At the time a chain and gears was less than $50; half a day later we would have a sweet running truck having paid only half what it was worth. They are thirsty devils but pretty much bullet proof if maintained.
Good luck,

the other thing you can do is advance the cam timing with an offset key. lots of old smog motors had late cam timing which kills low and mid range power. You should even get better gas mileage
