Depends on your goals... more torque, lower mileage. Having recently swapped out a weak, worn-out 232+BW auto for a rebuilt 258+904 auto, it was Noticable improvement in power. Not neck-snapping or wow-generating, but definitely noticable. If the 258 is in the same shape as the 232? Probably noticable with a small n :-) Lower mileage by the same amount, depending on the weight of your throttle foot. The old BWs can be rebuilt and are fine transmissions. We are talkin about a stock more or less six and non-racing apps... the even older air-cooled BW in my Classic is on it's second rebuild (that I have done, history before 1988 unknown) and 250,000+ miles. They're fine. > Regardless, I have been collecting various "upgrade" bits for about 5 > years now, I have a clifford intake I was toying on installing when I > find a carb.

Clifford intakes won't do carb heat (at least the ones I saw) and definitely not with headers. If you are in a cold location... headers are hard to fit, eventually rust out, ... to get the CFMs up where those parts will help you, you're out of stock territory. Luggin down the highway at 2000 rpm with acavernous intake and exhaust is a waste of everything. The HEI is a good idea however! And the GM alt are "better" in some ways (mainly availability, cost, ...) but if the current one is charging fine, I'd save the GM project til the Moto starts acting up. _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
