Definitely impressive for a H/C car and with the weight!

What does the car make for power? What was the DA on the run?

About 440rwhp but that was with the old converter combo. It's gained a couple of mph since.

DA?

I bought some 245/40/18 et streets to try next weekend, theoretically it may run 127mph with these

Your trap is VERY low. 114 is low even for a cam only car IMO. You should be trapping at least 120 with a donkey dick cam like you have with heads...your heads ported? You should look into getting a FAST intake too. I happen to have one for sale lol.

EDIT: Not trying to thread steal, congrats on the time OP. For some reason it seems like my car doesn't pick up enough on the back half of the track, your times being proof of that. Trapped 98 in the 1/8th but only 122 in the 1/4. Not sure if it is the 4.10 gears and me running out of RPMs or if it was just too hot that day or what.

Last time I went out with the 245 radials I was struggling with traction issues with poor track prep, spinning off the line but still with mid 1.5 60's
Trans tune still isn't optimal with it shifting at 6200ish rpm when we have the rev limiter at 7800. This engine loves to rev hard.

E85 is great, no other way to describe it

Not sure on the DA, time slips don't have it.
