tell me about inline six/I have some question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I had an L6 in my truck (250) with a 3spd Muncie tranny on it (3 on tree). I seriously averaged less than 7mpg with that setup on 3.73 gears.

I will tell you this, though: That damned engine was the easiest thing EVER to work on. There is literally almost nothing that can go wrong with it. Upgrade the stock points ignition to HEI ignition and it starts every time like clockwork (one tap on gas, then turn it over and BAM! it was running).

Bad part: good bolt-on headers that FIT well do not seem to exist. Tolerances are very tight in there. There are good bolt-on intake manifolds out there for the L6 though. 292 seems to have a lot more options, and more potential as well.
