Hey, I'm planning on building a 383 stroker, I called Lloyd Elliot at Elliot port works and he recommended Lunati 60123 cam with TrickFlow 23 Degree heads. Does anyone have those on their LT1 build and any dyno sheets? Also, what is the best quality as far as pistons, connecting rods, push rods, etc...All inputs are highly appreciated!

Lloyd recommended you going with an off the shelf cam and heads or his ported trick flows? Honestly best bet would've been to ask him these questions when he was on the phone. He's probably built more combos than most people on this board put together.

He said any forged internals since I'll be using forced induction but I don't know what is the best brand such as mahle, JE, Diamond, and so on.

BALLSS

Mahle pistons and Callies (forged) crank & rods are considered very good. Heads & cam combos are best sourced from LE or AI.

"who" builds the motor regardless of the parts used is a critical element. The best parts in the wrong hands mean nothing. Machine and assembly work need to be spot on and a concise build plan with clear end goals needs to be established. High end parts and qualified/quality work are not cheap so don't expect bargain prices.

once your new bad *** engine is done a tune and all "supporting" mods behind it are also needed to allow the new found HP to get to the wheels.

I have that cam with AI heads in my 383....made 428/370 with my stalled 4l60....very happy makes peak HP at 6300rpm and pulls very hard all the way up!

So you guys think I should go with AI heads instead of the trickflows or get some AFR heads?

From the flavor of your thread here, it looks to me that you'd be wasting money with AFR or Trickflow castings.
AI or LE can port your stock LT1 castings, or a set of cores, to get you near 500 rwhp. Are you shooting for more than that?

WHTLTN2

If I can shoot for more I'd shoot for around 600-650 if that's even possible then I'd put a 400 shot on it or slap a turbo on it.

Okay now you're being unrealistic....

Yep, this guy's either incredibly naive, or just trolling.

Prob why Lloyd recommended shelf parts

I'm building my friend an 87 monte ss 383 stroker lt1 and I'm taking out the lt1 that's in my camaro and putting it in the ss and i'm building an LQ4 408 with twin turbos and he told me he's looking for that i'm just a middle man.

Getting 600-650hp from a NA LT1 is quite the feat, adding boost after that isn't going to happen without a complete rebuild. NOS maybe, but not a 400 shot. IMO.

Realistically getting 450rwhp from a built NA LT1 383 through an Auto is possible. And can be daily drivable too, if done right. But 600 isn't.

Shoot for a 450rwhp 383 and add a 200 shot of NOS (build for NOS while you're doing this) and you have a realistic goal.

I might go 385 or 388 if it feasable i might go 396 or 398 but then again it might not be streetable and be crazy loud so that's what i'm thinking about.
