are way outta my league and scoff at them in jealousy. I think they are awesome. It is nice to see what someone can do without the financial limitations that I have. Also lots of times on those builds, I can pick up some ideas I can use elsewhere.

Rumblefish is right here. It is all about one thing. FUN. Rob, I think the "rules" are perfect, just as they were with the budget build idea that got canned. No complaints from me. So I guess all I got left is, if you are someone who cannot see the point, just hush up and let everybody who wants to have some fun participate.

Not at all. If they can afford a full on rebuild, they can afford the better performance oriented hyper pistons. I just looked on SUmmit racing. The factory non-valve relief pistons, with thier low compression are $336 a set. KY 237s are $339 a set. So the hobbling has nothing to do with cost, and everything to do with sensibility and taking advantage of what's out there. If you are calling a ring and bearing job, with no new pistons, no lower end machining, just a degrease and some new wearables a complete rebuild, you're way off base already. I threw together a bunch of these over the years. They ran good for me. In several cases, much better than the more pricey complete proper rebuilds. But generally not as good as a proper rebuild, and generally lasted long enough, but not thousands of miles. You do get what you pay for. My point is KNOW what you could pay for and use it to your advantage. Simply saying "run flat tops way in the hole" is not making use of what you have available for the same money.

The answer is stop being so thin skinned and do some research.:joker:

Edit - I mean you're off base to what is by definition a rebuild job. If you mean a re-ring or freshen up, then no valve job changes should be permitted. I thnk we need to call it a good running stock engine that is upgraded to whatever, with bolt on performance parts. That's really what you're talking about here and in the past, that's what I have built. I'd still take the 440 for the stroke, or 383 for the higher factory static and easier-to-deal-with smaller bore over the 400 but that's just me.

I'm not going to proclaim that I have a full understanding of what dude is talking about, but I get the feeling it goes something like this:

See what you can do with the stock shortblock limitations. Allow re-ring and bearing replacement so people aren't scraping through junkpiles trying to find a 40+ year old motor that runs well enough as-is to be worth using.

The idea of allowing the rebuild would not be to build a hot-rod motor, but to simulate a stock shortblock; an ultra low budget build. Because its Mopar, it would be low compression at that point. Again, if I understand correctly.

I can see the idea being fun, depending on what the other rules were like. If you get too restrictive on the rest of the car, well, its too much work to run 13s with a 440.

I personally find the $$$/fun ratio goes way way way down once you get into the machine shop jail (Two weeks! It'll be done in two weeks!!).

You could never run any kind of real competition like that though. One competitive guy will ruin the whole thing. Acid ported heads, NASA valvetrain...you know...stock eliminator.

HERE'S MY COOL IDEA:

The best way to do it would be to get a side forum together and get a bunch of guys together with similar interests and an understanding that its supposed to be fun. Rules are posted. Users optionally detail their builds in that forum with photos, and periodically people report back from the dyno or the track. Other users are more likely to believe said claims if they've seen the photos of what is in the build.

Maybe you get the LUNKheads (Low or UNKnown compression) together at Bowling Green once a year just for the hell of it.

IF there had to be heads-up racing and $$$ prizes involved (who the hell would sponsor this?) you'd have to do a teardown to claim the prize. Not maybe, not "if certain ET limits were exceeded". If you want the trophy, the bragging rights, and the adulation of tens of middle-aged men, you pull it apart at the track, no ifs ands or buts.

The guys that were in the group would really enjoy it, everyone else would wonder what the hell was the matter with them. haha.
 
Of course I think tis a good idea, that's what i've been doing with my magnum from day one. :)

Do a little work, post it on the internet. I've actually PMd and emailed with some pretty cool people after posting about a particular milestone or problem.

It makes my high 11 second timeslips some of the most satisfying I've ever gotten, and I know my wallet is happier.

Hey Moper, firstthing I gotta say to you is;

Sorry. I came off F%^& up and cranky. No offense to you personnaly. My humble appologies.

Second, ya, lets start with a dead stock engine and leave the short block as deliever from the factory. Heads as well.

However I do understand that the heads may very well need to be rebuilt. IF one should want to do just the heads - with consideration that the short block is in good shape - then that would be fine to do.

Now if a short block needed to be rebuilt, then new higher compresion piston would be the right way to go about it. Not replacment slugs that allow an echo in the cylinder.
 
LX. I wouldn't go rebuilding an engine with low compresion slugs to compete in this freindly afair. Or ask anybody to do it. One, I just don't havethe money to do so. I do however have a low compresion 400 in a Duster that I can screw with. When that engine gives out, IDk just what I'll do with it. 472? 500? (I'm skipping right over the 451 idea, thats for sure.)

Lunkheads, LOL! Like the name!

I suggest that if anyone wanted to try it, have at it and have fun while doing it.
 
i have the same plan rumble, run it till its pretty tired and smoky. i too figured skip the 451, but i found a crank for a good price already machined, so i might do that down the road.

I have a 383, Eddy heads runs on 91 no problem..likes 110 as well...
On the dyno it hit 499 HP..

that 499 would drive me nuts. I would of had to do something to get that extra 1 hp lol

Rob, that sounds good. And the cylinder head thing....you had said something earlier about a multi angle valve job. Well, most people don't realize it, but a stock engine has a three angle valve job already. I'm just gonna sit back and watch this unfold. Hopefully it'll materialize this time.
 
Rob, the cylinder head tihng may be a must for some. It's in-expensive enuff to allow under the table. But a whole engine rebuild? Naaaaaaaa.

Right.....I was kinda thinkin more of an overhaul. Rings, bearings, oil pump. How bout timing chain? Any restrictions there? Or cam timing? I HAVE an original 77 318 that would probably run.....but freshening it up would be nice.
 
Don't ask me. I aint going down this road again.

Think! If your overhauling it, then why not HI comp slugs? It aint cheap anymore.

I'm out of this convo.
