Fastest 904

I have run 8.60's with a 904 with 2.45 1st gear in my 91 Dodge Datona with a 383 small block with W7 heads. Car 60 foots 1.20. Trans has a billet input shaft with brake from A-1. Going to A-1 Proflite as I need the lower first gear of 2.13.
I did put a glide in the car as everyone told me it would work better, but at the shift it causes too much RPM drop. My W8 motor likes RPM.
