Need Opinions/Advise

[badinfluence]

I am wanting to put a cummins 5. 9 motor in a 72 chevy 3/4 ton 4x4, but I am wanting to build it to truck pull and mud race, I would prefer to stay away from electronics, what I need to know is what year of motor would be best for this? Which injector pump is best etc. etc. I would like to use a turbo 400 transmission. Does anyone have adapters for this ? I want to make lots of power. Any input on this would be greatly appreciated. Thanks in advance.

96 and newer 12 valve with 5spd trans is a 215 hP rated motor. With auto trans I think its 180. Stay with the 96 and newer as the P pump on these engines need the least mods for max HP

Supposedly......

You can buy the adaptor from the Chevy dealer to put a 700R trans behind a 5. 9. I do not know this for a fact, but Manual from Brannex Truck Salvage (505-877-4244) in Abq says it's so. I think the pattern is the same for a 400, so you might check it out.

A better way might be for you to find a 727 or possibly a 518 (if you want OD) Dodge transmission mated to a NP205 transfer case. Manual does have one of these setups, (a 727) with a gear vendor overdrive unit on it if you are interested. I understand these are just about bulletproof (the 727, don't know about the OD unit) if built correctly.

Dodge used the 727 from 89 to mid 91, and the 518, from mid 91 to the end of 93, I believe. I am not sure. I also think another name for the 518 is a 47rh, but again, I am not sure. I am sure, if wrong, someone will correct.

Do a search for "conversions" and "Chevy" and it should bring back a few postings about Randy Bleuth in Prescott, AZ who has done a number of conversions. He probably knows as well as anyone what to look for, and he can sell you some prefabbed motor mounts for your truck.

Good luck on your project. Are you married? If so, we can induct you into the POW club before you start spending all the grocery money for parts... .
