I would hate driving my jeep with 4.88s that's way too much gearing for me. 4.56 would be okay but I would suffer on road trips

Ive been absent awhile so forgive me for repeat info but what axles are you turning 5.13s in?




Edit: just scrolled up and saw "Rubicon"...so I'm assuming Rubi D44s ?
He's running 60s iirc

If your only goal is to make HP cheaply, yes, swapping in a higher HP motor to start with - especially one with a massive aftermarket like an SBC or LS - is the right choice.

However there are plenty of reasons to not just drop in a small block v8. Number one, everyone does that already to everything so whats so special about it?

I like to keep it in the family, I couldn't in good conscious take a Jeep and put a Chevy motor in it. I have a 351 windsor short block hanging out in my garage that would fit great, but same issue, that needs to go in a Ford. (if we are talking about a vehicle I am not passionate about, maybe my opinion would be different).

I also have a love for straight 6's: They run so nice, they are tough, easy peasy to work on, excellent low end, etc.

My goal is not to make the most HP as cheaply as possible, I want to make plenty of power, have a really fun jeep to drive, and have fun in the process. That in addition to the above points is why I have the original straight sixes in the jeeps. Plus both of my I6's are already stroked to 4.6L and make similar HP and more torque than your stock V8 does anyway.

So throw 10psi on top and it should be that much more awesome.
I am looking at it purely from the reliability stand point. A 4.6 with a blower will be less reliable than than a stock 6.0L if you abuse it. My jeep is a daily driveable one ton xj on 40s that is on its 3rd stock 4.0L they have a bad habit of making holes in the cylinder walls no matter what mileage the motor has been. The 60k mile motor exploded quite spectacularly taking out the lower rod bearing and windowing. The og motor from the jeep ate the crank and the current motor is on borrowed time as I am not paying anything for another 4.0L. That is why I ask I have found them to be less than happy with the level of rev limiter that gets applied trying to warm up 40s. My buddies with stock LS family engines just wheel.

33x10.5x15 with an ax15, 5th gear is all but useless unless I'm on flat ground

Ok well in that case I'll just bounce. I redownload tap talk and it has my old password saved so we are like 3 jeeps behind the curve.

kluttsy01 Gave it a bath yesterday (and it is raining today of course) just got home from the alignment shop and she drives sooooo much better. They said it was 3 degrees out of wack, now it feels like a completely different jeep. Currently contemplating regearing to 4.10s or 4.56s.
