I recently aquired a 70 cuda. The guy who had it before me does not know what is in the engine. I have not checked yet, but i'm pretty sure the way the car drives it has close to 2:76 gears. The engine runs good, but does not have any ummfff. It starts crappying out at 4,000 RPM's and it's all done by 4500 RPM's. It's a dog for sure.
I know gears are one reason. but i do know it's not all gears. I have a 68 charger with a hughes 2328 cam with 3:23 gears and it runs high 12's in the quarter, so gears do help, but with all the torque with a 440 it should pull decent with 2:76 gears. i do like the tall gears for the street, so i'm going to leave them in. I was looking at this cam.

I think the cam above would give it some pep if it will go in without hitting the valves.
It's a 440 engine, 4 speed 2:76(pretty sure, they are tall), seems pretty stock, might even have an RV cam in it. It runs good, but craps out around 4000 rpms. Not sure what heads are on it. They are cast iron, but i'm not sure if they are 906's heads or what yet.
