What year 360?

Low compression is super easy to overcome with aftermarket pistons. And the 70's 360's had decent walls. I just had a 73 360 machined and had the walls sonic tested and they were thick enough to bore it .080 over. Sounds like your relying on old information from the 70's.

I agree 71-74 360 blocks have thick enough cylinder walls that they can be bored up to .090 over. Aftermarket pistons with 10:1 comp. so you can still run pump gas, head porting, a good mid range cam, a good intake and carb and you can make very impressive power from a 360.

I also have the original 340 for my 72 RR. I will be running 69 X heads that will be ported, a .030 overbore with 10:1 comp, a MP Purple cam, performer RPM intake with a 670 Holley Street Avenger and headers an I am expecting to be in the 400-425 range.
