Engine specs:
-4.500x4.000 Gen V block & crank, 6.385 h-beams, arias 12.5:1 NOS-pistons (never sprayed)
-Merlin iron heads, about 320cc intake runner, ported, 2.19/1.88 valves
-272/278 @ 0.050 cam, .700 lift
-Dart single plane, 1050 dominator
-2 3/8 headers, collector mufflers
I'm considering AFR 335 or 345 (with CNC chambers option) heads. That should pick up around 75hp according to AFR and get the car to the eights. They would also would lose weight on the front end as the car is now a little noseheavy (56%).
sg1586, what kind of 60ft you get? Mine are 1.29-1.31 on a good track.
My short times are 1.20 to 1.22 and 1/8 mile are 5.64 to 5.67... This just my 2 cents on that manifold...Get a victor... Your short times and 1/8 will pick up..If you go aluminum I think it's almost 80lbs difference but not positive..One other think if you have room rase the compression up closer to 14 to 1 that alone will make alot more power for you without a head change...I run a stock PG case and 1.76 planatary also with a 4.30 gear and a 16x33 tire...On a real good day with good track it will go 8.60s @ 158........
