Ok, have a set of vortec heads so max lift is about 480,470 to be safe.I have installed Beehive springs (comp cams) and roller rockers,1.5 intake and exhaust. Blew my radiator so its sitting outside the car now. Thinking this might be a great time to up grade the cam from stock. Sooo, cam specs out 1,000 to 5,500 rpm, 213*intake/219*ex., 454'/468 lift with 112 lobe sep. Will my vacume brakes continue to work and will the 1986 computer chip handle this ok.
