For your general 350 and no idea what year, I'm going with AC Plugs and some OEM wires.

You still need to Know whether they're Vortec Heads or Not....
I suspect Not....

Call Raul,+ ask him......

It doesn't matter one bit what kind of boat you have, or where you bought your motor.
What matters is what year, type heads, type ignition system, and other MOTOR information.

AC Delco MR43T if you have older Heads I assume this will apply to me 86' 350 w/ points? the auto parts store said bosh were better should i take them back .

Also is shell rotella oil for desiels better than castrol for cars ?
