Hello, I bought a 1989 boat with a 302 in it. I noticed that it could have had a 302HO with a differant firing order. What makes it an HO? Just the cam? Why not keep the same firing order, but up the cam specs.

Cam, pistons, heads, intake, carb or FI, timing chain and gears comprise an HO. FoMoCo went to the 351 firing order to keep cylinders 7 and 8 from firing side by side. It was always a source of missfire.

By the way, welcome to M&M !
