I have a 2002 ls1 long block with ls3/lsa style heads on it. I had this setup in my 2002 camaro ss with the lsa blower on it. Motor made 530 to the wheels on a conservative tune. Could have made a lot more power if I had a bigger fuel system. Anyway heads are ls3/lsa style heads rework to fit on a 5.7 small bore. Cam is a custom grind. 21x/23x 6xx/6xx lift on a 117 lsa. Motor gas a head stud kit, slp Timing Chain, slip oil pump, btr .660 springs and a factory gm Ls1 oil pan. Bottom end is atockvwith 8990 miles on it. I have a video of when the engine first fired up with the lsa blower on it. I'm going bigger so I no longer need this setup. With the lsa blower, e85 and a better fuel system u can easily make over 650 to the wheels. Rocker arms, rocker stands, and pushrods aren't included

free bump, what did you have to do to make the heads work on the LS1 I thought LS3 heads would not work on an LS1

wait until the ls3 goes into the car. My motors on order, recieved my prc 260cc heads last week. The firewall is getting smoothed and painted now. Hope to have it all back together by spring of next year.
