Re: 1978 Mercruiser 898 Repower
And thats fine... With that basically stock Merc 260 cam, an edelbrock performer intake, 650 carb. Flat top pistons, I should be about to pull close to 300hp. I got my 305 out today, the block was cracked, BAD.. I knew it was cracked, but it was worse than I saw while it was in the boat... Also I broke out the side of the block to see how it looked, and the water jackets were filled at least half way up with rust, and sandy looking sh*t. Im supprised the thing even worked at all. I used it 5 times last year like this! the heads that were on it, have small valves 1.76 and 1.5 i think. with 60cc chambers. With the flat top pistons, my compression would be close to 10:1, I suppose I should use the heads off the 350? would there be any benifit to using the 305s heads?
