Any suggestions before I attempt this tomorrow? anything I should know? This is for a buick 350 The engine is 73 2bbl, the manifold and carb are 70. Ive done this on small block chevys before, this is my first buick. 2bbl to 4bbl, will all the linkages be ok? bolts? they all look the same, not sure of the linkage though. Ive got some studs I thought i would use as a guide, used to work good on the sb chevy.. the manifold weighs exactly 56lbs by the way not that thats relevant but I thought I would throw that in there in case it ever comes up in a trivia contest sometime. help is appreciated. thanks.
I would guess the likage bracket and cable is different. Do not attempt this until you find out as now you have car thta will not function. Bolts should be the same.
I remember something about later heads not accepting earlier intakes or vice versa,something about water passage changes but maybe someone else can chime in.
Actually, it's the heads matching with the block that have different cooling passages. '68- early '72 are different from late '72 - '81. The intake to heads to should easily interchange. TA sells one intake that covers all 350s.
thanks for the heads up. I was wondering about that too, thats the exactly the kind of thing I wanted to know. some kind of show stopper like that. I got the manifold all prepped, tomorrow ill rebuild the q jet, then I need to find an air cleaner for it. I would love an open element one that I can use my stock air cleaner top with. any ideas.
ya turns out the later heads have AIR holes that match up with the intake. When i put the older manifold on, the 5/16" AIR holes were exposed and leaking exhaust and making a horrendous racket. So I had to take the manifold back off and tap the holes and put set screws in there. Bad luck, a snapped off a tap in one of the holes and it is still there cant get it out, so i JB welded over it and hope it holds tomorrow when I fire this mother up. Geez. IF not I dont know what Ill do. Ive tried like hell to get it out to no avail. So beware if you are swapping an older manifold onto later heads.
