I'm going to have it sonic tested hopefully this next weekend. That's a HUGE piece to the puzzle.



Is the 272 Block the same block as the 292 other than bore? Like, a 289 and a 302 are nearly identical other than cylinder skirt length. What differences are there between the two blocks other than bore?



And as far as the cams that are available between the 272 and the 292 (or even the 312) are there any differences?



It seems that it's a little bit of a toss up between guys that say use the 272, and others who say be safe and go with the 292. Kinda like, "do you like blondes or brunettes. I think the sonic test will determine that for me. Thanks for your responses thus far!

The two blocks are the same except bore.  All '55 and later Y block cams will interchange.

Hi Guys; I wonder if we could find the original factory weight of the 272 and 292 bare block. I know the weight is approximately 155 lbs. and a lot of interchangeable parts, but did they actually make a thinner cast cylinder wall for a 272 than a 292? Whatever, let's just keep the old Ys running.

Last year, I had to move a bare 272 block, and a bare 292 block several times. In that case, the 272 was heavier. I don't know by how much, though.

I think the cylinders were cast the same so the bore sizes would make a difference of around 10.5lbs. So assuming that all is the same but the bore, a 272 should be heavier.
