Is any machine work needed to use a flat tappet cam?
Specs say this is a 96 to 2000 roller cam block, can a flat tappet cam be used in it? Specifically, I have a new Comp Cams CL-600-4 and a PRW Gear Drive ,Dual Idler timing set.# PDCA2015
Does this short block come with the camshaft bearings installed?
Does this SBC 350 have functional mechanical fuel pump? Is a core charge required if no core is available? Is there a warrentee?
