I have a 96 GSR head that Im going to put on my 98 LS(b18b1) block. Everything is mostly assembled, and the engine is set up for a turbo (no more than 14 puonds of boost). I ported the head slightly, just cleaned everyhting up. I get about 5 or 6 more cfm than stock. I dont have an intake man. or a throttle body yet, and I was wondering if stock parts will do. Or if afterarket parts like JG edelbrock are worth the extra money?
Has anyone built this kind of motor and seen results?
