Druville Posted August 6, 2011 Share Posted August 6, 2011 So i was talking to my pops and he told me that he "needs to find a home" for an engine he built for the toy hauler suburban. Its a 383 small block chevy built for torque, he estimates 400-425ft lbs. i have a comanche with a tired 4.0. i was going to swap in a 5.3 but you can't beat free! so how long do you all think it will survive with the ax-15 otherwise i may just have to say bye bye to highway speeds and toss in an sm465, but then i know my stock axles with be toast with 400ft lbs low ratios and danas. I'm thinking if i leave smallish tires on it(31x10.50) it only has a 2 inch lift, and use it primarily on the street till i get a proper driveline i should be ok. what would you all do if you were broke and got a free crazy engine. i mean his engine guy said it could make 300 ft lbs at 1500rpm so hiding from the power aint gunna happen lol i just figure let the lack of traction be king and let em burn Link to comment Share on other sites More sharing options...
mnkyboy Posted August 6, 2011 Share Posted August 6, 2011 Funny,when I saw the title my first thought was you got a Toyota Stout engine. I was thinking,what the heck could you be doing with one of those and an MJ Link to comment Share on other sites More sharing options...
mvusse Posted August 6, 2011 Share Posted August 6, 2011 Stock NV 3500 and 3550 are rated for 300 ft-lbs of torque, but parts are hard to come by. Stock AX15 should be good to 350 ft-lbs (according to Novak), and they can be built up to 420-450 ft-lbs. They also adapt to a GM small block relatively easily. Either way, I don't think your truck has enough weight to use 300 ft-lbs of torque. Your tires will break loose before the engine gets there with the excess torque being "burnt off" with the rubber, so there shouldn't be an issue. Now if you go with 42" tires and front and rear lockers, THEN it might be put to the test. Link to comment Share on other sites More sharing options...
1990 Pioneer 4x4 Posted August 7, 2011 Share Posted August 7, 2011 Maybe find something else to put the motor in? Link to comment Share on other sites More sharing options...
Dirteatr717 Posted August 7, 2011 Share Posted August 7, 2011 Maybe find something else to put the motor in? Find a third gen Camaro or something, I picked mine up for 1k and it had a 9" rear already :P Link to comment Share on other sites More sharing options...

Druville Posted August 7, 2011 Author Share Posted August 7, 2011 i have a 68 chevy pickup we were going to put it in but its so far from finished and the engine is being stored at a friends motorcycle shop, and its just in his way. i was shopping for k5 blazers for awhile. but i really don't have the cash to purchase another project right now. :/ i wasnt even going to go v8 in the comanche till it had a big lift and strong axles but it just waiting to go in something. bad timing i guess. i can finance some more peices b.c i have a 95 xj parts truck but thats pretty much my budget on this build is what i have in extra parts on craigslist here and ebay heh. i was thinking about going ahead and bitting the bullet to get a novak radiator b.c it is a $3500 engine and id feel real bad if i grenaded it. probably throw some vents in the hood too, maybe do a home made cowl in it as well. heck i never actually use it as a truck i could do it baja style and toss a radiator in the bed. get a long travel suspension and complete the look. I'm really on the fence on this one. i know as it sits it be one hell of a sleeper on the street if i could feather it up through 1st, maybe bolt on a set of old traction bars i have laying around lol Link to comment Share on other sites More sharing options...
