Any fast 318s out there?

Yeah but the 318 heads are too wimpy to make great power. I luck out and found some MP 360 heads with the 2.02 intake valves, it was based on the great 308 heads but these were never drilled for those air ports in the exhaust ports.

Still some old 1971, 1972 J heads--or those $$$ X heads would wake that motor up. I don't care what the book says, 360 heads on my motor made more power everywhere from off idle to 6500 rpms....try to get 6500 rpms with those 318 heads.

Really if my motor had a forged crank and better rods, I would twist it to 7500 rpms with a solid camshaft.

The motor will like gears, my ride has 3.91 gears with a 26 inch tall tire but if do over, I go with 4.10 gears. Yes the little motor screams on the freeway at 75-80 mph but runs just great to triple digits. Back in the 60's cars came with 3.55 gears and higher--4.10 gears and people drove on the freeways everyday (yes they brought new cars every 3 years too, lol.)

Only down side is low MPG but an overdrive trans would be of big help...too bad its not that easy or cheap to do. So I would build for RPMs with the best parts.

A 360 motor would be cheaper to build for the same cost.
