That's the original LS1 4 corner steam vent. Don't have a part # but if your looking for one you'll have to buy used, they don't make that one any more. What intake manifold are you going to be running ?

It's for a buddy of mine. We run jet boats. Mine's a Victor Jr. I got my crossover off of a 5.3 truck motor. Fit's the Victor with no problems. He's gonna run an LS1 intake and TT I believe.

My Cheyenne with a little 346 inch LS1 laying down some power vs a big block Daytona.

Very cool project.

If you cant find that old LS1 pipe anywhere you can do a few things to tie all 4 corners together. Here's what I did with my LS6 intake, https://ls1tech.com/forums/generatio...line-help.html

You could also go this route http://kurturbanperformance.net/home...r-vent-system/

How much does it weigh, sounds like it might be out of *that* turbo
