A 360 is a 4.05 bore using a 352 crank and rods. 3.50 stroke
A 352 is a 4.00 bore using a 352 crank and rods. 3.50 stroke
A 390 is a 4.05 bore using a 390 crank and rods. 3.78 Stroke
352 rods are 6.538 to 6.542
390 rods are 6.486 to 6.490
Just what combo are you looking for?

Garbz,
I was just looking to use my case bored .030 over and a 390 rotating assembly for a 383cid motor. I had heard about use of 352 rods with a 390 crank and figured if I could find pistons with a compatible compression height I would use those, or some i could machine the rod length difference off the top. I know the 390 rods
with that crank would be the easy route and hope to find those parts for this build.
