I know this is a very generic question as it would depend on your set up, but I'm going from a 3,200 to a 4,400. The best I was doing dead hooking at the track was a 1.87 average 1.89. If you look at my dyno, It needs more verter period. I shift at 7,400.

If you had to guess, what do you think the new 60's would be?

Any of you have first hand with converter swaps and what they did for your ET?
