Me and my dad had just gotten done rebuilding my Chevy 350. I had invested the money in buying a comp cams, thumpr cam. When tearing into the engine I had to have a valve job done on the stock cast iron heads. I did install a new Mellings high pressure high volume oil pump to help out with the cam. The truck also has stock pistons, distributor, crank, and tbi. We have had my truck running quite a few times before, but every time it had been unsuccessful in its idle. We have tried adjusting the distributor to set the idle but it seems to have no affect. My dad had suggested that I make the switch to an HEI distributor to eliminate the computer crap. I was wanting to know if the HEI distributor would be able to help my idle issues, or if I would have to also switch to a different tbi. The truck runs good while driving it, but once I let off of the gas pedal, it wants to bog down and die. I guess the other question would be if I had to adjust the idle on my stock tbi.
