Here's the rundown:
360 block/half fill/line honed/decked, yadda yadda yadda.etc....
4" stroke 4340 Eagle crank with SCAT 6.123" rods Icon 745's with a final static comp ratio of 10.5
Heavily worked EQ Magnum heads with 2.08"/1.60" flow 303-304 @ .630" with a min CSA of 2.35" (wasn't easy)
Eddy SV with plenum work and port match .5 open spacer Holley 830 or 1000hp with annulars
Hydro-roller 108 LSA 250/252 @ .050" .660"/.590" design (not actual)
Schoenfeld 1 5/8" 1 3/4" step headers with a 3.5 to 3" hillbilly merge collector.
I have a great deal of faith that this combo will produce great power for what it is--What say you Moparts? J.Rob

Don't know yet but soon, very soon.
Gotta love ya Brett!
I like your guess (more like estimate) on HP but am searching for about 20 more ft/lbs.
At this point I am just really curious if I can get the FPS on the small ports down enough to get this many cubes to rpm enough. J.Rob

so a couple are thinking along the lines of 1.45 hp/ cube. i would expect a bit less, more like 1.2hp/ cube. small HR cam with a small port will make great torque.

I say small port makes poor TQ (peek) and just not good for much of anything air speed in port just kills HP AND TQ. I may have been tick aggressive on both my numbers on Robs dyno but I bet he gets close to the 600 HP.

I am not sure if I will reach the 600hp benchmark with these heads; however, I am confident it will come very very close.
Dan--What would you consider a large hydraulic roller? J.Rob
