It's all up to you! You have to look at everything on the car..will it hold up to the 408? What gearing? Car show? Really??

Car is mini tubbed with 325/50's. Narrowed Strange 60 with 3.55 gears/Eaton Truetrac, frame is tied, rebuilt 727 but may need some strengthening, new shaft with 1350 joints, disc brakes all around. I have been building this car with the intentions of making some power.

When I said car show, I mean going to them not showing the car.

Ha ha! I just had to give you a hard time. Sorry...LOL.

You will absolutely love the stroker on the street. Especially with the 3.55 gear. I don't know a single person that's went to a stroke sb that would rather have a 340 or 360 on the street.
 
Damn Brian, you had me going! I was wondering all day at work why you were questioning my build?!?! I thought I was clear in my PMs. I'll be in touch.
 
Brian
was wondering what you run for clearances between the stainless rocker arm sets when you set them up - i was told no less than .005" and no more than .010"

thanks

.010 to .012 is what we set them at.

I'm glad I got no stroker on the street. Rpm rules far as I care, nothing like a screaming engine--just like those M6 BMW with under a 3 inch stroke crank. 8,500 rpm those engine scream. Lightening fast take offs thanks to some type of traction computer control deal those cars have. Once moving thou, a hot 340 can hang with them--don't ask how i know.

I guess if I had an 8 inch converter over the 10 inch I got now and 4.56 gears vs 3.91's, it could take off from a dead stop as quick-if not quicker than an M6...true true, after 110, it be good bye M6, I think those cars are good for 150 or so..but its got OD, not fair !

That is the whole deal, RPM's. the 340 need rev's. Too many folks don't want to scream their engines out. People want 3.55 gears and then wounder why its not as quick. Car Life in 1970 posted that 4.10 gears are the best compromise on the street, that 4.56--4.88 are a little too much, lol.....guess that meant people were really running those short gears on the street but then Chevy's 327 with a 3.25 stroke was good for 8,000 rpm with a bit of prep.
 
That 340 better have some W-2 heads on it ported to the MAX and alot of compression to hang with a small block stroker. With my 410 4spd & 3.55 gears there was no way my buddy Cliffs car with a 340 4spd & 3.91 gears and ported x heads 10.5 compression, and that 340 is a super HOT 340 580 lift cam 250 ish @.050 on a 108 LSA alot of cylinder pressure,, sounds like a NASCAR engine at Idle and rev's to the moon. I would stomp him from a dead dig & at a roll both starting in 1st & 2nd gear and rolling 60 mph & up, I mean beat him real bad,. I don't agree with your Hot 340 hanging with a Stroker. A Small Block Stroker has EXPLOSIVE acceleration and grunt like no other.

And gas was 30 cents a gallon. Life is about making compromises. I ran 391's when I first got my Dart and couldn't stand the car on the highway. I could literally watch the gas gauge drop while the engine roared. No fun at all. I switched out the pumpkin to 323's and got better gas mileage and highway cruising, but lost the stop light fun factor. I think the 355's will be a good compromise, and the torque of the 408 will help get the car moving. JMHO
 
but the gas milage is still crap cause of the 4'' arm pulling the heavens from the sky...

Look at what a g stock 340 runs-10.90's, w/no after market heads, or roller cams or even more than .444 lift...lol

How many 'i know some do' but how many of you strokers can go run 10.90's right now?



Gotta remember ...theres a thing called rpm, it's how lil engines can beat bigger ones...ha ha
 
When do you worry about 10.9s in the street?

Thats like saying I'll take an F1 car over a NASCAR because it has a higher top end -

Strokers give you near or better in gear acceleration at practical street RPM..thats the point of a "streeter" ain't it?
 
I didn't realize this was a "theory 101 class" thread...? I thought it was about RHS heads on a 360.

Yes it was about RHS Heads on a 360.
But dude is saying a 340 would keep up with a Stroker on the Street, I had to chime in cause it ain't going to happen.

=strokers can make more torque 'built the same'

I agree, we all do... in fact.

Where some are differing in opinions ...is the whole ''no 340/360 can whoop a 408/4'' stoker sb''.

like remember the 440 vs hemi test?
The 440 whooped the 426 hemi same 3.91's gears......till they got some real gears '4.57'...then the hemi destroyed the 440.

you take one of our members 410's for example, we know what it makes,gears,heads,rpm it turns....now build the smaller motor around that.

remember nascar back in the day when there were big blocks AND small blocks running against each other? lol

Build it for this, build it for that....use this part or that part and do the same or better....none the less, back to the 360 dyno test

Brian - I've been about the "forums" for 13 years....this thread is "mild" as far as "Off Topic" goes. LOL!
Click to expand...

I agree! It is mild...so far. I hear what you guys are sayin' and totally understand the arguments. It's kinda funny that people argue over things that really are "personal preference".

Any engine in the right hands can be made to run great. I also agree for a STREET car with tall gears a stroker is a much better choice if you want that BB feel of power.

Kinda self explanatory really....LOL!

Yep, the "gearing" issue is one of those things that goes to the definition of "streetable".

As Brian says - its a matter of personal preference.

My only comment would be there's more likely more people who prefer 3.5's on the Hwy to 4.11s. LOL!

Brian another question; -

Hypothetical build : Lets say we have a Factory unported head (587 cast) 10:1 360 with a [email protected] / .520 lift cam, SP intake suitable ignition and carb...........

Which heads :

RHS 1.88 valve, or
Eddy

....will show more HP improvement straight out of the box - with NO work ?

Which out of the box RHS (assembled) head are you talking about? I believe IMM builds their heads from unassembled RHS castings. Are you talking about an assembled head directly from RHS? or companies like IMM that make their own packaged head assembly using RHS basic castings?

This is true. It depends on WHO'S RHS heads you compare. Our heads will hands down outpower the eddy heads OOTB on any engine build IMO.
 
Can't please everyone. I would put the dollars into quality before quantity on a smallblock.
