sold to hyd lifters

Matt Selwa said
When I rebuilt my '71 Slant six I decided to convert it over to a hydraulic cam. You will need to do the following:

Replace the camshaft with a hydraulic cam.
Replace the cam bearings since the rear bearing is different in order to pump the oil to the head.
Replace the head with a hydraulic version.
Value cover will also need to be replaced (the hydraulic version is wider)

I was able to change mine over pretty cheaply when it was rebuilt since I picked up a complete '82 Super Six engine with hydraulic cam to use the entire top end on my older block.

I was going for quiet and smooth and I have not been disappointed.

Replace cam with hydraulic cam and lifters.
Do not replace cam bearings. The oil groove is on the cam journal, not the bearing.
Leave the head alone, replace the rocker arms, shaft, and pushrods, with the correct hydraulic parts.
Depending on the year of the head, it might be necessary to change the rear rocker shaft bolt and/or redrill the rear rocker shaft hold down bolt hole.
Use the valve cover that came off the old head.
