This was originally a TBI oriented manifold, but was converted to run a blow-thru carb setup. I never got around to building the blow-thru setup, as I eventually went fuel injection. Runners were ported a little bit, so I would recommend them being finished properly by the buyer...

25.00 for what you see in the pic (not shipped)...

Will a normal GM TBI bolt to it?

Joe, a 4-bbl TBI yes, but to bring it back to the original 2-bbl TBI system like before it was modified then it would need an adapter plate...

Edit: Also wanted to point out that it is for a non-centerbolt style head, its hard to see that in the pic, so it is for the 86-down SBC cylinder head. It could in fact be used for the 87-up style, but would require the center four bolts being angled properly...

Sorry for the late reply. I think I'm going to use vortec heads on the boat, so I guess this won't work for me.

Thanks though.

Bump, I will include a Mr. Gasket carb spacer (squarebore to spreadbore) with it for an additional $5.00, so for $30.00 you get both. The spacer alone is worth fifteen bucks...
