Jim from Nebraska right?
Crabby went 10.17 with a dual nozzle on pump gas and alky.
Your 3.8 and 67 turbo should be about the same.
I believe Grumpy on this site went high 9s on a 67 turbo with ported irons, stock ported upper intake and t-body. ( with pump gas, 60's and alky with Eric Marsalls chip)
Is your car running lean with the current single pump and dual nozzle or do you have a single nozzle?
