comanche13 Posted December 22, 2009 Share Posted December 22, 2009 i found a comanche with a 4cly and 4.10 but i want to take the axles and stick them in my truck and stick the other ones in the other truck but will the 4cly be to gutless with the 3.09?

Darren Posted December 22, 2009 Share Posted December 22, 2009 A 4 banger with 3.07's would be gutless. Like less than zero power. But if your going to sell the truck then who cares right? Link to comment Share on other sites More sharing options...
Automan2164 Posted December 22, 2009 Share Posted December 22, 2009 The upper gears, if not all, would be useless. Rob L. Link to comment Share on other sites More sharing options...
comanche13 Posted December 22, 2009 Author Share Posted December 22, 2009 well no i was hoping to keep both so i can work on mine because right now i can't do any work on my truck for i wouldn't have a vehicle to drive. Link to comment Share on other sites More sharing options...
freakjeep93 Posted December 22, 2009 Share Posted December 22, 2009 if you don't mind driving with you foot on the floor all day then 3.07s might suit you. but no 4 cyl and 307s don't mix Link to comment Share on other sites More sharing options...

It would suck, but be drivable. The 4 speed 2.5L MJ's came with 3.55's, and the one I had did pretty good on the low end, but I could not imagine what 5th would be like in something with 3.07's.

mnkyboy Posted December 23, 2009 Share Posted December 23, 2009 I'm currently running 2.5L/4spd with 3.55's and 33X12.5 tires, Its not a rocket but it is way more powerful than i had expected it to be. with that said i can't wait to get new gears on the street with stockish tires i think you will be fine at least 1st through 4th gear. i don't think 5th will be much use as my 4th feels about how 5th should.

carnuck Posted December 23, 2009 Share Posted December 23, 2009 Put really low profile tires on it and it'll be fine! (smaller tires are like lowering your gear ratio) Link to comment Share on other sites More sharing options...
pingpong Posted December 23, 2009 Share Posted December 23, 2009 I have the 4 cylinder with 3,55's and it is aq dog with 31's. I do plan on swapping in some 4.10's once I find another front axle. Link to comment Share on other sites More sharing options...

COMJNUT Posted December 23, 2009 Share Posted December 23, 2009 Put really low profile tires on it and it'll be fine! (smaller tires are like lowering your gear ratio) Do that, it's easier and better for your situation. 4cyl and 3.07 gears is a bad combo, 1st and 2nd will be your friend, any further than that...no dice.

WBKrazy Posted December 23, 2009 Share Posted December 23, 2009 in a race between an mj with a 2.5 and 3.07's and a 1982 craftsman 15hp lawn tractor, it'd be tough to guess who the winner would be... :dunno: i know mine with a 2.5 and 3.55's couldn't even beat a 1.6L 4spd. toyota tercel Link to comment Share on other sites More sharing options...

deziped Posted December 24, 2009 Share Posted December 24, 2009 2.5, 4sp, 3:55,s, & 235 X 15's is the reason my daughter now owns it, My old MJ that is. It couldn't get out of it's own way at intersdectons Link to comment Share on other sites More sharing options...

Rob L. My 87 4x2 w/4speed and 2.5 runs at 3,000 rpm at 70-75 and does very good there. I do have a Delta cam with a bit more lift and duration and Cliiford header with a Flowmaster single in/dual out that adds probably 15 hp. On a flat road I can, without mashing it to the floor, make 60 in no more than 10 seconds, and can easily pass in 4th when someone is only doing 50-55 in a 60, so I cannot imagine running about 2,000 at 75 and a stock 2.5 and what that would mean. Would be gutless. Link to comment Share on other sites More sharing options...
