1994 4.3 vortex exhaust shutters & intake manifold

[philbullet]

Ok I ran into some problems.
1st. Was I had a stuck valve and water in oil, after leak down test and investigation found a pin hole under intake mantifold so i need a new one.aluminum or iron and best prices?
2nd may have gotten water from exhaust , backing up in rough water trawling with no shutters so i need to add these but I know there's different type so how to tell which ones I need. A2, A3 ?

With just a pin hole you could probably just JB Weld, but Iron will last longer and Aluminum would be cheaper. If your not in salt water should be fine.

Not using a serial number, you should have part number 807166A3 item 6

It's a repower, donor boat, truck moto, do ss num. Would match.
But it is a vortex heads and counter balance shaft..
Thanks.
I think iam going back with iron because i do use it in salt water.

Oh, 4 barrel carb.

Vortex? Sure you don't mean Vortec?

BTW...Vortec heads will only be on motors from vehicles 1996 or newer.

Yes it's Vortec heads, plugged off the non used holes for intake but I ordered a new 8 hole intake and the
A3 shutters.

Huh,..??..??

The angle, 'n depth of the intakes are different, as well as the number of mountin' bolt holes,....

That picture doesn't appear to be a Vortec intake, to Me,...

I agree...It is not a Vortec intake. Has 12 mounting holes.

Heads are vortec, sorry holes where drilled and tapped into heads for this intake.There the open chamber in exhaust ports not the old school heads or pre vortec.
With that being said the intake is not a vortec intake with 8 holess but with 12 holes.
But that intake is garbage because of rusted out hole.
Not taking that chance again.
That intake was the only thing used on this long block that came from a Donner boat/motor.
I should have just changed it from the start.

Seriously? Why would anyone do that? Surprised it even worked.

Ayuh,.... Considerin' the intake ports are .200" higher on the Vortec heads,. I'm surprised it didn't suck air, 'n run lean,.....

Nope no problems there, the only problem was I used a the used iron intake from the donnor(400.00 boat) and accumulated a small pin whole under intake and was getting water in oil.
The only problem with using that intake on vortec heads is a couple bolts hole won't have alot of threads to catch, but my brother (mechanic) had a solution for that.
But i have a new intake on the way with shutters.
Also changing out to self guiding roller rockers and new push rods.
