i just had a few questions about this switch into my 86 buick regal. i already have it in all i need to do is figure out my water pump situation for som reason it dont fit like the alternator bracket i off for some reason and its quite annoying jw will my 307 water pump fit on the 350 its givin me all kinds of roblems and im putting in gauges (oil pressure engine temp and volts) where do i hook them to the motor any help is greatly appreciated thx people

Long or short shaft water pump? With or without AC? Alternator on the right or left? 307 or 350 brackets? 2 or 3 groove pulley?


A 307 water pump will physically bolt up, but why run a smaller pump? There's a couple of different 350 water pump configurations.


Oil pressure gauge is from left side on the shelf above thetiming chaincover. Water temp is from the left front intake manifold. You can use a 'T' to keep your idiot lights, too.
