340 with big hopes

I ran a '71 340 Cuda back in the 80's, with a completely stock 2.02/1.60 Headed 10.5:1 motor, stock replacement forged pistons, added a Holley Strip Dominator, 850DP, MP.590 solid cam, 1.3/4" chassis headers, was around 10.1:1 with Fel-pro Blues, maybe less dependent on the deck heights etc. which were not checked. Ran 36 total on our old 4 star leaded fuel.

According to real world track figures weight/mph, this motor made 379 flywheel, Fully ported heads would add approx 30>40hp perhaps more?, and a good straight deck/heads etc., a touch more so your getting there.
