R3W7 Assembly

I have a BFN gear drive in the shop. I’ll look at it tomorrow and compare it to my I forget how old GD.

All I have ever done is drill a hole on the mounting plate where it covers the passenger side oil gallery, tapped it for 10-32 and screw a holley air bleed in there with about a .040 hole in it.

It doesn’t directly squirt oil on the gear train, but every time the holes in the cam gear line up the oil certainly blows straight through that hole and then it hits the back side of the timing cover. I have never seen any wear from lack of lubrication. In fact, my GD came off my last drag engine. So I bought this one in 1986 or 87. And it still has the OE thrust bearing and idler bearing.
