I have twin 1984 270's with mallory YL624AV distributors. I want to replace them with a breakerless distributor. Mallory has a YLM624AV can I assume this a replacement for the points distributor I have? gears and all??

The YLM 624 AV is for a LH Standard Rotation engine.
The YLM 624 BV is for a RH Rotation (counter rotation) engine.
Both distributors rotate CW, as the engine oil pump dictates this rotation!
The standard AV "drive" and "driven" gears place an "Up-Lift" on the shaft (this is normal), and is checked via the thrust washer immediately above the driven gear.
If that is the case, then you are correct. Two AV's is all that are needed.I'm really confused with this. Crusader BBC gen IV cams all spin the same direction, so why would the BV ever be used?
opps, i see this is a SB thread. Even so, don't SBC spin the cams all the same way for Crusader?
Is Crusader using twin cam gears (2 gears only) on their RH engines these days?
