Default what am i lookin at

What kinda rwhp am I looking at, I am just finishing up a project that I got off of someone who ran outta money during his build Here it is
94 Z28
383 stroker fully forged
Cc 306 cam
Milled iron heads with intake and exhaust ported
Ported intake
Spec clutch
M6 3:42 gear
Lt's with OR/Y and cutout


Sorry I'm not real familiar with lt motors, first lt motor build and I'm not leaving anything out stock objectors and all, which leads me to some questions can someone give me an insight as to what an estimated hp and ET would be, and I do have the driver mod, not yryin to get in a ifs and buts kinda thread but the car isn't on the road yet so I'm just wanting to get sone insight if its not performing like it should when finished.. Thanks

I'd be afraid to run stock injectors on that motor.

30 or 32 and get ported aluminum heads and you will get more horsepower

I've got a set of stock heads that aren't ported but I decided to go with the cast because I just prefer them better with nitrous they're heavier and have less chance of lifting a head gasket

wrong dude........all he will do is loose some weight..........and it would allow him to run more compression with pump gas.......as for iron lt1 head to aluminum the flow numbers are almost identical.......as for injectors id toss 36's in it.....

built correctly it will never happen.......with good gaskets and proper machining and a good fastener it will not lift a head.......i know people spraying in excess of 300hp and not lifting aluminum heads....

yeah I understand that it can be made not to lift but I just like em better since I was using stock head bolts..

I'll prolly go with 36's like you said, thanks

Any one have any idea on rwhp, or some et's? Lol
