Great advice! Thanks. I just called Napa and they can get the pushrods for my in less than a week at $8.70 a piece plus $10 in shipping. SWEET! But I confirmed the size at 11 & 1/4 inch and was informed they are 11.474 inches. Here is my dilemma: I "thought" I had an original 235 in my 1953 5 window 3600. After checking the casting numbers my 235 block turns out to be cast in 1959 ( CON3 L 19 ) While the casting number on the head is 1956 ( F 14 G) and the guy at napa had no listing for an 11 & 1/4 inch push rod.

Hate to wait a week and find I have the wrong pushrods. Will the difference in length be important?

Thanks ( again) in advance.
