A 0.64 on a T25 is equivalent to about 0.54 on a T3 or the KKK you have.
An intercooled 4 litre engine at 4000rpm could overspeed the 0.49 A/R T25, possibly killing it, that's why I'm relunctant to suggest that one.
I'm running the T25 on my 3.9L outside it's limits already, but I'm much happier to experiment on my own truck than leaving someone else stranded.
