If you look closely is a reverse "105" used mostly on the 361/391 FT series. The heads are 68 390 heads Mercury 4V or high compression 2V with 67.1-70.1 chamber volume. I think the "105" blocks were cast at MCC (michigan casting center) vs the DIF (dearborn iron foundry). As wisely instructed check the bore and stroke of the engine. The 361/391 both have a bore of 4.05 std 390 and the crank strokes are 361 at a 3.50 stroke and the 391 a 3.79 both used a forged steel crank unlike the std FE nodular iron. G.

I thought that the mirror 105 number indicated that it was a heavy duty 361/391 truck block. Look to see if the sides of the block have vertical ribs running down them. I hoping you got lucky and have a 391 truck block. They can be bored to a 428's 4.13 bore and probably bigger.

Oh BTW from what I understand as the FE was being replaced by the 429/460 series MCC was using the same castings for all FE blocks except the 428 and 427 which stayed at DIF until they closed. The "105" blocks were cast and then machined for the application needed be it a FT series or a 360 or 390. Generic yes but cost effective. This might be where the confusion is between the different blocks. Hope this clears things up a bit. G.

Heh. They quit making the FE in '76, but the FT continued until '78, if not a little later. Service block casting may have continued after that. So it's entirely possible that's an FT block, or a service FE block. An FE service block would be my guess.

I just scrapped a 78 F600 that had a 330FE/FT (this motor had a cast 360 crank and std 360 rods in it) under the hood. I think the FE/FT stayed in the heavy trucks till the change in body style occured in 1980. That's when the 370 appeared, I believe.
