Very very few people(if any) "make" money drag racing. More like they just use the money to cover some of their expenses.
It's more free parts than any money. Helps regardless I suppose.
Sponsors sponsors sponsors(there's a reason they all wear swag)...and they have deep pockets,,etc. I also think Big Chiefs family had a little bit of money(I heard rumors) but that is speculation more than fact. Ok back to the thread...sorry
heres a few tips that i learned the hard way the last time i put my tko in::
use two long pieces of all-thread in the bell to line up the trans (bottom holes work best, i started with all 4, but it really just needs two)
do NOT use the trans-to-bell bolts to draw it in, the ears can (and will, been there done that) break off
an extra slip yoke on the output helps with lining the input splines up
