Correct, the Advance CPS kit used the stock CPS, which was why I ended up choosing it over the others. Very interested to hear about Wranglers with balancer-mounted CPSs from the factory. If true, that would be very useful. Yet another option is to find a 2WD XJ and use its transmission behind the 4.0L. That would likely involve trans mount fabrication, but it would provide a bellhousing CPS mount. dan Date: Wed, 31 Oct 2012 20:39:44 -0400 (EDT) From: adh@xxxxxxxxxxxxxxxxx (Sandwich Maker) To: amc-list@xxxxxxxxxxxxxxxxx Subject: Re: [AMC-list] Met a guy very interested in my '65 (OHC six) Message-ID: <201211010039.qA10diw16624@xxxxxxxxxxxxxxxxx> " From: "Dan Strohl" <DStrohl@xxxxxxxxxxxx> " " Rick- " " I've done the 4.0L swap into a 1979 AMX. My suggestions: " " [] " " * The 4.0L will bolt up to any bellhousing the 258 bolted up to, but the " bellhousings behind 4.0L engines had a mount for the crankshaft position " sensor, which 258 bellhousings won't have. If you're using a 4.0L " bellhousing, you're good to go. If not, you'll have to figure out a way " to mount the CPS. I used an Advanced Adapters CPS relocation kit, but AA " has apparently discontinued the kit since I bought mine. HESCO may have " a kit - I haven't recently checked. idle thoughts on this -- before about '03, the wrangler's auto was a 3sp closely related to the pacer's, and it has a cps mount. if you found a rebuild-ready core [eg. cheap] which would have to be disassembled anyway, you could have it converted back to 2wd and use it. nb. the obdII years are electronically controlled from the ecm. a cps relocation kit would be cheaper, but most of them - including iirc mopar's own - don't use the stock cps [read: costly, difficult replacement]. i thought advance was the exception. advance does have stick bellhousings with cps mounts, for various transmissions. they're about $375 even from discount dealers like forte's parts connection. you could hook right up to your existing tranny though. ps. i've known mike forte for about 30 years and he's a good guy and a square dealer. [btw if you have a 3sp stick, a swap to a ford toploader 4sp is easy if you don't mind a floor shifter] i've also heard rumors of wranglers coming from the factory with a balancer-mounted cps. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ AMC-list mailing list AMC-list@xxxxxxxxxxxxxxxxx http://list.amc-list.com/listinfo.cgi/amc-list-amc-list.com
