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 block 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.

500 HP might be a stretch with those heads and your relatively low compression. Nothing wrong with the heads but you need more inches, more compression and a cam thats going to make peak power in the 6000-7000 range to meet your 500 HP goal.

Don't be afraid of nitrous. It can let you build a streetable engine that you can have fun with on demand.

At the wheels...

I just had my combo listed below engine dyno'd, and after some tweaking it eeked out 602hp at 6400rpm. 10.7:1. Almost everything out of the box, except I did a little work to the intake and made sure the exhaust ports to headers was nice and smooth. I think a super victor would have helped a bit, and maybe a custom cam, but I feel I'm at the limit of the block.

Thanks,

It was my first time to the dyno, a little nerve racking. I could probably pick up a bit more if I put the windage tray back in. I removed it after reading all the stories about solid rollers and street use.

Thanks Joe. Our combos are pretty close, your's should do at least as good. Heck, your combo was a kind of blueprint.

I hope to have it tested in a month or 2 at the wheels and through the exhaust.

Back to the original poster, I've heard the 70's blocks might be better than 80's or 90's, but never got a straight answer. For sure the C9 and maybe D0's are the best. My block is a D9. I think you'll be fine.
