What convertor ?

[Dwayne]

I'm using a precision n/l conv. with the "0" pump. I've been told and read that when you start making some hp that the precision starts to fall flat. I've also read that to spool a 70 gt that a guy would need at least a 4000 stall. I had alot of trouble spooling the car last fall until Steve Y took some timing out down low and then put it back in at about 3600 rpm. This helped quite a bit..............I'm just fishing for suggestions....thanks; Dwayne
