Vortec-ify?

[dkellogg3]

1994 4.3lx with Edelbrock 4bbl.
S/N 0F281912....

I may have a line on Vortec heads and intake. Could I do this? Would this be bolt-on? Would I need anything else?

If this is possible what kind of power increase could i expect? Any potential problems?

Thanks in advance!

With the right pistons how much increase? Probably not worth the effort. Would I have to reprop, too?

Re: Vortec-ify?

if your going thru the effort of changing pistons, then I would do a complete re-build. I went the route of vortec heads on my 5.7 liter along with intake and a cam change.

just changing the heads will net you an increase in power like Bond-O stated, however it will also increase your compression ratio. this will put you in the area of higher octane fuel.

what is the problem your trying to fix. if it is a speed of boat thing, that is fully understandable. remember, speed costs.

no particular problem... just thought if I could pick the parts up cheap it might be worthwile. With a 3-1/2 year old and another on the way, probably not worth the time it would take...

Thanks for the input guys.

with a growing family, you may be upgrading the boat to a larger one in a few years. I say, enjoy the boat you have, then get the one you want in a few years.
