4.0L HO Jeep Engine Build

That girdle is actually pretty darn stout. IIRC, it's over a 1/4" thick and has quite a bit of heft.

If I were you, I'd take that 4.2 crank and drop it in a late block (they're a dime a dozen at the bone yard) and make yourself a 4.6 stroker. :) The main cap bolts for the girdle are different and do interchange among the 4.0's but I don't know about the 4.2's. Oil pan clearancing my be necessary too.



Glad I could help someone here, that's the idea. 8)

I was more interested just for the sake of knowing. I guess it's just that the girdle doesn't look like much compared to the one I bought to use in my 408. My completely rebuilt 4.2 has been finished for at least a couple of years & sitting on the engine stand while I keep nursing along the car with the engine it has now. Still need to iron out a few things to make the EFI work in my '86 car. Meanwhile, the other mechanicals on the car have me busy just trying to keep the thing on the road. :-D
