inline 6 and 3 on tree
 

hey guys, i have just bought a 1977 c10 with what i'm guessing original engine and trans. i want to know what are the stock specs of my combo for a 1977 c10. i've tried researching o google but not really coming up with results. i would like to know hp/tq/mpg . any info on stock performance is great. stock everything.

i think i've found my info that i was looking for on hp/tq. a general ball park figure. but i only found one source that stated they got near 20mpg. is that possible?

maybe on the highway but i never got better than 12 or so with mine.. bear in mind i live in the city tho..... the other thing that was a pain on that truck was the arms kept locking up and youd have to pop the hood and knock the linkage into neutral lol
i do not miss that truck!

If your easy on the gas 15+ mpg city should be easy, the highway mpg depends on your gear ratio, tires and speed youll go. 155HP at the crank according to wikipedia. Monsterous. :)
