I got the new lifters from TL today. I also ordered a new set of pushrods. The new lifters (solids) are the milk can type. The push rods are the longer ones. I had in the motor the shorter push rods and the straight solid lifters. This is a 1957 motor. Is the milk can/longer rods right? Is there any advantage to the milk can design for this year motor? I don't know if the straight lifters were changed into the motor or not, it had been rebuilt some other time before I got it.
