Seems wide support for the Crower 60240, though have not been able to find any videos of its idle. Realizing the choice of exhaust will affect the tone, would like to hear the idle sound to see just how smooth. Anybody running that 60240 cam in a 400 and have a vid to share? Kindly advise.
Thanks so much!

If you're keeping it very close to stock using the original log exhaust manifolds and Y-pipe (or true duals), I wouldn't go with any new HFT cam larger than the 2800 myself. You'll only have very low 8's compression like Cliff said, even after a resurfacing. Here are the dyno sheets for the '79 W72 with the original Y-pipe and then with 2.5" mandrel bent head pipes...FWIW. Dan also dyno'd it with RA manifolds to see what improvements they made.
