My Dart went 7.42 in the 1/8 at #3240 with my stock stroke 340 and 4.30 gears shifting at 6400. It only picked .006 over the 3.91 set I had in it before.

My Edelbrocks were ported by Curtis Boggs, it had a Hughes 3742 flat hydraulic cam, 11.2-1 compression and a Weaind X-Celerator single plane intake with a Quick Fuel Q-750 on it. According to the online calculators it made in the 450 hp range . I drove it a lot and once I installed a mechanical fan and shroud it never had any overheating issues, plus it ran on pump 93.

Personally I like all the benifits that go along with the aluminum heads .

I now have a 408 and it's a bear but also a lot more $$$ than I had in the 340.
