299 BTW I have a '64 t-bird 390 and it has dished pistons with no valve relief.
Shady,
Just curious - when was your Bird built?
Our early 64 Gal (October 1963 build) came with a 1963 engine - c1ae-a heads, c3 intake, c3af-bv carb, dished pistons. All the later 64's we've torn down had flat tops with valve cuts.
werby, without crawling under to look at the block. the intake is a 3J24 but has a c4 part number. I just have the complete engine, no car. but saw the car it came out of and was a 64.
Shady,
Thanks for looking!
I know it's a aide-bar to this thread, but significant I think:
Yours is YET ANOTHER 1964 FoMoCo, with 1963-style pistons, and with an early (October 1963) build date.
Maybe the flat-top pistons were a running change or half-year or something, although IIRC even the early dealer literature says 10.0 CR for 1964 instead of 9.6 CR for 1963.
Thanks either way.
