Re: 1991 chevy v3500 3+3
The engine is just a GM Goodwrench new crate engine. It is only rated at 200 HP with 300 Foot Pounds of torque. The heads are center bolt swirl ports. The compression is 9.25:1. I did take the stock cam out and put a mild COMP computer controlled cam into it (PN# 12-304-4).
I also bought a bored out TBI from VIC Morse, with an adjustable fuel pressure regulator. I had the stock aluminum intake bored out to match the TBI. I added a 5-QT oil pan to it as well, along with a steel sleeved oil pump drive. I will get some mid-length headers for it in the future, and do some custom tuning to the OBD-I ECM as well. all of these mods should add another 50 HP, at least, to the stock engine output. |

Re: 1991 chevy v3500 3+3

Re: 1991 chevy v3500 3+3
Yeah I am using a tci stand alone unit, it has been flawless for years. I was fortunate enough to find a 91 trans and tcase, it has been awesome.
