I don't see what's so wrong with a 352? It was pretty fast in it's day and I'm sure with a good build and a few aftermarket parts you have power like the 390 without the fuel guzzling.

The tranny is probably a C6 3 speed. Had it been a '65 it would have been the old cast-iron Cruise-O 2 speed. The C6 is a great tranny, but in your case the one you have is only good for a FE as the bellhousings are inseperable.

Wait a minute... Why do you say it's a 352? The 360 and 390 also used a 352 stamped block. I question it because I see you have '67 Rods and appearantly are using 410ci pistons. I wouldn't go tooting that horn yet. Get the numbers off that crank or better yet on the flange that the flexplate (or flywheel) mounts to, there is either a square notch, a half moon, or a circle (or a combo) cut into the flange. This is also an indicator of what crank you have it the block. I know for sure, having just a square notch means it's a 390 crank. Having both a half-moon and a notch means 360. There could be more combos, but I can't remember more. I'll have to check into that method further.

Does anyone know how to surely decipher the markings that are cut into the rear flange of the crank?
