I'm just wondering if any of you guys might have an answer on this. I have a 330 MD block ( FT series of motor ) that I am wanting to use if possible for a rebuild for my '63 F-100 4x4. Does anybody have an idea what kind of overbore they will take? Casting # C7ME, with an " X " cast into one cylinder bank in lifter galley. Current bore is 3.875 + .060, can this go to standard 4.050 390 spec's? Any help will be appreciated. Truck currently has 390 w/ T-98 combo. Thanks, Al

is it a 332 FE? if so, those motors will take a ton of over boring. a guy i know bored a 352 .080 over with no clearance problems. hope we're talking about the same motor.

Nope, its an FT series, a 330 MD, 3.875 bore x 3.5 stroke, has the long skinny 352/360 rods. Also came with a 9qt oil pan, which I won't be able to use, but might make a nice little grill for when your down by the creek. Nobody knows anything about this block, or what its capable of? Oh well, thanks. Al

yOU GOT ME...............:confused:

FT is the industrial version of the FE, also in this family are the 361 and 391. Block is heaver cast than a standard FE unit, crank is forged, all kinds of good stuff.
As to overboring it, I have no sweet clue.

You might try and locate a good engine rebuilder that has a sonic cylinder wall thickness checker. These devices are used by many high performance rebuilders to check for core shift and cylinder wall defects prior to putting a lot of work in a block. Then only to find that a core shift has rendered one cylinder wall only 0.060" thick after reboring.

OK, thanks guys. Al
