Can anybody help me with a few questions for my book?
In 1967, Milt Schornack with Dave & Sid Warren worked an OHC 6 with Thorley-designed headers, and a Man-A-Fre tri-power intake. They also Bobcatted the car -- with some amazing results.
I need to know...
a) what was the first production year for the Tempest OHC 6?
b) Was the 250cid the only available displacement?
c) Has anyone driven one? What kinda performance did you experience?
Thanks in advance!
