well, got my engine on the dyno today. After a full rebuild, new pistons, heads redone, new blowers, etc. Mike tkach on the board here built the shortblocks for me, and i did the top ends. Here's the specs

468 ci mark iv blocks
manley h-beam rods
je flattop pistons
speed pro plasma moly file fit rings
custom crower hyd roller blower cam
morel lifters
isky sp endurance springs
crane gold rockers
arp head studs
cometic head gaskets
dart 308 aluminum race series heads w/light port work
dart adjustable guideplates
b&m 420 mega blowers underdriven
holley 850 marine carbs
no intercoolers

engines made
804hp@6200 at 6.9psi of boost.
798hp@6000 at 6.6psi of boost

over 700ftlbs from 4000 thru 5800 rpm. These were budget builds, that turned out pretty nice for what they are. Little old school engines.

I must say thanks, to all the guys that have given me advice over the past few months. Its invaluable.

and a few others. Kudos to guys like these who are very knowledgeable, and yet take the time to share their knowledge with a young buck like me, and im not even spending money with them. I told the dyno operator today when he asked me before we even started the engine "if they make 700hp at 5psi i am a happy guy". First warmup pull we did 747hp@5500. I was smiling.
