All I really know about the motor is that it's a speed density EFI motor. And the upper intake sits opposite that of a Mustang.

It still runs good and uses no oil.

In another life, a cobbled together early model 289 short blocks (flat top pistons with large domed heads) with later model 302 heads (small combustion chamber heads used with dished pistons) and was able to get 10:1 compression

If I wanted to squeeze some more torque out this stock 302, CMC rules be damned, specifically, what would I need to source? 275-300 ft lbs is the target.
