Re: 92 tbi 350 rebuild or repower ?
Ok, straight wt 40 oil improved it to 35-38 psi warm hwy and 12-15 at idle so I know the tbi 350 is warn out. No surprise to me, it came without an air cleaner and very filthy oil but again, $500 1992-K2500 truck with an 10 month old/367x. mi goodwrench trans work order that started and ran out strong that was ok.
When I was talking about rebuilding the 95 parts truck 350 and putting in a cam I was thing mild RV type cam to help bottom end power a bit. No stroker, aftermarket heads or street/strip cam.
I have a good 98 vortec 5.7 4 bolt main in a bad frame/trans plow truck. Ideal would be to take that engine and the gmpp intake/egr valve and piping and exhaust to muffler and put it in the 92. I can see more fuel pressure but do I really need a re flashed ecm and everything else for a box stock vortec 350 to run with tbi?
