8 3/4 chunk math - sticker shock

personally i thing the 741,742, and 489 crap is just that. crap. i had a 741 behind a 440 for years. i believe there is a 741 in my dart too. launched it hard enough to get a couple inches of air under the tire numerous times and have never hurt it. but if you insist on a 489 then you have two choices. pay a cheaper amount for a used set that may or may noy not be set up properly or just spend the money for one that is guaranteed to be right. and i think i would go trutrac over a clutch pac if starting from scratch... nothing about this hobby is cheap. just something we all have to come to terms with.
