Could you post as much info as possible about the swap? parts required,part #s ect.Thanks

OrangeChevyII

Ehhh, I bought a can from GM for 109 bucks,Picked up some ZR1 springs at the local speed shop for 80, a timing cover for a Ls3 vette for 56 and a three bolt timing gear for 30. I don't know about the part numbers, I'll look tomorrow when I get to work.

It's a fairly easy job.

Appreciate the info,Here's a question folks will want to know.How does it feel? lose any down low? does it just hit harder when coming on,how would you describe it?

OrangeChevyII

The dyno sheet answers those, it didn't lose any power what so ever down low. It's alot broader. The curve is continuous all the way to 6500 insted of falling off at 5500 or so. Feels just like a stock truck till you floor it.
