What is the maximum cubic inches you can get from a Bowtie 502 block and what pieces do you need to get there ?

Bore 4.560 if you sonic test and a 4.25 crank would be safe. 557CI

588

4.56 Bore
4 3/8" stroke

Personally, I wouldn't put a 4 3/8 crank in a 9.8 deck height block. The rod angle is to steep for my taste. I would stick with a 4.25" crank and you could go all the way to 4.600. That would make a 565 ci. You can take that block to 4.625" bore as long as you sonic test it. You should still have .250-.300 wall thickness at 4.625" bore. I have taken countless bowties to 4.600 with no problems.

I had a 502 bowtie at 4.600 with stock crank (think it worked out to 525 cu.) ran great with an easy 600 hp/600 ftlbs. at 9:1 compression with Dart intake and EMI exhaust. Loved that engine!!

That would make a 532 ci.

Could you guys explain Sonic Testing? Are you checking the thickness or strength of the cylinder walls? And you do this before boring, right? Otherwise you've ruined a block that could be used with less bore. Am I close?

Thanks for the input guys.

Yep, sonic testing will check for wall thickness.
