I had the same 505 combo in my S/G Camaro. I went with a 4.500 bore with the rest of my parts in the new block. It is a 540. The increase in bore size and the 4.250 stroke work great. I picked up 6 MPH on the stop. HP on the 505 was 835 and the 540 is 870. This is on a tight dyno with real numbers. I would buy pistons and a block and call it good. Some flow bench time dont hurt and I ran mine up to 14.8 from 13.2 for compression.

6 mph is a good gain. it had to have picked up more than 35 hp

Certainly you don’t need to be fast to win....but if you’re buying new parts....you should probably make it big as you can afford...you can always de tune it....
I may not be a good example...lol |

Along time ago, a friend told me that if there isn't a penalty for cubic inches, get as many as you can.
