Nice truck and engine! I love the LS1 in my truck, missed my goal of 400 rwhp by 16hp but the 5.7 makes a great engine for a RCSB.

No. I decided about 3 days after I bought the turbo piping I wasn't going to do a turbo lol. It was an impulse buy. After that I was set on wanting a PD blower on the truck... just needed more cubes first. Something about the whole 120rwhp bolt on just has me sold.

Those are still great numbers for NA! I know I will be significantly shy of that NA as I'm going with a smaller cam (not sure on your cam?) and don't have the full bolt ons yet.

I've always loved LS1 trucks... I know 6.0s can be had cheaper and later years are stronger... but something about the whole F-Body/Vette engine gives it that cool factor imo. Plus any time you can shed 100lbs on a fatass truck is always a good thing lol.

I had a LS1 with the thunder racing 224, in my old rcsb Sierra and that thing was at the bottom of 13s on a 90* day. Through a bone stock 60E and 3.42s nevertheless lol.

Just a few goodies that showed up. Decided I'm gonna stick with the 241 heads as I got a great deal on a bunch of gaskets, bolts, LS2 trays and LS7 lifters. Still waiting on the cam to show up.
