The V8 sits in there nice. ps wouldn't be the problem. it's all on the side of the block. the 4.0 serp belt setup hugs the block even tighter than the '65 american v-belts; i wouldn't be surprised if you gained an inch, and that's enough for an a/c condenser isn't it? " > Jim Boone " > Mims, FL " " My two cents worth: " " Don't use an overdrive, more parts spinning around will use more fuel. " Use the Warner Gear aluminum transmission, if you must the 998 allows " the lockup convertor and a lower first gear. AMC 7&9/16 axles can be " had with 2.35:1 and 2.37:1 ratios. also 2.21, 2.53, and 2.73 " There is no point in using extra gears to spin the drive shaft and " pinion faster so that it will turn the ring gear the proper speed. that's fine once you're moving, but a lower overall first will help mileage in stop-and-go, not to mention starting on hills. if you do a lot of that the tradeoff is worth it. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
