ProComp/Speedmaster aluminum heads

It’s not that they make all kinds of power...... they don’t.
It’s about not wasting what you’re making.
Which is where the typical street/strip combo falls short.

It’s part of the compromise of the street use.

For street/strip stuff, I figure most combos are going waste 50-100hp..... so you need to overbuild by(at least)that much to reach the goal.
And it’s usually worse with a stick.

For a 3400lb street/strip combo with a stick and 3.5 gears...... trying to run consistent 11.9’s or better, I’d say it’s going to need an honest 500hp(std corrected flywheel)....... and have the car not be totally out to lunch....... or be racing in dog **** air.
Something like 60’ times in the mid-1.80’s....... speed about 115mph.
