I think it's a 318... you get it to idle under 1K with that size cam, I'd be surprised unless you lock out the distributor.

You're correct. It's a custom built 318. Basically it is a 340, but with a 318 block. It generates about 425 HP as well, not bad for a daily driver, $20k plus, has been put into her so far.
