I found a couple of readable W-31 articles. Of course the Hemmings is pretty great. The second one is slightly annoying but still cool. Share your links to W-31 Ram Rod stuff (resist linking back to Classic Oldsmobile if you can). https://www.hemmings.com/stories/art...utlass-ram-rod
Performance on the other hand is dead on. Hot Rod wrung the hell out of this engine back in 1968. The Hemmings article matches performance with headers and slicks.
Hemmings stock --- quarter-mile in 14.4 seconds.
Hot Rod stock with headers--------- 14.0 @ 98.90 MPH
Hemmings headers and slicks------ 13.5 @ 103.45 MPH
Hot Rod open headers, slicks------- 13.6 @ 103.21 MPH
Then Hot Rod pushed it further with bigger slicks a tweaked carb and 4.66 rear gear.
-------------------------------------- 13.20 @ 105.75 MPH
