few lt1 mod questions I am new to this site and have a lt1 in my camaro I have heard that there are limitations 2 stock lt1 -lt4 intakes i have a lt4 with fully ported afr 220s with high compresion with stock opti spark I have no idea yet just how much hp/torque the motor is making but am always looking for more power what is the best intake for these motors any info would be great or refrences to any particular cars also am looking to do the ls1 coil pack upgrade any info on this set up would also be appreciated.
As far as intake manifolds there is nothing off the shelf better, some guys even went custom built and din't gain much. The LT1/LT4 intakes are not perfect for all applications but are pretty good.
About the intake, just have it ported, and gasket matched, really cant get another off the shelf intake..... Only way to know how much ponies you got ..... take er to the DYNO, let us know what she pulls 
Sounds like you got a good set of heads already what kind of cam you got in their??

yeah which type of cam you got?? And guys, if there is a big cam is it necessary to change the valvetrain of the heads?? ie: AFR heads..Some people say me to change AFR's springs and retainers with comp cams' springs and titanium retainers.. Is it necessary??

I port mine just enough to match the gaskets. they are very good from the factory. The only way to really improve them is to have them extrudehoned. but man, $$$$$$$$$$$$$ for that process.

Sounds like you got a good set of heads already what kind of cam you got in their??No offense I wont give a way my cam specs only thing I will say is that it is a big solid roller verry big nos cam the car has been 2 the track several times now and I am having a problem with it braking up for a split second I can watch it on the wide band and I think it has to be the opti spark looking to upgrade any sugestions.I still have the afr valve train but just pulled the motor 2 check over was going to go threw the heads why are they upgrading away from afr stuff .I had aset of 220s also on my sbc 383 and my engine guy said the springs were junk he didnt like them we upgraded to k motion but ended up selling evreythign for new project.I dont want to give away to much about my setup for personal reasons but the car runns verry well for being a nos motor on hp.
