looks like im probably be keeping my conv challenger thru the winter at least so im going to be changing a few things in pursuit of more power of course. first question is whats the biggest cam you can run in a 5.7 with a stock piston ? how do you tell what year of motor you have?

The PWR stage 3 comes in at .604 lift and 234 @.50 duration.

Hate to think how close the intake valve is...but the lsa is pretty wide so that helps.

Seems to make good power - especially above 4500.,,,,but thats a tell-tale sign that the ICL is probably retarded to allow it to work at all.

I had a good friend call me last night. And offer to sell me everything he had for a gen 3 deal he was putting together to run a 275 class locally. But decided to go another direction because of rocker arm prices. His heads flow great or at least I think they do they flow 385 on the intake have new bigger valves I can get them and everything else just doesn't have a crank rods or pistons for 1000 thinking about getting that an do another motor completely an just put this one to the side or sell it mine has 32000 miles on it.

I'd like to see pics on the heads.

I wouldn't run more than a 219/223 on a 114 for a stock motor with boost.

the heads have been on two flow benches one of them being a well known rocker arm company that confirmed the numbers said they were the best set they had seen

Here it is in a nutshell:

Early style

03-08 Truck 5.7
05-08 Car 5.7
06-09 Car 6.1

Late (Eagle and apache)

09+ Car 5.7
09+ Truck 5.7
10+ Car 6.4
10+ Truck 6.4

You can't swap the timing covers between early and late (not that I know..)

You need to center your build around the timing cover. If you want a 6.4 then you need to source all the accessories for that. The biggest degree of interchangeability is in the cylinder heads and intakes.

If I was going to put a stock motor in one, it would be a factory stock 6.4 with just a cam and lockout kit plus a 6.1 intake manifold.

If you're talking about an early 5.7/6.1 392 stroker, that's a different animal. You buy parts based on the block/timing cover.

I started with the 6.1 due to circumstance and luck, I had to build the whole thing up by each nut and bolt. I don't advise that for anyone, it's really not cost effective. I would have been farther ahead just buying a broken 5.7 early motor from a car and pulling all the odds and ends off of that.
