Okay, I agreed to race three ricers at the track tomorrow. They were bad mouthing Vettes. The problem is my car is still no running right after the mods were put on.This is what I have done. LT4 hotcam, LT4 heads, stage II port and polish, underdrive pulley, yank 2800, 3.73 gears, 58 mm throttle body, Ed Wright programming. LT4 intake, Hooker Shorties, 8mm wires. The car is sluggish under 2000 rpms and it does not down shift when floored, it just accelerates.
