Stroker Or Hemi ???

I've thought about the hemi swap, but I think that's wayyy too much money just to be able to say it's got a hemi. SBC I think is the way to go...

Stroker is a waste of money, IMO... Now if you did the stroker, a Hesco aluminum CNC hi flow head, cam and roller rockers then you'll have something!

I'd personally add a little compression, 8.8 is pretty low, 9.2-9.5 would be better. ->sbc may be cheaper then re-building the 4.0

This is what I am doing, but no Hesco stuff. I have a cousin that hand ports heads and flows them for circle track folk. We are working on the best numbers for the 4.0 with a custom cam and roller rockers. I am also doing the new AEM, I believe, (I'll have to ask Jimmy who it was again) Jeep computer.

I am only going this route for my sheer cheapness.

I have a Northstar that would be really bitchen in a TJ....

The biggest problem with the 4.0 is the head. Casting 0331 is junk and is very well known for cracking. The head also doesn't flow well, it creates hot spots in the cylinder (pre detonation/ping!), etc. It also has thin water jackets and runners. All of this is the reason they are very ineficient and have high smog numbers.

If you did nothing else, you should at least get the Hesco head. They've addressed all of those issues....IMHO...

I hear ya.. But I need to figure out what it will cost to fix the 4.0 I have now first. I mentioned to the wife yesterday that my motor might be shot, and the first thing out of her mouth was that I don't need the Jeep! She needs furniture!! And then it went into a b!tch session about me only thinking about my Jeep and never about her and how much nice furniture we could have with what I've spent on the Jeep over the past 6 months She's right, but:-\

BTDT, and you'll never win that argument. Good luck. That's why I'm without a buggy and slowly building the TJ.

Please post up what you find out. I'd love to get a little more punch out of my 4.0L with out breaking the bank. The HESCO head is nice but wat over priced. Once you add up the parts the SBC would be cheaper.

I think so, too... That's why if I have to do anything, I'll go the SBC direction.... :-\

The most I'll put into this motor is a re-ring kit ($30), some new main/rod bearings, a gasket set and some minor head work/used head. ...And thats only so I can get it back on the road until the little lady gets what she wants Gotta keep her happy. When she is happy I can have anything I want (and she's buying kinda thing). But when she's not happy....:-\:sick:
