well I've had some inquiries as to how the car ran last week. Hauled down to Phoenix to partake in a chassis cert session and entered the test and tune. At this point I'll say the engine ran great.... however... Between going full retard with a new combo, and a shifter that decided it would make the 1-2 shift on the hit, we didn't get one real good pass out of the five. I'll condense the five passes into one time slip between flubbed shifts and tire spin:
1.28 60 best out of the 5 and best for the car. this shows hope. minimal wheel stand.
6.100 to the 1/8 on that hit... new best. 113.45 @ the 1/8.... another new best.
9.644 1/4 @ 141.12.
Guess that will be my baseline for things to come.
We dynoed the engine with a Quick Fuel 1050.... spacer and my dominator wouldn't clear the hood, so I grabbed the 4150 BG carb off the 360. Now we knew absolutely nothing about this carb other than a friend bought it at a swap meet ions ago (IIRC it was presented as a 930cfm) and we'd used time to time on different engines. It always worked well, as it did on this engine. But I finally did a little "learning" and came up with BG4779-3 with 1.68 throttle plates is basically a really good 750 cfm carb. Perfect for a small block....but probably not this one.
The shifter.... the love/hate of the T/A Cheetah SCS seems to run very deep on both sides. I've been told the "SCS" means Sometimes Continues Shifting.... I learned the difference between a "gate" shifter, and a "ratchet" shifter. I was ready to give PPP my hard earns, but after calling them and talking options my head was ready to explode so I sat back and weighed my options. I called TA and talked to Paul.... of course I'm the only one in the universe that has had this issue, but in talking with him I came to the realization that I might be able to work this out. I dropped my Griner valve body out friday night and to work we went. I removed the "rooster comb" and shimmed the detent spring. I also took a die grinder to the 1st gear detent and after about 3 hits of increasing it's depth and steepening the ramp I could hardly shift it on the bench by hand. Installed it in the car and BANG! I can now feel 1st and it won't drift back into 2nd, but yet shifts firm. Might have saved myself a little coin with a die grinder/beer session. I probably should have done the same to the 2nd detent, but the gate on the shifter seems to work fine for 2-3.
Only other "big" issue of note was that when I had to really lean on the brakes toward the end of the shutdown on the 1/4 passes was that the oil psi dropped. We added a quart for the last hit and it didn't seem to make alot of difference. That might take some thinking.... Easy button might be a clean N valve body
I've got alot to learn, changes to be made, but realistically I think we'll get 147mph out of it. Maybe not in Vegas, but I think it's there.

AFTER I learned to stiffen my arm up a bunch before hitting the throttle so my hand and arm wouldn't move backwards at the hit making the shifter shift 
Your not the first and I'm sure you will not be the last one to have that happen on a shifter like those in a car that moves really hard. I've even hurt my hand on my old 1963 Bracket Beleveder(1.49 60 ft.) when my hand flew off the shifter and hit the roof roll bar behind the seat 
I had to retrain myself to push myself back into the seat before letting go of the button on the new car to make the stupid car quit hurtng my back during the run, especially last year when coming off the throttle stop
