Was trying to figure out why it seemed my 85 Mercruiser 260 seemed a little slow. Pulled plug wires, and found I only had 7 cylinders pulling. Number 3 has 30 Lbs Compression. I will prolly run it the rest of the season... It's now about 5.0 Litre V7. <br /><br />It runs great though, gotta love a chevy V engine. I'll do new/rebuilt heads, and a slight cam this winter.<br /><br />Bob in CO
