What is the biggest anybody has built or heard of for the 504 motor. I just bought a Super C and a complete 504 motor for $500.00. It was cheap enough I couldn't pass up the temptation. I would like to make a Div 3 tractor out of it or as close to it as possible. Thanks for the help.

Seen a 153 taken to 220 cubes with 151 GM pistons and early farmall A rods. Put it in a IH 240.

why do you need the early farmall A rod?
What bore size is that?
looking to build a C
is there more room to work in a 504 engine?
thanks

Early A rods are smaller journal, the laters may be too not for sure. I pulled the rods from a early A, but there smaller then the 153 cube engine. Offset grind it to the A rods. The 220 cube was welded also to get more stroke. Pull the sleeves out and bore the block for the 151 GM pistons. I can't remember what size they were, but I think .060 over. You will have to go with allen bolts and heli coil the rods. Still lots of grinding to clear. The block was very thick, but have it sonic checked before you bore to far.

If I remember right the 151 bore is 4in. and the A rods are all the same size on the big end but the real early ones can be a little smaller on the wrist pin. (I just found that out the hard way)

I think 4.060 bore and 4.30 stroke. It was 223 cubes.

The 153 block will also has a stronger crank. If you really want to build a hot setup go to a full inch of stroke with some cunningham rods. Makes for one tricked out bottom end with more stroke and less clearancing.

I pull a 52 farmall super C and it has a 3 5/8 bore and that was a tight fit. the 504 engine block has that much more room to work?

You can also use a 153 out of a combine.
