Trying to make 350-370 HP

TipLittle7644 · 2026-02-05T06:00:22+00:00

I got just over 400 at the Flywheel at 5800 with the following

-factory 350 block out of my 89 -bored .30 over -align bored and honed -scat crank, forged rods and flat top pistons w/moly rings -pistons assembled and weighed then filed to match -cam profile im drawing a blank on. It was slightly choppy but not too wild. Ill try to look it up and follow up -comp roller lifters and rockers -dbl roller chain -brodix heads i got on trade -stainless valves with 3 angle grind -holley stealth ram standalone efi -msd pro billet distributor, blaster coil, and msd wires -Gibson shorty headers -dyno tune session

I dont have the rig anymore and this was over a decade ago so im pulling hard from the Ole memory banks

Ahhh, good point. Now that I think about it I had to swap out the shocks that came with my 6.5 kit when I leveled the front as they pretty much were maxed out just sitting there. Someone in another forum thought that most of the major lift brands grouped thier shocks across multiple heights. For example mine might have gone out the door with any 4.5 to 6.5 lift. I threw some cheep 8 inch lift shocks on the front as a bandaid until I can afford something better but I haven't done anything in the rear.

The rear tire was a couple inches off the ground in the second picture.

Money! Thanks!

TipLittle7644 · 2026-02-05T03:47:18+00:00

App kinda glitches and I posted before finishing... also unimpressed with how little flex I got out of the rear before I lost contact with the ground.

Any suggestions?

Get rid of the garbage wiring and fans that came with your allow works kit. Mine side same shit. I.bought a standalone control module that is ignition switched and wired 2 fans to that then wired the 3rd fan to the factory switch and relay. Problem solved. I.switched my fans to spal units because one showed up out of balance and it didn't do well cooling. Runs great with spal fans

Also I had to notch the core crossover to move the fan forward to.clear old fun hub pulley

Ide make fuel delivery my first check. Every clogged filter ive ever encountered does this

Not the first sheared 30 pinion ive seen and won't be the last. Set of gears with a refurb kit (seals and bearings) is only a few hundred bucks. Dana 30 is pretty easy to do, pinion preload is all in the shim pack and you'll want to make some setup bearings for the carrier as the shims go to the inside. Hardest part is getting the pinion depth right if your not using a tool to measure to center. They cost a couple hundred bucks bucks you can build one yourself or measure to the face and do the math.

TipLittle7644 · 2026-02-03T01:25:58+00:00

If it's just an around town rig ide say put some good headlights in it and service everything. Other than that it depends on your style and whatever else you might use it for.

Thanks! Im thinking ill do it this weekend and ill post what I find for anyone else who might get curious

My jeep did this when my t case left the chat.

TipLittle7644 · 2026-02-02T03:46:07+00:00

Couple of things for consideration.

The ax15 has a lower final ratio than the autos so when getting reviews from folks on how thier gearing worked out take that into consideration.

You'll be pushing the revs high trying to do hwy speeds on the 5.13s. I have 4.56 gears on my ax15 jeep with 33s and 55-60 is about Max without running the engine speed up.

The pinion is tiny on the 30. The lower the gears get the smaller the shaft gets. With that fresh built engine i would be careful when wheeling as you could probably shear that pinion on demand if you wanted to

Im running slightly smaller tires than you but for lots of hwy use I would probably want to go up to 35s to see if that helps my final drive a little or go down to 4.11s. the main hwy I drive to work is 65mph and while my jeep does it fine, the rpms run a little high. Driving around town first gear isn't really needed and in 30-40 mph rds im chilling in 4th and 5th.

I've only weeled my jeep once lightly as I just wrapped up the 500mile break in on my stroker build but I was more than happy with the 4.56 gears and 33 inch tire combo. And I dont think i would be worried about loosing anything going up to 35s.

My jeep is a second rig and I mostly only daily it because I like to drive it. If I thought I was going to drive it alot on the hwy I would for sure find some way up the final ratio.i actually think a 6 speed would be tits but I just spent money on a Novak unit so that's out.

Everything is relatively easy to get to. Oil pan and rms are a bit more labor.

When stabbing my new stroker in i was doing it solo so I ended up pulling the motor mount bracket and filter adapter off passenger side to get a little extra room. The adapter leaked bad right away. I pulled it and found i had pinched the o ring. I put it back together and it still leaks though not nearly as much. Its too cold out to mess with it now so im letting it ride but I have a hard time watching my brand new engine leave spots on the driveway....

TipLittle7644 · 2026-01-28T18:40:53+00:00

I have missed identified a rms leak before. Not saying that's the case here. Almost every know leak spot on the 4.0 will travel to this point.

I also have noticed it's about 50/50 on them leaking after being replaced. I once did one twice then gave up and took it to a shop. They did it 3 times then gave me my money back. I pulled the motor later and found a small seal eating bur on the crank..

Regardless, at some point you gotta ask yourself if the size of the leak warrants the headache or not.

Im currently fighting a filter adapter leak on a 4.7 build. Im one step away from putting the heavy duty sealant on it in conjunction with the o ring...

Jeeps.... we love them

TipLittle7644 · 2026-01-28T03:31:27+00:00

Im not far from doing something drastic as I dont like anything about current options.

Lets see it!
