    What exactly are 10.5:1 compression cylinder heads??

    The engine has a 10.5 compression ratio. The cylinder head would be rated for combustion chamber size which was no different than other 289 heads.

    "Cast in numbers" is just ambiguous. Don’t all heads have casting numbers??

    “Oversized main bearing caps and connecting rods”, Larger or beefier or thicker may be more appropriate. Oversized sounds as though regular 289s were “sized”.

    Did anyone bid on this one. The date code is July 14 1964 with a consecutive unit number of 100244. Production began at Milpitas on July 13th so this car was a first or second day car.

    Because of frequent failures, the Shelby team, who was supplied these engines specifically for Trans Am racing, asked Ford if they could substitute the more reliable 289's to finish the season. Ford refused their requests. <hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face="Verdana" size=2 id=quote>

    One of the times Shelby spoke at one of our NorCal events he mentioned the issues with the Ford built tunnel port engines. The Ford guys resented Shelby's accomplimants or rather the accolades when Ford received none when the cars won. Shelby said the engines came to them sealed with an attached dyno sheet showing what that particular engine had produced. Shelby's team was supposed to drop in the engine and go. They were not supposed to inspect or modify it in any way.

    Well, one time an engine wouldn't start, so Shelby's team started tearing it down to find the cause. The engine either had no rocker arms or no nuts on the studs.(I can't remember which.)

    Shelby said they called the Ford boys to ask about the dyno numbers etc, leading the guys on until he told them something to the effect of "the damn thing is missing the valvetrain, so we know you didn't dyno it." Shelby said after that they were able to work on the engines and they became much more reliable on race day.
