rockers were in the engine when I got the car, no idea what they came out of, lot like the typical stock ones I've seen on the internet for my year car with the mechanical/solid cams. I swapped out the solid lifter cam for a Lunati Voodoo (220/226 @50) lift 475 in, 494 ex, hydraulic, the number I found on the old cam was 292S, the rods that were in there were 7.5" overall length. I tried the 7.33 length, (effective length 7.185) they seemed too long. I have a 5/16 X 6.8 pushrod now. The geometry seems off with both the shorter pushrods, I am going to pull the rockers back off tomorrow to see if I can see any number, will grab a pict. also The engine has a date code of march 1972. I don't have any specifics on the motor, guy I got the car from thought it had a different cam because of an old box that was in the car when he bought it.
