cobalt327 Not all posts to old threads are a bad thing, but in this case it's a waste of time and space IMHO.

There used to be a line of red font text that popped up if someone were to try to post to an old thread. Can it be reinstated?

They should make good torque in the lower rpm range, up to the torque peak anyway. This is not necessarily a bad thing if you are wanting a good stout street motor. At some point in the upper range of rpm's, the intake ports will stall and the motor will nose over. Most of those double hump heads are around 165cc's intake runner volume, while you need somewhere around 200cc or a little larger runners to support a 383 to 6000. If you're going to limit revs to under 5000, then the humps will work fine. It won't be a race motor, but it will make good low end torque to pull a heavy car around town.

camaro355 yeah the intake runners on the camel humps heads just arent big enough to support a stroker but they do make a really good street head

killerformula yeah forgive me if you thought I was knocking hump heads, but I think you're making the same point I was. I don't think you're going to be in the 400 horse range with them, that's all I meant.

Cstraub With these parts you can make that kind of power, but
the camshaft to make it all happen would not be a good
streetable piece. I would suggest getting a set of 200 cc
heads with 2.05" valves. These heads are large enough
and flow enough air at low lift to use a mild camshaft.
This would get you to your goal much more cost effective.

BT74 RE: camel hump heads. In the mid 60's some of the 461/462 FI heads did come with 202 intakes. The casting # was the same as 194's. Alternatly, lots of shops would grinds a set of 194's to accept 202's.

You obviously dont know WTF you are talking about. The crank is not turned down .400. If you are going to give advice, at least do some homework first. I could tell you what the numbers are, but it would be a good excercise to find out yourself.

The stock parts should be fine on the 425 HP range engine. I would also not just toss the double hump heads. They make great torque and are killer street heads. I have a set that are pocket ported and gasket matched on my 400 SBC. I run a pretty fat cam to help make up for the flow on the heads, and it is a very respectable engine. I have never dynoed it, but I would put it in the 375 HP range or maybe a little more.

troy-curt rifraf, I can't even make sense out of your posts. If you know so much, why are you asking these questions?

You guys are on the verge of being trolled.

Robinson Robin The small blocks chevs and very strong bottom ends even in 2 bolt main form, a cast crank and a set of reconditioned rods with high quality rod bolts could easily survive making 425. That seems to be a mistake alot of people make. they spend way to much money on after market high priced pieces when its the necisiarry and sometimes won't even life as long as stock pieces will.Don't ever under estimate stock parts

killerformula ?? No, I think you're too skeptical about stock parts. Hers's proof of my claim, scroll down to the section about rods-

killerformula I think I'd have to disagree. Sure stroker motors aren't the best rappers, but if you ballance a motor (which you must do with a stroker) you can push 55-6000. I also am positive you can make well into the 400 horse range with a stroker, you just need decent heads and a good cam. You can even use a stock botom end up to 500 HP no problem. Stick with a duel plane intake and you're cool. You don't need a fat pocket book. That's the reason 383's are so popular, they make great power and they're cheap.

rifraf Yea,10 and above your pushin it and ya better know whats up after that,383 motors build great torque but don't spin well unless your wallet is fat. I would run 10 or less with a cold thermostat ,curve the distributor,cold plugs,and either settle for 375 with big torque or build something else , unless your loaded. Still not enough info.Sorry.
