What mods for my 904 when using the BPE 408?

Its a Magnum block. It can easily bolt in place of any LA engine.

A. It uses a Magnum weighted damper
B. It uses an LA 360 flexplate / flywheel.

Its an aftermarket rotating assembly, it requires less weight to balance than a stock 360, so the nose gets the slightly smaller, Magnum weight when we spin it up and balance it.

Any confusion is kind of a mute point as the aluminum headed engines come with the proper damper already on them, and we sell the damper outright also.
