Multiport coverted to carb!

A 750 would have no velocity. A 440 is probably a bit much for a gen 2 but for a 3500, it is what I would start with. I wouldn't even consider it by modding an upper though, only a lower.

Why a little 2bbl q-jet? Put a 4bbl 750 q-jet on it and see if it holds together.

A 750 would turn that motor into a giant fuel pump LOL

Trust me the two barrel is plenty and can raunch these motors, specially with no rev limiter

Sappy: how would you go about modifying the lower? Getting something machined? I have often thought about putting old iron heads/ intake on a mpfi engine anyone tried that?

And if anyone considers doing this i would suggest gettin the plenum and lower intake runners steamed out.

I think that was made for a gen 2 swap in a Chevette, just a random pic i have on my server.

It really wouldn't be hard to make one if you have access to a TIG.

TBI iron heads work well on block that came with mpfi??? Are the valves staggered all wierd like injected engines?

Push rods from old motor?

[Superdave]

you'd have to change the pistons out too, the iron heads have huge chambers. Also prepare for a drop in power.
