Finally hit the track with Pro-Ram intake
The track was in pretty bad shape, they didn't scrape the track and laid VHT on top of last years rubber. The rubber was peeling off like an orange peel, even the big boys were having traction issues and were .5 off their normal times. If you ever come to Esta Dragstrip in Syracuse expect to pay $25 to T-n-T. I really don't care if I paid $10 or $25 the track has to make money some how. But $25 to T-n-T at least they could have prepared the track better .
Anyway, here you go, not happy but a good start:
60 ft ---1.77
1/8 ET ---7.663
1/8 MPH ---92.42
1/4 ET ---11.977
1/4 MPH ---116.46
If I get that 60 ft down to 1.60's it's good for 11.5's or so. My adjustable torque arm was way off. My first run was 12.20 @ 117 MPH with a 2.02 60 ft, but after adjusting the torque arm three times that was when I got a 1.77 60 ft. I stop adjusting the torque arm because I left the angle finder at the house and I didn't want to break anything. But still the track sucked for $25 T-n-T!! All runs were made on E.T. streets @15psi

Yup, along with spohn LCA, panhard bar, and Alston subframe connectors. I just need to adjust the torque arm. I could not use the cross member with the intergrated drive shaft safty loop that came with my spohn torque arm because of my y-pipe for the LT headers didn't allow it, so I had to reconnect the torque arm to the stock location. I need to reset the angle to -2*. It's like I said before, I didn't have my angle finder at the track and I didn't want to hurt the car.

NO SILLY, the stock location on the tranny I have an adjustable torque arm. The first pic was the original torque arm before I installed my LT and the second pic is what it looks like now after I modified it without the spohn tranny cross member.

11SEC91Z,
Yes, the car pulls harder and the best part is the car stays at 100 kpa the entire time at WOT meaning no restrictions. With the mini ram kpa was unstable do to large plenum volume at higher rpm all the air goes to the front four cylinders starving the back four leaving them richer because of the batchfire design fuel injection. But you seem to have your car running nice. I didn't dyno before or after swap so I don't know HP gain or lost. I guess I need to get to the dyno and find that sweet spot and play with the timing a bit. I was running 34* total timing at the track. Won't know until I dyno or hit the track again.
