Default 408w AFR285 heads, 12:1 compression

What kind of power can be expected from a carbed pushrod 408 with 285 heads and a 12:1 compression, also still in the air on cam specs and intake mani. Planning on this motor for a dedicated 1/4. Bracket car, 94-95 chasis.

There would be something bad wrong with it at that power level.....

Exactly, it should make a whole hell of a lot more power than that.

I was gonna guess more like 700+ crank. Hey guys uber is up for ride of the month. Stop in and give an old car a vote. Seams like the 4.6 guys always show up in force and try to take the 5.0 guys out.

Throw that overboard. M blocks have horrible working issues and weak main webbing
