I run an 8" Ultimate. Stalls at 5200 behind my 468.
3.91 gears, 40 miles at a time no problems so far.
I called Lenny and talked to him, told him it was going to see many street miles.
I basically said "build me what you think will work best".
It's been great.
Since I run OD I had Lenny tighten my 5000 stall
TA conv up a couple hundred rpm so it would be
a bit easier on the conv when in OD and keep the
slippage down.. he did a nice job on it... at that
time I had him cut off the mounting lugs and weld
on new ones.. my old ones were starting to strip out
