I often read that the strength couldn't be beat when it came to a shaft style compared to pedestal. I know as far as changing out or tweaking that a pedestal wins out for ease and speed. But I'm not the guy who'd know for sure, and maybe most of the stuff I was reading was 20 years ago, or...

My bad,,,didn't look at the photo. That bar running across under the rocker shafts looks beefy. What about the stainless steel part? A lot heavier then aluminum, of course it's stronger, but is this just for extreme spring pressures? Like when you start running a 7/16" push rod :O ? How much...

Although the design isn't perfect, Nothing stronger then shaft mounting, seems like a step backwards to go to pedestal? And stainless steel, why? Please clue me in as to why I would want that? I have T&D on my Indy 360s, likely I would be happy to do the same on these heads. But I'm open to be...

I've only taken it down the track twice, running the 28x13.5s and the 3.55s out back (**** combo). I have a set of 4.30s, but need another 489 case etc. Anyway with horrible launch and best 60' of 1.74 the best 1/8 was 7.307 @ 98.4mph. The best 1/4 was 11.31 and best 1/4 mph was 128.9. Also my...

It sure is!!

If that was directed towards me,,,all info is in my build thread. Theres a video on last page. I run either 345/30 18s or 28x13.5 15" ET Streets.

I've got 2500 miles on my 605hp 416 (340). I bag the crap out of it. Its a street car, no fill in the block. Machinist told me its the best 340 he's ever seen for minimal coreshift and thickness of cylinder walls. Its a '73 block. I am running billet main caps and stud girdle. I think up to...

I have the Hughes rockers on My Eddie headed 340 in my truck, work great. Good quality. I have T&D on my Indy headed stroker in the Demon, awesome quality but cha-ching $$$

605HP here with 416....like mentioned already, you need a great mix of top end components. Lots of potential for horse power in those 408, 416, or 426 air pumps, but you need a premium top end and a good cam to move that air/fuel mixture. You've obviously not been behind the wheel of 600hp...

Because talking about a 408 or 416 is such a stretch to a 426......but thanks for taking the time to post your useful comment. Good for you ;)

Most people building strokers aren't likely to get 20000 miles on them before rebuilding for performance or out of boredom. I doubt I'll get to 10000 before I rebuild my 416. I only have 3000 miles in last 3 years, doubt I can manage to go 6/7 more years before I'm bored and want to make some...

I just pulled valve covers off and dizzy out. Slowly turned crank and used a drill with extension to spin the pump. You'll see when oil gets to top end on each side. ^^^^ treed me. Lol

Sure,,,I can live with that. :) Look above,,,you forgot number of cylinders too...lol.

But,,,he didn't say he went 4.250 himself. I'd suggest the whole formula when showing math, in case newbies were trying to figure out how you got those answers. Pi x radius squared x stroke, not everyone passed math class or cared too. Lol

Just read through your build thread for the first time,,,looks good! The dart is a beauty, you are going to enjoy that ride of yours once it's running:) Will be good for 25 smiles per gallon, at least!

I run an 850 mighty Demon on my 600hp stoker, works awesome. And a 750 mighty Demon on my 340 in my Fargo, still dial in it in but works real good. These were new in box from the Barry Grant era.

I bushed my lifter bores on my stroker because it's solid roller, for 2 reasons, strengthening the bore the the lifter travels in and oil control. Wouldn't recommend it for anything with hydraulic lifters since oil supply would be to low to pump up lifter, I'm guessing, since The bushings used...

On a factory small block LA dodge it sure does. Oil goes from galley, down to mains and up to cam and out to heads (rocker shafts). On a factory LA oiling system the last part to see oil is the rockers. I did drill out the passages to 5/16" from the galley to the mains, and several other mods to...

You shouldn't have to, not to say that doing some mods wouldn't be beneficial. Read the sticky at the top of the smallblock forum, lots of great ideas. I applied most to my stroker. The tapping into the main galley and providing oil crossover to the valve train with out having it first travel...

Fact - fluids aren't compressible. But I get what you're saying :P

Ok,,,I see now what they mean by high pressure pump,,it's regarding the bypass. Cool, learn something new everyday :)

Like mentioned,,,it's all about clearances. High volume will equal high pressure with tight clearances. It's impossible not too. I'm not even sure if anyone sells a pump that's "high pressure". Pumps are based on volume,,,and what you pump through will dictate pressure. On my stroker I run a...

I'm late to this party but I agree with some that you should stick with flat tappet,,,or go full solid roller. No sense wasting money on parts that don't equal performance gains that would be noticeable.

Runs great on the AV Gas, no issues. And I was buying it at the airport for 1.50-1.75 litre last couple years, so it's not a lot more then premium as of late. Not sure what price of AV gas is now. I still have a full drum to burn up before I find out.

Thanks for the additional info and options fellas.

Good to know. I may have to experiment a bit. This motor run 180deg all day long until you get over 90 outside. Then stop n go will bring it up closer to 200. But hiway it stays cool too 100deg ambient no prob.

New forum sucks on phone. Oops Anyway. No to iron heads, Indy 360-2. Why? Cause I was thinking of cruising further without needing to pack fuel. This is a street car, power everything but no a/c. It's 600hp, so like I said no biggee if I lose power. I know I could pull off pump gas with 11:1...

Good day, I know I will lose abunch of power but could I take enough timing out to run 12.2:1 compression on 91octane with no detonation? Currently for max power it's set at 34deg all in but I run 100LL AV gas or I mix 50/50 premium with race fuel. Thanks.

Never had issues with any MSD products I've run.
