replacing motor need help

[bigbenrusky]

well i know this is kind of a sour subject in these parts, since there are so many threads on this subject but i think i might have a little twist to the question.. i am replacing a gm 305 motor for a 350 small block. i am in the process of ordering parts for replacement as well. now my question. what do i need to replace on this engine? i am getting a new exhaust manifold due to the old one being cracked but i am looking for high preformance parts to replace to get the best and longest use of this engine. i am looking for spark plugs and wires, any subjestions? also i don't know what else to order. can any one help? the boat is a 1985 century 3000br. thanks in advance.

it is a 1985 Century 3000br it is for pulling and just general play, and the ocassional play. i will post a pic so that you can see what i see as far as the boat is concerned.

i am looking for spark plugs

Ayuh,..... AC Delco, MR43T is the Sparkplug #s you want....

I'd just swap over All the necessary parts from your old motor,+ Then worry about whatever you're lacking......
