fitting cam bearings

[Gadgetman]

Has anyone had a block line bored to take a set of cam shaft bearings? just considering getting this done whilst I get my cam liter bores taken  out to 0.800"

Also has anyone used the Tuftrided lifters with an oil hole in them??

On a 6 presumably? No machining needed on a 4.

For a 6, cam bearings are not necessary unless the block is worn or a very high lift cam/high rpm/strong valve springs are planned.

Otherwise it's just a fairly expensive "nice to have".

If determined to have it done, from bitter experience you need to be sure that your machine shop has the machinery to bore the whole length of the camway in one pass (it's too long for many) and the expertise to use it properly. Anyone who thinks they can do a satisfactory job by working from both ends should be avoided. Cost me a fully machined block and a lot of pratting about to learn that.
