MarkZ’s 505........ a little less cam, a little less compression, a few less cubes......on the BES dyno:
Basic specs:
new aftermarket "The Block"
505 CI
Molnar crank & rods - 4.25 inch stroke
OOTB TrickFlow 270 heads
Mopar Performance 337 intake
4150 carb - flows 1000 cfm
solid roller cam around 650 lift - smaller duration (Dwayne Porter spec'd)
10.9:1 compression
93 pump gas
Hooker 5209 2 inch headers
Made 713 hp @ 6000 rpm and 707 ft/lbs torque at 4600 rpm. I did not expect that much torque - it makes the same torque as my race car motor!
