Actually, I measured the 4 cylinder 2.5L single TBI and it's about the same size as the 235 carb so it should be OK. Holley did make a single barrel TBI but discontnuied it it flows more than the 2.5L TBI and has a 2" bore.

I have seen them but I want to keep this kind of stealthy and stock looking. And those manifolds are expensive as well.

My thoughts about fuel injection usually center around putting a TPI on a big block. I've never gotten very far considering it for a Stovebolt.
I think it would be OK since I should be able to get a little more out of the TBI. And the stove bolts aren't as bad as the ford inliners with their intake setup.
