56" is a little narrow for a YJ frame. It would be perfect in a CJ7 frame, but he won't get full turn in his Jeep.
Yep, didn't think about it being a YJ, the 86 and up axles are 60, which is YJ I think, no solid front though, one would have to space a mini truck axles. All just discussion at this point anyway he is well on his way with the 44s. I bought all the new parts to build a high pinion and picked up a 4.56 cyl chunk for the rear last week. Also got a high steer set up using one ton stuff. Pulled the T-4 to make way for the 435 today. Well on the way. I would replace that frame if it were me, but if you are gonna build it do a fully articulating 4 link or something exotic.
Careful, your character's showing!

Dang Dave, might be easier to pick up a few sticks of 2x3 channel and build new frame rails

I tend to agree. The frame measures 4" x 2-1/2". The bad spots are after the rear leaf spring mounts. It's certainly fixable. I'm confident that she'll be as good as new when I get done with it.

Well that goes without saying.....just thinking of options.....if it were me, I'd be looking into having new frame rails bent up to copy the originals in m/s tubing, then add brackets to the stock locations....functional, lightweight and cool

The local Alro Metals store has in stock 4" x 2-1/2" rectangular steel tubing in 11 gauge, which will be a perfect match to my frame. The decision is made, I'm going to chop the back end and rebuild the rails. I'll make the fish plates in the shape of pentastars, just because! I'll also fab a new rear crossmember/gas tank support.

or a new frame
That's taking the easy way out, and the expensive way out, too. I bought a 14 foot stick of 4 x 2-1/2 x 11 gauge steel tubing, plus some 11 ga. flat stock for the joiner plates.

You can hog those magnum heads out some for sure. This is the best pic I could find at the moment. There is a large restriction in the bowl below the valve seat. You can see this comparison on the 2 Magnum intake valves pictured. On a well ported Magnum intake throat, a golf ball will snugly fit all the way in the port and sit on top the valve guide, where it will not even closely set that deep on a stock port. Don't mess with the short radius that much, but the other 3 walls of the port should pretty much go straight down from the valve seat, eliminating the bottle neck.

The new magnum heads came in. With these heads, the 390 should make great torque down low.
Dave.....you mention new...??? Are those stock magnum heads from Ma Mopar or aftermarket..???
318/390...cool to see your going to stroke the 318....who's crank, rods and pistons are you going with...???
I remember "mild 318" being mentioned in your 1st post....funny how plans tend to escalate.....it's a sickness....lol

That's some great porting advice, and I really do appreciate it, but my goal (for this application) is making good low end torque, not big HP numbers. I'm looking to make around 300 HP, which will be plenty for the Jeep, and from what I've read, the stock heads are supposed to support up to around 400 HP.

I bought the heads from a Moparts member. They are 10 year old factory heads, so they aren't "brand new", but they were never used on a running engine, just used for mock-up purposes on some engine builds. I looked at them closely, and I see no evidence that they've ever been used.
I'm going with an Eagle cast 4" crank, stock rods, and KB forged pistons. I wish someone made hypers for this combo, because I don't really need forged slugs in this application. The KB's are the least expensive pistons I've found for the 4" crank combo.
The extra cubes are tempting, because it doesn't cost that much more to go from 318 to 390. Big torque down low is what I'm after.

Dave, When you get ready to order your engine parts, check these guys out. www.cnc-motorsports.com Right now they have the Icon 390 pistons for less than $370 a set ($475 at Summit!). Also, there sure has been a lot of buzz here on Moparts lately about the Eagle 4" cast cranks breaking even in lower horsepower situations. Same folks above sell the SCAT 4" cast cranks for about $300. LOL I'm not a Rep for CNC, I've just bought some stuff from them and been happy with the prices and the way the transactions went. Just my

I'd go with the Icon's....nice pieces and the price is right....our 408 has a Scat Cast Crank, Scat I-Beams and Icon Flat-tops.....you must have a deal on machining because the cost resizing stock rods with new bolts is usually damn close to what a new set would cost....
Should be a sweet moder

Just Throwing this out there... Right now Mancini has the Eagle SIR rods in the pressed pin version only, for $130 a set...
Edit: Oh yeah they're in the "overstocked" section.
