Smile What a memory!

Duane, wow you remembered a LOT of our conversation of almost two years ago! Yes, I was undecided about the transmission at that time, but the 2.75 rear end was the idea of the manufacturer. He uses the C6 with a 514 crate engine, a Torker II manifold and the 2.75 rear ratio and likes it. As for me, I have definitely been disappointed in the low end performance. I put in the automatic because of ankle problems I have and figured I couldn't push in a clutch any more and wasn't aware of the hydraulic clutch option. I presume it's a very light action hydraulic assist sort of thing?

Actually the lure of a manual transmission in the driving experience is far greater for me than the automatic. Years earlier I drove nothing but manual transmission sporty little cars (even my 1962 Jag Mark II saloon has a stick shift). Even when I'm slowing for a somewhat spirited turn with my Towncar I sometimes find my left thigh rising and my right arm reaching for the nonexistent stick in order to downshift...haha!
I've looked at a lot of rearend gear options using gear calculators that will show RPM at a given MPH or MPH at a given RPM and no rear ratios work very well with the limitations of the C6 to give BOTH quickness boost AND low tension freeway cruising. From what I can tell, the Tremec TKO with the overdrive would do wonders with a 3.55 rear end ratio but then that's just my conjecture... been wrong before.... It looks like a manual will be in the works for me soon. The Tremec TKO was rated as handling up to 600 ft. lbs of torque and I wonder whether with such a beastly engine I should be waiting on the Magnum? I haven't looked at the Richmond yet, will do that soon as I finish this post. So many variables, so few years in which to sort them all out

Yes, please do hook me up with your friend who is familiar with this problem and might be willing to share some hard earned wisdom! I can't wait to get on the road, I'm still troubleshooting a steering rack leak and the rear suspension problems inherent in the kit. I'll PM you with my personal information

Dirk
