Interesting. My '68 400(0.30 over, ported RA II heads, 12.0 compression, with long branch manifolds through 2 1/2" exhaust w/goerlich xlerators) with the melling copy of the 041 cam is quite a bit quieter on start up. But then I don't drive it enough so it may be wishful thinking on my part(I prefer a quieter idle.)
