It's either a 352 or 390 block.
By Dave Shoe - 01/13/2002 6:28:06 PM; IP 216.243.191.45
428 blocks weren't yet available, and 406s were not made in 1964/65. FTs were available, but they'd have an oversized distributor pilot hole, or a pilot bushing for the distributor.

The chance that it's a 427 is about nil.

The only way to get a good idea is to pop a core plug or two in the block and measure the gap between cylinder jackets using a drill bit

Dunno what a 352 gap would measure, but a 390 cylinder gap might be close to 16/64" (at the largest gap), a 361/391 FT close to 12/64" (at the largest gap), and a 427 close to 8/64" (at the largest gap). Obviously, I only deal in increments of 1/64" when talking water jacket gap.

As far as stroke goes, that's tough to accurately measure with the head installed. If you do decide to check, start with the piston at top dead center and make sure it stays in the same postion in the spark plug hole from top to bottom, and that it doesn't slip across the piston. You can also look for a counterweight on the flexplate if the #1 piston is near BDC.
