I've decided on a 306 rebuild for my 85 roller motor with 110K. I'm gonna re-use my stock rods/crank/block, and it will be topped off with AFR 165's, 650 Speed Demon, Edelbrock RPM Air-Gap, and some sort of cam(doin research). Brands i have had my eyes on are TRW, Probe, DSS, and SpeedPro. Any opinions on these brands or ones not listed would be appreciated. All machine work will be done locally.
