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?
