Ok.....The only “out of the box” vs ported data I have is probably not what you are looking for, because I changed a lot of the engine at the same time….oh well, here it is.
360, 10.7:1 compression (pump gas), unported Edelbrocks (stock flow ~242cfm), MP 509 hydraulic cam, Air-gap intake, 750dp. The car ran 12.49 @ 108 like this (3250# Barracuda, 4.10 gears, 727).
Same block, stroked to 410, 10.8:1 compression (pump gas), stage 2 ported Edelbrocks from Ryan @ Shady Dell (flow 293cfm), small street roller (248/254 @0.05 and about 0.576 lift), Air-gap intake, 750dp, car ran a best of 10.8 @ 123 with the Airgap intake. The car went 10.54 @ 126 on e85 and a Victor intake.
Like I said, changed a few more things than the heads (stroke, bigger cam, ported heads), but the rest was the same.
