Ive just swapped a Built Th350 in place of my 700R4 in my 1986 Camaro IROC-Z.

There are a couple of things I need to know.

1. with a 1986 Manual Speedo 240Km, a 3.23 rear ratio, and a stock IROC-Z rim and tire combo (25.45)?. What speedo gears would be needed in the Transmission?.

2. There are several Detent cables for Th350's. Does anyone know what cable from what type of car would be closest to the 700R4 cable?. What I mean by that is, one that will work with a demon carb and a holley linkage bracket. IF you have a GM PN that would be great.

Thanks in advance.

A detent cable for an '84 chevy pick up with a th350c has an end just like a 700R4, not sure of any other specs on it.

 

Thanks Jay.
