Pontiac daily driver engine ?????
Im gonna try and keep this short.
1950 pontiac with '68 350/700r4 3.73 rear This is my daily driver I built a few years ago. I "refreshed" the engine but its pretty tired. Runs good but low oil pressure at idle. Here is where the question comes in. I have a good 400 that I could drop in. How would that affect mpg? Im getting around 17-18 mpg with mixed driving. I have a gen 4 5.3 that I had thought about carbureting and dropping in. I DO NOT WANT TO START A PONTIAC V8 vs. LS DEBATE. I simply was looking for opinions. Thanks |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
