Ok, well I was just watching My Classic Car and they had a '65 Daytona coupe on it. They said it was estimated at 390 hp from the 289. In my search for knowledge, anyone know what Shelby did to these 289s? Man, I about passed out when they fired up that 289, that is pure music.------------------

4 Weber carbs, an Isky roller cam, ported and polished heads with 1.94 and 1.50 valves, 13.5 to 1 compression, big tube headers about covers it. Some rare cheater 327 inch 289's floated around also.  ------------------

Alex don't those heads have 1.875 and 1.625" valves? And i think the exhaust ports were ported round like the Crane heads.

Tom, the Daytona package engines had 1.94 and 1.50 valves. It was legal under international FIA rules. The SCCA Cobra's had the smaller FoMoCo GT-40 valves. Also, you are correct, the exhaust ports were round just like the Crane heads on the FIA cars. Again, the SCCA 289's were limited to match porting.  ------------------

Four Weber 48 IDA's with 40mm venturis, and the cam was a solid lifter referred to as the "Le Mans" cam. Stock compression (pre '65 hipo) was 11 to 1, but the Daytona coupes probably ran a higher compression ratio.I have an original Shelby brochure listing these complete engines for sale at about $600.

LeMans cam was a C7FE-6250-A which predates the Daytona Coupes a bit. Shelby had Isky or Engle supply most of their cam grinds. The Daytona Coupes, as all FIA competition cars used roller camshafts. Shelby liked to fib a bit in his sales literature as to what the over the counter parts were compared to the REAL competition parts. He didn't want to get beat by his customers. ------------------
