Install a mild cam, free flow exhaust and the fuel injection setup from an 91-95 Jeep and you'll have a real performer. And even cheaper, if the 258 you've got is in good repair, go to a 'yard and get an 1980's aluminum intake and matchin exhaust manifold, and a Jeep Weber conversion, or a 2bbl-4bbl adapter and a Holley 390. Put Duraspark II ignition on (also mostly junkyard parts), and the biggest exhaust you can fit (even if it's neck up from the downpipe -- overall restriction will be vastly improved) -- and you'll have DIRT cheap performance. Won't touch the stroker though for HP of course. The 904 (almost certainly what you've got) will be just fine under it. _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
