I inhereted a 1991 K5 from a friend who bought it a year ago. It has a very nice body, and great interior, and the interior was totally replaced a year ago. The only trouble is that he never every checked or changed the oil, and totally ran it dry and ruined the motor. He decided that he'd enlist my help to pull the motor and rebuilt a new one. After we pulled the motor and exchanged it for a new short-block, he decided he'd rather just get rid of the truck instead of messing with it anymore. So I decided to "Help him out" and buy it from him for practically nothing. I've built a few 350s before - I built one for a 74 Camaro, a 75 Camaro, and a 86 Firebird, but I've never dealt with TBI before. I'd much rather skip this TBI stuff and convert it over to a carburetor, but I'm leary of doing this with a block from 1991 because I was unsure of how to deal with the EGR and how to wire up an HEI distributor. The rest I think I can deal with, but those two have me stumped. Should I stick with TBI and try to figure it out or is there a way to change the distributor over to an HEI?
