I didn't read the previous 5 pages, but my mate did 10.6 with a 428cui in Germany, fuel injected and not too radical engine. Ever since he battles to do the same time, even though he has plenty of drag time. Under 11 often, but 10.5 not...
He uses slicks and is no stranger to high speed, even though we are looking at only 130mph top speed, or so.
I want to hear the result!

This is the 10.9, I can't find the 10.6 video (maybe on his website?)
