0 pump to 6 pump

[forcefed3.8's]

I have a 0 pump Vigilante in my car now, I have a 6 pump on the shelf. They are both single disc, so no WOT lock up. How much top end will I lose going to the 6 pump?

About 1-2 mph i would estimate. Since i had both conveters before.

Norbs is right.

I thought a little on the reserved side. I figured with no other changes than the converter I'd say 2-4 mph. The O pump is a positive pitch pump {with eng rotation} and the 6 pump is negative pitch pump {away from engine rotation}. Positive to neutral fins make mph.
