Thanks Barry.
I was just reading on another forum that some have used the SP 2291 for 390 and milled them for use with a 3.98 crank.
Here's my situation. I've got a mirror105 block that was a 360. It was rebuilt, bored .030 over and they used the 2291 forged pistons. Now the bores and pistons are good, i've got 390 rods, 3.98 crank. Is it worth it to make these parts work or should I go with the new pistons.
Budget build for a 2wd 68 F100..
