Mr.Glad is leading us astray by suggesting that the engine in the Mustang funny car "looks like a 385-series big-block making it likely a 429". How about an FE series and more likely a 427 SOHC?
That is definitely a 427 SOHC, king of FE engines. I'm surprised Douglas didn't recognize that one, since he has seen one of those engines installed in my '64 Galaxie at the CC Summer Nats a couple of times. Jack Chrisman was using those engines all the way back to '65, in his blown fuel funny cars. But in 1969 it was Mickey Thompson, also running a cammer powered '69 Mustang, who won the first NHRA Funny Car title.
Jeez guys, "Remain silent and be thought a fool, open your mouth and remove all doubt." If you don't know what motor it is and can't be bothered to read the valve covers don't guess! This is worse than the November Rear view describing a pair of Bowers magnesium blowers as 4-71's! Makes me wonder about all the other info in the mag...lol...seriously, it appears you need a old fart on the staff to keep your history in lineTom
