Hi everybody,
I know that very few of us cares a whit about this subject, but I think that
we should be sure to set the records straight for posterity.
Recently, I was going thru some of my personal library documents and I came
across a letter from Bob Kirkman to me, dated Dec 1987. You will remember
Bob as the GM Corvair engineer who compiled all the cyl head drawing data into
a single spread sheet that was published both in the Communique and also in
the Corsa Technical Guide supplement.
What Bob said in his letter was that he had reviewed all the Corvair cam
drawings and they all (except one that he said was in error) referenced the
rocker ratio as 1.57 and not 1.50.
That is to say that all Corvair rockers were the same ratio at 1.57. And
that 1.50 was picked up and used incorrectly as there was never a 1.50 Corvair
rocker ratio.
Regards,
Bob Helt
