hmm, still sounds like the 6 gets better mileage then a 350. Even when mine was still in good shape it never did better then 12 mpg. Thats with 3:73 gears and 31 inch tires, auto etc. I bought the 292. The guy was selling it cheap but I tried to knock a few bucks off by commenting on the leaky front seal etc. And he was like give me a hundred and I pull it. Done deal
The best part is he is letting me take all the brackets and mounts as it is coming out of a 71 truck. Anyways, the motor has a single barrel carb that looks like its seen better days. I have decided that since this motor is going in I am going to invest in a gasket kit and a exhaust and intake upgrade. I do not plan on trying to build massive power but I think a 2 barrel and a header would help. was there a factory 2 barrel intake that will bolt on? If so what truck/ car would be the place to look?
