mystery motor

[John_Calabrese at ENGELHARD.COM]

"You are exactly correct, this is the engine pontiac hired Jack Braham (sp)
     to build for Pontiac for either 5.o liter Trans Am racing or the Braham
SPFP
     firebirds, the rumor is that only 3 were built. The core plugs and trans
     flange are like a Pontiac Block. A Photo appears in Mike Lamm's Firebird
     book with a little info. This is an extremely rare engine and Pontiac corp.
     would probably be interested for the company museum."



I heard that It could be Jack brahams motor.  How much more info do you have on
this motor?  What about books with pictures of this motor?  Where is the pontiac
museum located?  phone #?  Any performance numbers on the motor?  HP?  RPM?
Thank you very much..
