And I had a blast!!! The car does need to be tuned more, but that is why I went, to try and dial it in. However, as much as fun as it was, I believe there is still more in the car due to the mph I was getting (I cant seem to find a chart that converts mph to ideal e/t, but i did do the 1320/mph calculation to get close). Im thinking I am having some suspension issues and possibly need to alter the jetting in the carburetor. I was getting about 13-13.2 AFR according to my wideband in 4th gear at about 4900-5300rpms (kinda hard to watch the gauge during the rest of the run, and i cant datalog it right now since the cord i have doesnt work). Anyways here is a rundown of the night...my foot did not come off the throttle on any of the shifts, and I had a blast! Stick cars rule!

Pass#1- Caltracs with 0 preload (bars just touching), rancho rear shocks on 7, 9psi in my e/t streets (no tubes, and yes, its a crappy gauge so the numbers are abnormally low- on my buddies decent analog gauge that equates to 14 psi in the tires), half tank of gas, launching at 4000rpm off the two step and shifting at about 6000rpm
R/T .000
60' 1.88
1/4 12.936
MPH 107.15

Pass #2- Same as Pass #1
R/T .285
60' 1.888
1/4- 12.932
MPH- 106.72

Pass #3- Same as first two passes, this time leaving off the two step at 4500rpm
R/T .278
60' 1.807
1/4 12.734
MPH- 107.59

Pass #4 Same as all other passes, 5000rpm launch
R/T .505
60' 1.753
1/4 12.67
MPH 107.94

Pass #5 (best pass of the night)- Same as pass #4, but rear shocks tightened two clicks to 9 (max)
R/T .390
60' 1.742
1/4 12.615
MPH 108.43

Pass #6- Same as pass #5 but tried lowering 8psi instead of 9psi in the tires (according to my crappy gauge). Blew the tires right off and almost went straight into the wall. I got out of it in a hurry and ended up with a 14.49 e/t and 89mph...just happy it wasnt a disaster

Pass #7- Same as pass #5
R/T .145
60' 1.776
1/4 12.71
MPH 107.69

What do you guys think? I feel the car has more E/T in it, especially after that surprising mph on pass #5. I am getting some air under the front tires on launch, but I kept feeling a bog from start to end of night (why I kept raising my launch rpms). It got better the higher i went, but it was still there ever so slightly. I also think I need to possibly add some preload to the bars. Also, how normal is it to have fire coming out the exhaust sitting on the two step and powershifting?

Im going back out to the track next week, so any suggestions for tuning are appreciated! Overall I am VERY happy with how the car is performing and I'd like to give a big thanks to everybody on here who has given me a hand with all the questions ive asked, and most of all Brian at IMM engines (member OU812) for setting me up with a killer head and cam combo that is what really make this engine what it is. I built this engine for 3k, with a bone stock bottom end, and I couldnt be happier, especially considering I think it still has more in it. I drive it everywhere and constantly get asked if its a big block lol

Thanks everybody
