If it were me, using the drive train already in my possession would almost be a no-brainer. I'm kind of a Chevy guy and I'm a huge fan of the LS engines...but there's no denying the reliability of the 4.0, not to mention the drivability of the AW4. Mate those with some JK axles and the right gearing and you'd have a winning combo. You could always do an LS build in the future. Of course my opinion is skewed, running a 2.5L I'd have a hard time being unhappy with a 4.0.

Sometimes a good reliable setup is better than going for what's cool. However, if you think you will be unhappy without an LS powertrain in this jeep then I say wait and build what you want. Depends on how long your willing to wait for what you want vs getting this thing on the road quickly.

When he gets the bed set on the frame he will be as anxious as a little kid on Christmas morning to get this thing on the road.

Yes, that is what is bad. The bed is nearly ready. And the cab could be ready for paint in a few hours. So, with that. Saving up for the 6-10 k to do a LS swap or rebuilding what i have on hand.

Well you could rebuild what you have and save up for the Ls swap when the time comes and sell the 4.0 and aw4.

I vote for this! http://www.ebay.com/itm/2008-Chevrolet-Trailblazer-SS-LS2-Engine-Auto-Transmission-AWD-6-0-Liter-32k-/140619863455?pt=Motors_Car_Truck_Parts_Accessories&vxp=mtr&hash=item20bd98d59f But as said above if you already have a 4.0L and AW4 maybe install them for now and upgrade later.

Going next Saturday to pick up the JK44 for the rear. He says he also has a JK30. I may see about picking that up as well.
I've got a hook up on a 4.2 out of an early YJ. Can get a hell of a deal on the whole thing, let me know if you are interested in the crank and rods.

Still not sold on the longevity of a stroker. If this was a trail rig only... Maybe.

But, I want to be able to put a 15-20 K a year on this rig with little problems at all.

High compression or getting crazy(like what I'm building) is the only reason I can say that you couldn't make one just as reliable as a 4.0, and there are several low compression/low dollar engine recipes.


4.6L "poor man's" stroker

Jeep 4.2L 3.895" stroke crank
Jeep 4.2L 5.875" rods
Sealed Power 677CP*+0.020" bore pistons
9.25:1 CR
Stock 4.0 camshaft
Ported HO 1.91"/1.50" cylinder head
Mopar/Victor 0.043" head gasket
0.088" quench height
Ford 24lb/hr injectors with stock 39psi FPR for '87-'95 engines,*Accel 24lb/hr*injectors with stock 49psi FPR for '96 and later engines
248hp @ 4900rpm, 306lbft @ 3250rpm ('87-'95 camshaft)
245hp @ 4800rpm, 315lbft @ 3000rpm ('96-'06 camshaft)

NEW: Modified "poor man's" stroker

Same as above except Jeep 4.0L 6.125" rods, Keith Black UEM-IC944-020 forged pistons, and 0.070" quench height. This is a great stroker build for a mild supercharger/turbo application with up to 6psi of boost. The 4.0L connecting rod/IC944 piston combination offers 155g less reciprocating mass than the 4.2L rod/677P piston combination (1275g v 1430g), thereby giving this engine a potentially higher rpm capability than the traditional "poor man's" stroker.*

If you don't have the funds/time/inclination to do the LS right now, toss what you have to get it on the road. Even with a I6, it will still obviously be unique and cool. When you get tired of it, a LS swap could make it fun again.

That's what will probably happen. Then add the bling later.
