Precision Industries 9 inch spragless race converter.
Billet cover with dual mounting for 168 and 153 teeth.
FRESHENED BY FTI with new bearings and balanced.
Approx stall ranges: BB 5500-6000 565-598 range ci
Would take a small hit of nitrous depending on engine size, obviously a SB app would allow more nitrous than a BB app..
Not for a 632 with 2 kits, or even 1.
Has been some years since I used it, but as I remember it went 5900 behind my 580"BBC, and used for bracket racing. It is not a unit for a lot of nitrous or big power and nitrous.
I spent 300 bucks freshening it so I could sell it as a "KNOWN GOOD UNIT" so 500 is a fair price so don't bother to offer any less than 500.
