MPG question

(1/4) > >>

Mr. Machanic:
Yes, this is probably one of those stupid questions similar to "what's it worth".
So forgive me now...thank you.
I'm just looking for an approx. baseline.

About what would one expect for mpg.
78 Big10. 6200lbs. (6400lbs with me in it)
350ci with 350 auto.
Original QJ. HEI on rotor.
New plugs.
GPS shows 5 mph faster than speedo.
I don't have a tach, yet.

Currently getting 10 mpg on 87.

Thank you.
And Happy New Year to all.

Mr Diesel:
10 is about right I think. 12 is about max with that setup. Everyone exaggerates their mpg...

Mr. Machanic:
Thank you Mr. Diesel.

Honestly, I was hoping that 15mpg would be obtainable.
But I think that would need a different tranny and rear end.

zieg85:
15 is achievable IMO.  Several factors have to line up.  Easy driving is the main thing.  Optimal tune is the other.  I find most issues are with inadequate timing due to advance not working the way it should. 
 

Mr. Machanic:
Zieg85,
Thank you.
I will keep timing in mind.
I am making a list over winter of things to address when summer hits.
