Mileage

[fbnwest]

A few weeks ago I helped an friend install an MSD 6A ignition, a new distributor cap, and some other odds and ends in his Jeep CJ-7. He's an engineer by trade and takes notes on every possible thing he does. Oil changes, miles per gallon (keeps the receipts), days and miles till next oil change, etc. When I visited yesterday and ascertained the vehicle was still running despite my help, he told me he had gotten between 1.4 and 1.9 mpg improvement. This made me wonder if there were any (relatively inexpensive) tricks to getting that extra mile out of your EB if you wanted to take that long highway trip. Thought I would ask here.

BTW I already thought of hooking onto an unsuspecting RV heading in your general direction.....

Think my sig has it but in my case it's a 1970 with a 302 and a 3 speed. 31" tires I think.

Great post...!

Prob. an argument coming but.., he prob. could have done the same thing by tuning/freshening up his old sys.

If in fact he's being honest or maybe babying his new sys. to justify.

Having said that..., they're (MSD'etc) great units.....just don't really come into play 'til high RPM's.

Your set-up is 'bout as good as it gets, for mileage...properly tuned that is.

There was no real consideration for mileage when these rigs were built. They're just "FUN"
