[bl-is-future]

well in my experiance with MY savage conversion is as follows.
maxamps batteries = junk (puff under any load, look forward to a new batter every run)
three speed or two speed not locked = tranny explosions
plastic bulks under any bl = diff exploosions
cheap motors = junk

now for the good
good battery = non puffed batteries which = less cost in the end
locked tranny = no problems at all
flm bulks = no diff problems (except bearings an out drive cups now and then)
good motor = happy camper (just go with the castle neu 2200 and you will be fine)

so figure in at least the flm bulks in your pricing too. The stock plastic flex too much under all the power. I run 18/47 gearing locked in second on a 3 speed. it is plenty stupid fast.
