I have recently acquired a nice bunch of parts to build a 393- a Scat 9000 crank, balanced Eagle Esp's, Wiseco custom dishes (14cc I believe) cut for TW Track Heat, FR alum rocker covers, Motorsport "victor" intake, nice SFI PB balancer, Scat flexplate, nice Probe girdle, ARP cap bolts, clevite bearings, childs and alberts file fit rings, a used "Nelson Specialties" worked billet MSD dist. w/ 2 box leads, two sets of plug wires, Milodon pan and pickup, alum water pump, melling oil pump and some nice CV pulleys and of course the bored and honed and clearanced E9AE block. For 1200 bucks. Supposedly this block came out of a van early ninties vintage. I have a '70 block collecting dust but it is in stock form. Is the older block that much stonger? I'd like to make a little over 500 HP at as low an RPM as possible - but no bottle. Also I was thinking AFR CNC'd 185's - how do they compare to the Track Heats on a motor like this - I want the most I can get with out spinning it real hard. Cam recommendations? I'm not afraid of solid lifters. Thanks for the input.
