I've heard that the later LN 600 & 700 332 engines had higher lift rocker arms is this true? None of my manuals mention this.

 

302 & 332 were Lincoln derived Y block V8's. Introduced in 1956 C/F700/800, the last year they were used was 1963.

L/LN500/950 introduced in 1970, were available with FT engines thru 1978.

 

Yeah I know all that, my question was did they make did a longer ratio rocker arm for the BIG trucks 60-63 with LYB engines?? In 58 they added FE's and the monster Super Duty (Like the MELs comp chamber was in the block - yeah and Chevy 348-409-427Z-ll same design) engines to the truck fleet. A guy wants to sell a set of truck rockers that are supposed to be longer ratio units 60-63 engine.

 

FE's introduced in 1958 Passenger Cars, used thru 1971. Introduced in 1965 F100/350, used thru 1976.

The F100/350 FE rocker arms/shafts are the same as Passenger Cars except for some 1958/60 cars, 1961/68 cars with HiPo engines that have adjustable rocker arms.

 

My original question was regarding LYB engines, but I found the answer all LYB engines use the same rocker arms all years car or truck. Thanks myself for finding the answer!
