Ford rated the 427MR at 485HP @ 6000RPM By Dave Shoe - 04/26/2001 11:01:42 AM; IP 216.243.158.182 Cool info! The "rear wheel" horsepower numbers of your 10.0:1 version of the MR appear to correlate well with Ford's published "crankshaft" numbers for the MR motor. The various twin carb 427s were rated at: 427LR 425HP @ 6000RPM 427MR 485HP @ 6000RPM 427HR 540HP @ 6300RPM 427SOHC 657HP @ 8300RPM Note: The SOHC rating I list is for the "Second Series" Cammer, the first series Cammer "prototype" (as planted in that famous '64 Galaxie) only came in a single carb version. Note that a different Cammer chart I've seen stops at 8500RPM and shows the twin carb Cammer passing through the power peak. Don't consider my writings as "fact" until you see the info from the original source. Info shown below is available to anyone for $13.51 (includes shipping - $11.51 to members) from www.sae.org in the 21 page "427 SOHC papers written by the designers of the Cammer. SAE paper number is 650497. Delivery about one week. The "8500RPM charts" are not part of this document, and I believe were published by different authors. Charts below represent the second series Cammer in both single and dual carb configs, as well as the dual carb 427HR. Shoe.
