Hi folks,
I've been having a bit of a discussion with exlimey over some tea and scones regarding the MPG's in our 250 CI straight 6 engines.
Exlimey is running with a 250 mated to a 2-speed Powerglide, and gets around 14 MPG.
I am running with a 250 3-speed manual and seem to be getting around 22 MPG. I don't have a tach in the '67 but I'm guessing it's around 3500 RPM at 65 MPH. That's just from counting.
Any thoughts on the gear ratios between the two setups? I'm thinking he's pushing 4000 RPM at 65 MPH (not that he can go that fast in the UP of Meechigan). Me thinks he should be getting better mileage with the 250 6-cyl - but maybe it's stop and go cruisin' up nord. Brrrrr! :devil:
Thanks for your thoughts mates.
Cheers, Tim
