Installing new cam on rebuilt engine (59 A).What is the better choice, alum. or fibre? Have both bolt on gears. Aluminum was in engine originally. Thanks
I have heard bad things about the aftermarket fiber gears now being sold. I read here or on the H.A.M.B. that someone had one fail after only 2000 miles.
Go with alumuinum. I have never noticed any difference in noise on my cars between fiber and aluminum. After having premature failures with the repro fiber gears, I switched to aluminum and never looked back.
Go aluminum gear. Ford used fiber gears in the 70's on the 300 six and I sold a ton of replacement Ford gears for those, plus pan gaskets. They'd strip out and drop the pieces into the pan. Expensive job back then.
