If I ever get to go down the road of motor work for fun, the money spent on heads, cam (with or without bottom end), transmission, rear end, etc... would roughly equal the amount spent on a Gen 3 or 4 engine swap. Mmmmmm... L92/L76 and 6L80E... <DROOOOOOOL>
Sad part is, right after I finished my 383 install, a buddy of mine wrecked his twin turbo 2006 GTO, and I bought it. I briefly thought about putting the LS2/6-speed in my 94Z, but it was 'done'. So I'm putting it in my '79 Z28. Don't know if the APS Twin kit will make it in the '79, but I'm definitely doing the LS2, 6-speed, and the GTO interior...
