20 plus mpg 715

majortom · Jul 12, 2008

I have built many v8 715 trucks over the years. my personal truck has a 400 plus hp small block, 4 speed, 900-20,disc pb, ps, and dumps. Goes like H, at 6 mpg. So the future of fuel prices means i have to do something. After much thought, and beer, i decided to repower one of my other trucks with a 6.2 / 700r4 as a test. we did a bare frame rebuild with the goal of fuel econ. and comfort. Six mounths later, super seven was born. I average 20 mpg and can cruise at 70. There are detailed pics on alfaheaven.com if you want a 715 that is useable in todays cost issus, this combo works.

I visited your site but couldn't find the diesel 715. I DID find some excellent trucks tho. I may have to make a roadtrip! :wink:

Nice. I wonder what MPG Spicer got out of his GM diesel M715 swap he did a few years ago?

Dang thats one clean M715! Wow great job! Gotta love the old kaisers! Sweet looking rig and 20 mpg should make it a lil easier on the ole wallet!

Not 20mpg. Hell, the stock GM trucks didn't even get that. I call shenanigans.

That kind of what I was thinking...

Put a 4BT in it if you want 20+mpg.

Elwenil · Jul 28, 2008

We have that covered too, lol. McInfantry put a 4BT in his M715 but I don't recall if he mentioned what his mileage was.

Nice work, an inspiration.

I have a 1983 J20 (M715's civilian cousin) that I am rebuilding from the frame up after it was stolen and wrecked. I'm hung up on a bent rear axle housing right now, a Dana 60 with limited slip. I had the original AMC 360 cui rebuilt and balanced. I'll be happy with 16 MPG at 50! Time will tell.

Lanty, he said 32mpg with nv4500 and 4.56

docfarmall · Jul 28, 2008

hum i still like my 50 mpg duece

Elwenil · Jul 28, 2008

Thanks Gimp. I searched a bit over at The M715 zone, but it's almost impossible to find the old info over there now. I knew he had a better shot at getting impressive numbers with the 4BT, 5 speed and the CUCV axles.

gimpyrobb · Jul 28, 2008

You will not find his info on the zone. He decided to delete his posts on there.

Elwenil · Jul 28, 2008

Ahhh, I forgot about that! For some reason I was thinking it was one of the other guys. Too much drama to keep track of, lol.
