[Spits] Cam Bearings in 1500

[Joe Curry]

The best way to install cam bearings in a 1500 block is to use a cam for an
engine that was originally equipped with cam bearings.  That way you don't
have to bore those journals.  The Mk3 for example had cam bearings which use
the same size block borings as the 1500 but have the cam journals sized
smaller so the bearing will fit between the block and the cam.

Hi,

I am rebuilding the bottom end of my engine - bad rod bearing.

My cam looks like it is in good shape and is only a couple years old. I will
ask shop to verify.  

I am thinking about having cam bearings installed - I have read arguments on
both sides.

As I understand it, the normal process is to install cam bearings then use
an earlier small journal cam.  Is there a bearing set that will allow me to
use the large journal cam I have?   I realize the block would have to be
bored out to accept larger bearings.

Thanks,
Roger Elliott
