I'm not looking to run it just curious? It's only .5 more than the 561 and 741. 110 might be a little overkill but it would sure smell nice. I run that in all my muscle cars. Someone should make that into cologne. I would imagine you get plenty of wiffs of it also.
I'll call you tomorrow regarding the trans.

I hope something happens. I heard a rumor that comp was looking at buying their assets. It would be a shame to see them go all together as they have some great grinds.

How about this one? Might be a little on the large side for my 496's? I might be wrong though as I have hever run one. The lift don't bother me just the duration. Let me know Pro1 if you have any experience with it. I'll bet that thing would bark at an idle.
