I'm in the middle of assembling my umteenth FE motor. While looking through the old tool box, I ran across a couple of those chromemoly
oil pump shafts and, of course, some stock ones. The chromemoly ones were new. Don't know where I got them or why, but there they were. So, should I use one? For nearly 40 years I've used the stock shafts without a problem. I've built motors with anywhere from 70psi to 120psi of
oil pressure. Never even twisted one much less broke one. But, there they are, free, just sitting there in the tool box. Why not use the bulletproof shaft? Of course, they are kind of heavy. And, if you think about the stuff they're attached to (
oil pump, distributor, distributor gear, roll pin, and cam gear), if one of them starts to go, which would you prefer to have catastrophically fail? I'm thinking the $5 stock shaft.
Can anyone give me a good reason to use an indestructible oil pump shaft?
