they made 626hp and 635 ft/lbs

Yeah I saw that article after I built my motor, pretty similar parts (makes me very hopeful ).

if you go alum heads, there no reason not to go 11-1 or under, your gonna run 93 octane anyway, so the extra point in compression is worth 50 hp or plus theres nothing like a bbc with alittle compression.
vinnys motor goes like this
10.60 @ 130 in the 1/4
top 5 run thru the hills 3 autocross
3000k stall, crusises at 2200 nice
496,4.310 bore, 4.25 stroke
scat 4340 crank,6.385 rods (200 thou longer then stock) h beam
afr 315 cnc heads killer, angle cut to 108 cc
wiseco forged piston, 10cc dome to achieve 10-9-1 with .040 head gasket
isky redzone roller lifters,manley swedged end push rods
ultradyne solid roller cam, .710 lift, 262,266 [email protected] on a 110
lunati alum roller rockers
dart ported single plane intake
pro systems custom built carb, based on a hp1000, this is the key, i did not turn a screw on the carb, when i did i screwed it up,lol, well worth the 800 bucks, hell a stock hp is 650-700, this is custom built, with lifetime tuning from todd at pro systems
2 inch primary headers, 3 inch oval exhaust with oval x pipe, going to pro mod spin tech mufflers, and 3 inch round tailpipes
that is full exhaust on his car in the drag video.
motor is 660-700 hp at flywheel, produces 540-580 rwhp, we will have exact numbers soon.

Here is the proof....http://i268.photobucket.com:80/album...hocked1060.flv Definitely a stout setup. I went with a little less compression due to our 91 octane fuel that is oxegenated sometimes. Now the solid roller can always be changed but for now I don't want to mess with valve adjustments. I bet it's not near as bad as myold small block. Seems like I was adjusting them every other week.

vegas, when using all quality parts, we need to adjust vins every 3k or so, so about once a yr.

I could handle that. I wasn't sure about brakes at that time either. I am running the 7/8ths master so I can run any cam I like. Big solid roller would probably need a little more compression though.

10-11:1
310cc runners with pocket porting this will be excellate if you stay under 7,000rpm

325cc normally are for over 7,000 or above 500ci guys and the 4.500" bore blocks hence they come with 2.3" intakes vs 2.25" intake vlv that the 310cc heads do

~240* @.050 dual pattern cam
lift .600 range
also got retro hyd roller cams as well

high rise dual plane intake

put you well over 600ftlb
