I'm Awesome
Sharpe IMO FWIW just run the ramjet 395 cam ...you will make almost just as much power with less compression with iron heads vs the zz4 aluminum head setup at 10:1 . You will have a ton of vacuum , no ac bogging issues , and lets face it 400 ft lbs is no slouch since you mentioned occasional towing . 364 hp 412 torque per Hot rods dyno test.
