My new 455 Build
Recently (should read: "Finally!") got the 455 up and running in my '65 GTO post car. Only has about 250 miles on it right now - due to change the oil tomorrow before putting any more miles on it. So far I'm extremely pleased with the Rhoads lifters, I'm running cast alum. valve covers and the noise is not excessive to me at all (like someone else said: sounds like a sewing machine). Waiting for Dave's small-body to arrive and my completion of the '66 TriPower before I can say "it's done" (powertrain).
