This topic gets discussed once a year or so. Same results every year. Someone claims so and so has a factory C and we go thru the motions and find out the C is a W and that no C was ever installed in a 69. Trouble is every year there are new guys who haven't learnt yet and sometimes when we learn things its "difficult" to accept the facts.
Ironically this very arguement led to one of my best longtime friendships.
I was having a leak in grade 12 washroom and some of the other guys were discussing what was faster C or W. I listened and left. Months later I was working a new job and a guy who seemed smart enough engaged me in conversation about this C vs W thing. I stated the C was the ticket as was the case in 1979 still. Cs were beating Ws and bowties and almost everything else.
Anyway buddy says "No way man its the W. The W is the ticket engine."
Well, OK Have it your way and I ended the conversation basically writing the guy off as he clearly did not know nothin' bout Blue Ovals!
A few days later he approached me again and this time apologized. Told me he was mistaken and after talking with his Cougar buddy Tim realized I was indeed correct and not so full of it after all. Well he and I became freinds at that point, a friendship that has lasted over 25 years now.
So U see my young friend that this arguement has gone on longer than U have been with us on this planet.
People make mistakes. Few ever fess up to it and yes I am that petty I would write someone off over it too, lol.
