while you are thinkin about carburetion, 9or anything else) remember this acronym:KISS. it stand for Keep It Simple, Stupid....if you can do something several ways, choose the simplest way. That comes to carburtors..youll find one 4 bbl easier to deal with than 3 2bbls. But then, 2 2bbls looks a lot cooler than one 4 bbl, thats for sure. Youmay well have to.....how often & what kind of smog checks you gotta deal with where you live? To pass, not only are the emissions havin to be within spec, all the stupid crap they hang on the engines has to be there too. out here its every 2 years, so Ill have to yank the manifolds, hang the stock crap back on it, get it tested, then put all the good stuff back on. What you may want to do is pick up that head the fella offered, do all your mods etc, but get the car smogged before you actually do anything to make it run better. KEEP THE OLD HEAD & parts! keep all the stock crap- youll need to swap everything back for the test in the future. **** Democrats. Consider it practice. And like the guy said, rear gears that get you down the road drag style takes a toll on your mileage, while tall gears that let the engine RPM stay low at highway speeds slow your out of the hole acelleration....keep all us old farts posted, you picked up a couple dozen instant uncles....mutt, Ca.
