replacing m715 engine
Post by fhozaly on Nov 1, 2006, 5:34am

please if any one have an idea please help

Um, Sir, Most of us have no car's here. However, the 8cyl GM engine fits nicely into our trucks.

A 350 with the 465 trans behind it is common and painless. Relatively(sp?).

Look in the Modified board for information on swaps like this done in the past 6 months. Wait a few weeks and the online Manuals will be available again. There you can read about this kind of swap done over the last 8 years.

It is cheaper to find a complete 2wd truck engine and transmission. Then put them in the M715 as a unit. Depending on the engine, just motor mounts to make the engine fit, fabing a very simple transmission mount and maybe a little size adjustment for the short shaft to the t-case. I drove my 230/T98 powered truck home from work on a Friday, pulled it out and put in a 396 Big Block/NV4500 and drove the truck to work on Monday. The hardest part of the swap for me was the exhaust system.

One of our members makes a kit that will adapt a Chevy V8 engine to the stock transmission and believe it even comes with motor mounts. It seemed to be a complete kit (meaning everything you need) and, while a bit expensive, was actually quite reasonable compared to similar kits.

Post on the "Wanted" board that you are looking for anyone with a kit like that and I'm sure you'll get a response.

Good luck!

P.S. Where are you from?

My truck was adapted with a novak kit it left things a little crowded at the firewall. It's only a 305 chevy but doesn't want for power.

After repoering my M725 with a 350 to the T98 I would change the trans also to an overdrive to drop the rpm's and increase the gas mileage a bit. 6-7 mpg with stock T98 at $2.00+ per gallon, ouch. Really want to go diesel.

Has anyone looked into swapping in a 6.5 Turbodiesel?

4 or 5 post up is one by Sermis. He did the Novak kit on his 725. But, as he pointed out. he is getting mid single digit fuel milage with the stock transmission. I put a 396 Big block and od transmission in and I am getting low double digit milage.

Plus, for the price of the Novak kit, you can get the transmission that was behind your new engine or most of the price of a NV4500. That is a better deal in the long run.
installing a bench seat advice

I stuck the battery under the hood during the re-wiring process of this M-715 with w a 6 cyl ford truck motor. I purchased the truck in Auburn In. recently at the MVPA show for 1200.00. I would like to put in a bench seat and am looking for a posting I saw recently on this topic. The guy even had pictures which I would like to review. Please advise if I can still access this posting or if you have advice for me.

I am selling everyting else that I own with 4 wheels . This is one tough vehicle.
