Omc 4.3? What did i buy?

[Scott Danforth]

a running Vortec long-block in a truck from a salvage yard is $250

I suggest you buy that and simply swap head gaskets and core plugs.

From the 2 motors i have 3 Possibly good cylinder heads. Im taking all 3 to the machine shop. Hoping i have 2 good ones to work with. Im trying to make this work with what i have. I was under the impression that all marine engines must be a roller cam to work properly and that is why i started this thred. I would love to have more power but i think im stuck with what i have for now. But if i do get ahold of the right long block where can I find a 4 bbl intake for a vortex head that wont break the bank?

As mentioned eBay or here for the intake https://www.michiganmotorz.com/products/marine-parts-accessories/intake-manifolds/v6-4-3l

you didnt read the link I posted in post #11, did you?

no way to convert the flat tappet motor you have to the roller you want short of this only 3-step method:
step 1 - sell what you have for a small pile of cash
step 2 - empty contents of wallet, bank account, etc onto small pile of cash, making it a bigger pile
step 3 - take bigger pile of cash and buy what you want.

You are correct! I did not read your post untill just after. Good read, very informative. As for the pile of cash...... i dont have one of those.
