best intake for this set up? Ive got a ls1 that has been done .50 over and resleeved with port and polished 243's, 4340 forged bottom end and rotating assembly/ flat top pistons, 3600 converter in a 4l80e as the motor is in a 2006 Silverado and came out of my catfish car. has 1 7/8 long tubes with 3 inch exhaust, custom CAI, and custom grind cam. if specs would help I can list specs but heads do have BTR .660 springs, ls7 rockers chromoly pushrods ls7 lifters and I know I'm missing a few other small things but I am looking to put the bottle back on the motor so intake mani would have to be good for a bottle. any advice would help!!! Thanks in advance!!

How much cam you running? Saying it's custom means ZIP. And it is impossible to go .50 over on ANY engine. .01 is the max overbore an LS1 will take with the thin wall it has.
You might be in the market for a FAST 102, but that depends on what you have.

Refer to above post. It's a heavy truck and 3600 stall even with 4.10's + gears more stall would be needed to run a bigger carb intake aka: CID,Super Vic/Jr etc..... $$$ for the MSD or FAST intake or do a Dual plane carb style intake.

AH!! Resleeved! That makes all the difference in the world! LOL! I'm gonna guess it's 50 thousandths over stock. You might want to have your machinist explain things to you when things like this are done. No harm though, at least now we are on the same page! lol

what size of a hit would be good on that motor I'm between 150 and 200 once I get the motor broke in.
