I have a low mileage 440 from an rv. I’m thinking of swapping on edelbrock heads. I think the compression ratio on this engine is around 8 to 1. The 452 heads have 88 cc chambers if I remember right. The eddy’s are 75 cc. Shouldn’t that put it close to 9 to1 ratio? That with a dual plane intake should be a decent daily combo. Or am I wrong? I didn’t do the math. Just wondering if anyone has tried it
