According to a May 1998 Classic Trucks article titled "The Six Pack gets a TH-700R4- part 11", you need a Chevy patterned TH-7004 & a starter from a V8 that matches the ring gear tooth count. So, in almost verbatim...

The flexplate used was a TCI #399273, 168 tooth for a small block- but it is not a direct bolt-on. In a previous article, 1 of the 2 dowel pins used to locate the og flywheel was removed when they did the crank balancing (they wanted it perfect), you'll have to do the same to get the flexplate to fit.

Torque converter to flexplate bolts are metric; GM #1261968 (10mm-1.5 x 15mm).

Sixes use 1/2"-20 bolts where V8s use 7/16"-20 bolts, so, the holes on the flexplate must carefully be resized with a 1/2" drill bit. The holes must be as tight as a virgin or you could end up with a loose flexplate!

Next you will need a set of flexplate bolts that will fit the crank flange & extend fully through out the flange, but not so far that you hit the rear of the block. The part they used was ARP #200-2904 (made for Pontiac). Because there are some differences in bolts & converter designs, make sure that the flexplate bolts are not too tall (where they hit the front of the torque converter). Pre-fit everything by installing the bolts in the flexplate with the converter located & insure that there is a gap between the bolt heads & the converter.

The starter is a standard SB Chevy used in many small block applications. Take the time to properly shim the starter. Also make sure you use the support brace at the front of the starter to the block. This brace is critical to correct support and often makes the difference between a burned out starter & a damaged ring gear and a long trouble free life.

A new driveshaft was built by Denny's Driveshaft Service in Kenmore, NY.

For mechanical controls, a stainless braided type of TV cable #KD2700-HT by Lokar.
Flexible bellhousing-mounted dipstick tube #TD3700-TM.
Shift linkage #ACA-1800
To accomodate the trans lock-up solenoid, TCI #376600 kit (installs on the valve body in the og locations & links to the brake light witch). However, the author states that this is important in 2 ways. (1) you must pwr the solenoid circuit and trigger the solenoid w/ a pressure switch to engage lock-up, (2) you need a means to release the solenoid and lock up when you apply the brakes. /the TCI kit is a sinple way to manage this.

Hope this helps!
