i've posted this on here before just recently but bare with me here i go again.

this is the motor i have in my 87 camaro:

350 4bolt main @ .040 over, decked .025, scat 9000 3.75 crank, KB 18cc D dished pistons, eagle SIR 5.7 rods, clevitte bearings, arp main, rod, and head bolts, pistons @ 0 deck, dart platinum stg 2 heads that have been cleaned up gasket matched and shaved to 60cc, solid cam with 282/290-240/250 @ .050 .560" adjusted lift from 1.6 roller rockers, victor intake angle and gasket matched with 1" spacer, 850cfm holley DP. compression is about 10.2:1

computer sim says 522hp/ 500tq

it's in a 3500lbs car, runs of high octane pump gas, newly built and i haven't really got the car completely tuned yet for the track but the last time at the track i was running 11.7-11.8 at around 116mph. i should have some faster times based on MPH, it should go 11.4-11.5 with some more tunning and practice.

not real sure if you are going to be able to get the 500hp mark out of the vortecs, i know it's been done, but you will need the perfect set up. with some port work the vortecs have been known to get around 240-250cfm @ .550" i think it would be a little more realistic to expect around 420-440 from the vortecs. but they do have excelent combustion chambers "fast burn" that are very affective.

what is the intended use for this vehicle, what is the vehicle, what kinda budget are you on, tire size and rear gear ratio would all be helpfull info
