Hi All,
Trying to figure out what the correct carb was for mine and make a decision...1984 GMC High Sierra 2500, 350 V8. Bought it a couple weeks ago, the previous owners brother in law replaced the original Quadrajet with one that looks like it had been sitting in a molasses vat for the past 10 years. Tried to clean it, I believe the internals are just roached and it has so much seepage doesn't appears worth saving without a major rebuild I don't have the time or patience for. Choke linkage is all screwed up, and they decided to drill into the throttle linkage and connect the TV cable for the 700R4 just by destroying the cable and sticking it in there.
I believe that mine would have come with a Hot Air Choke and be a M4MC model quadrajet...should be 750 cfm....does that sound correct? I can't really find anything in that cfm range on the shelf around here, and don't want to get a 600 cfm Eddy or Holly as I plan on building the engine at some point in the next year or so for more hp/torque and don't want to be short on air and fuel down the road and have a $300 carb I will have no use for (not sure if making it a built 355 or so or going 383 stroker).
I found some good looking reman/rebuild ones on ebay for around $220-250, and the M4MC type I believe I need....thoughts?
Thanks!
