Part 5 – Offset Distributor. Build Notes

I decided to keep the MSD distributor with the old Daytona cast iron engine. That mild engine used a custom advance curve (springs, etc). So, I needed one for the new B1 engine and found a lightly used offset distributor made for Predator heads. It moves the distributor cap away from the head and uses a large diameter cap (Ford style).

1) It has adjustable rotor phasing.
2) The base (with o-ring) is adjustable for shaft length as it clamps to the bearing housing part of the distributor

When I bought it, the tip of the shaft was 4.196” from the base (where it touches the block). I loosened the two allen head bolts that clamp the base to the distributor and installed it in my block with the bronze gear oil pump drive shaft that I am using (Milodon 21525). I pressed the assembly to bottom in the gear tang slot and tightened the allen bolts. I removed it and the zero endplay length was 4.176”. I made a small adjustment to give me 0.007” endplay; resulting in a length of 4.169”.
