if you are going to use a 454 tbi, you could have stolen the adapter
plate too and used it on a spreadbore 4.3 intake. early 454's had q-jet
intakes w/a adapter plate to accept tbi units. -pete
Is a TB from a 454 worth it on a 4.3L?

I'm getting ready to stick my Edelbrock TBI intake manifold on my 4.3L
TBI ('91 issue) over the next month or so. Hopefully I'll get rid of a
few of the "might as well"s while I'm at it, like replacing the old
lifters. Would it be worth it to bore out the intake to fit a 454
throttle body before I bolt 'er in? I don't have any head work planned
but I do have a set of headers installed so he's not choked too much
(Jimmy is definitely a "he"). A cam isn't totally out of the question,
nor are 1.6 rockers (I'd hate to have to replace my valve springs
though). Any opinions?
