" From: "Rhett Butler" <amc.inline.six@xxxxxxxxx> " " " " I'm more after economy, and so I don't plan on going for an engine swap, " unless it's advantageous in that way, or unless the engine tires out. if that '77 grem has an auto or sr4, you could swap an amc 4 in pretty easily. the motor mounts are pretty far forward on the block and i wouldn't be surprised if they're in the same place as the six's, though i don't actually know. for the sr4, you'd also need a bellhousing from an amc-4 jeep with a t4 or t5. come to think of it, this also might work with the grem t150 if amc-4 jeeps were ever available with the t176. a '94-5 gm s-10 2.8 bell might also work. for an auto you'd need the tranny from an amc-4 jeep, like a wrangler, and you'd probably have to swap it back to 2wd with the tailshaft bits from your grem's tranny. if you do a lot of highway driving and the grem has a 3sp, an iron cased side shifter overdrive toploader from a ford granada or i think also pickup is a straight swap length and spline wise. it obviously won't work with a column shifter. likewise, the sr4 could be swapped for a t5 almost as easily. " A 4.0 in a Gremlin or Eagle would be awesome at that point. if you can keep your foot out of it [;^>] the 4.0 would also give you better mileage... ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
