Small point, I did not notice being mentioned. Main reason for the gear issue is that roller cams are different steel and different manufacuting ways. I regular stock dist. gear up against a roller cam is like a stone and a diamond saw. It grinds it away in a very short time a wastes your engine with small metal grindings that go right through a filter. Like in the Ford Motorsports Cat. in the gear descriptions-via color- that is the only way to tell and you will see the light. Some cam co. are pressing on differnt gears to the cam which allow you to use the regual steel ones. I lost a brand new 347 stroker with the gear I bought and was recommended from com cams- They did say they were sorry and gave me a new cam and the right gear- I ate the motor.

Aviaid makes a good product ....but..... some things you may have to do.....

If the pump weeps between sections...... you may have to disassemble and use some clear RTV ..... light small coating between the sections to prevent it from leaking...... fairly common with Aviaid.....

The Aviaid pump will not pull a vaccum in the crankcase......yes it will suck the oil out of the oil pan with a 3 section pump..... but just doesn't have the power to pull a vaccum in the crankcase.....

Venting is most important...... you need a 1.5" vent on the oil tank ......and a 3" vent on the motor..... one dash 12 line in the crank case and one dash 12 line in the top of the motor ..... intake or valve cover going to a catch can that has a 3" opening...... only then will the motor breathe and not push any oil out of the various places .....like valve covers.... intake manifolds..... or rear main seals.....

These motor are quite large and those pistons are large and move a lot of air ...hence ....the need for a lot of breathing....
