361 engine specs

Look at it this way, 361 vs 383, the 340 vs 360 the engine. "361" is so simular as the "383" performance wise set up the same, you can hardly tell the difference.We used to run a 361 in a 59 plymouth fury that ran in the 14 flat to high 13's.Heavy street legal car.Look at today's pump gas engines and 9 to 1 is a prefered compression ratio. If it all checks out you may not even need new pistons. I like them and "Free" is a good thing. I just looked up the compression ratios 9.0to1 361 9.2to1 383 10.0 to1 383 4 bbl . 1966 service manual
