Can I use this POSI unit?
Have a chance to pick up a used GM POSI unit for a good price. Obviously would rebuild it, but its a 8.5" 30-spline and I know we should avoid the GOV-LOK models... so is this one of them? Don't mind extra cost of 30-spline axles. Going in a '72 Nova 8.5" 10-bolt, and if its useable, any limits on gears? I'm wanting 3.42 ring and pinion for a 4-speed BBC.
'69 LeMans Blue Coupe, White Interior, Massaged .030" over 454, Super T10 4-Speed,
Holley 4150, Pertronix Ignition, CompCams Xtreme Energy XS274S, 781 Oval Port Heads
