I've got 2 660's on my 614 hp 428 with a tunnel wedge...it's awesome and no problems leaving the stop lights in a mild mannered disguise for those road dogs that want to cite you. Although how much of a disguise can you really hide behind. Also I get about 12mpg on the highway with my TKO in 5th gear when I don't get too foot heavy with the throtle. Response is excellent even at lower RPMs.

I'm assuming your 660's are the mechanical secondaries with the center squirters. That is what I have on my 460 and love them. The only thing I'm going to do over the Winter is to mill off the air horns. Should help out the air flow to the primaries.

I did not think you could put a 460 in our cars, maybe just my car...lol. Hmmm, I wonder. I saw a nice 521 based on a 460 block, but I did not think it would fit!

You can pull the motor, but not the heads if you have non-removable studs. You might be able to if you jack the motor up a couple inches, but I'm not sure.
