How do you convert throttle body to carb on a 89 Chevy Caprice?

Answer 1

you would have to get a carbeureted manifold and a non-computer-controlled-distributor. then you have a choice; you can keep your current heads and cut the four middle bolt holes on your new intake out to the edge so the bolts will fit, or you can put an older set of heads on it (older heads have bolts around the edge of the valve covers instead of through the middle). after you have bolted all these parts on with new gaskets, you have to run a positive (that comes on with the ignition switch) to the distributor terminal marked +. that should make it run, but your fuel pump will switch off after about a second. you will have to solve that problem by either wiring the fuel pump the same way you did the distributor (on and off with the ignition switch) and installing a fuel pressure regulator, or removing the fuel pump and running an aftermarket electric one or a standard manual one that bolts to the block. I am doing a swap of a 74 350 into an 89 scottsdale and i kept the serpentine belt system with the a/c pump, Power Steering, and stock 89 alternator. it is working so far, but i still have not solved the fuel issue for lack of money and lack of knowing which way is best. if you come up with any info on the fuel issue, please email me (benson-stacy@hotmail.com) thanks and good luck.
