I have been asked a question I cannot answer about the cam followers in my 327 straight 8.
My engine is off site and the machine shop is unavailable at this time.
I am converting to adjustable solid lifters and have been asked the dimensions itemized in the below sketch. Note that "F" is the distance above the side casting opening of the block when the valve is completely closed and the cam follower is at its lowest point.
Does anyone have an open block or spare parts that you can measure and let me know?
I understand that some dimensions such as D & E may not apply.
I am very grateful for any information you can supply.
Thanks so much in advance.

OK, inquiring minds want to know why you need this arcane information...as when changing to solid lifters you merely swap out the cam and lifters and you are done. Oh, and drill out the weep hole that shoots oil onto the timing gears to .093 iirc.

As Ross indicated, this information is not needed as it's a simple swap but also just to clarify what he hinted at, the cam must be changed too as the lift is quite different between solid and hydraulic lifters.

Thanks everyone.

Hi Bob. Important point: where are the solid lifters from? Now if you just install new lifters on a worn-in cam, you are going to have trouble. Your cam lobes will be circles in no time.
Cam and lifters must be run in together. If the lifters are used, AND come with the cam they ran on, AND you know which position they originally were in, fine. Swap over. If the cam and lifters are new, put loads of moly grease on the lobes and follow the break in procedure, that too will be fine. Mixing new and used will be a disaster.
