New 306. AFR 165s or 185s? Need Advice!
I have a 91 5.0, 5- speed coupe. 3.55s, = lenth headers, off road h-pipe, flowmaster cat backs.
The engine is being built. It is a 10.4-1 306. It has the .499-.510 trick flow cam, trick flow street intake. 70mm throttle body, c&l 76 mm mass air tube w/ 24lb metering , 24lb injectors, adj. fuel pressure reg, windage tray, 1.6 roller rockers, underdrives.
I drive this car on weekends and it will be about 70% street 30% 1/8 mile track. I want to put the best head on the car. I dont want it to be a total pig on the bottom. I don't mind trading a little bottom end for a huge gain in the middle to top though. I don't plan to ever twist it past 6000 rpms. It will have forged pistons, stock rods and crank w/ arp fasteners used through out.
I only want to buy heads once. I do use nitrous (NOS stage 1 & 2 dry, 75-150 hp).
I have run 8.47 (1/8 mile) on the motor w/ the stock long block. I'm looking for 8 flat on the motor.
Thanks for the help................
