i took mt 1959 352 and had it bored .050 and using 390 crank n rods. bought crane 901 cam had front of block tapped for cam retention plate. now the question the oroginal lifters are 2.00 in tall the lifters that came with cam are 1.840 do i need different lifters to make this cam work or do i need longer pushrods thanks for any help keith

just a update to my question. the pushrod does sit at the same height installed the difference is the outer shell of the old lifter is taller. is this ok?

Sounds too me like you need .140" longer pushrods to bring the geomitry all back to zero.... JMO..

the push rod still sits at the same installed height at the rocker arms i was wondering about the height of the shell that sits in the lifter bore?

Is the block an original solid lifter engine?? If the lifters you removed were solids, it cannot use a hydraulic lifter cam. The early blocks can be solid lifter only. Check the lifters you removed, if you still have them. Oh, are the rockers adjustable??

I think 58 blocks were solids, in 59 they went to hydraulics but still had adjustables if I remember right

the old lifters were hydraulic just shorter in body height

the rocker arm geometry appears to be correct

does your 352 have adjustable or non adjustables rockers?

If the pushrod seat in the lifters is the same height from the base, then it is just a different style I would think. As long as the pushrod geometry is correct there should be no problems, just make sure the lifter is not uncovering something in the bores that was covered by the old, taller lifters.

hiball, you are correct in the years you gave. There were more solid only blocks after that, but not many!!

i think they will work as the oil port in the new lifter is in same place as old when both lifters are sitting on their base. they just looked a lil strange when i dropped them into the lifter bores thanks guys
