so I am confused, is it a 413 block or a 426 block? What would the compression be with the pistons you have ?
Thanks

In 1971-74 mopar casted a 413/426 HD block for med truck. I started this engine with a 413 the bore is 4.187 std and bore to 4.250 std 426. This is a + .063 413 bore. The std 413 cyl wall on this 413 block is .280 FYI I check a +.030 426 hemi .180. Back in the 70s we used a 413 car block and Max wedge piston High school kids with no cash just old dodge part. I will add the casting number of the block today.

What will compression be with the pistons that are included. I know it will be an estimate.
