HotRod Mag 408 build w/TrickFlow heads NEW

Its a valid point on the cam bearings. I don't know the magic cutoff point but the use of needle bearings is in fact driven by high spring loads.

If the headers aren't 1-3/4, what are they?

Hooker 5303 1.875 headers.

I ran 340 on the seat and almost 900 over the nose depending on lift and never killed a cam bearing IF the idle oil pressure is 40 minimum.
