Killed another cam, need to go roller, need recommendations

Lxiflyby said

2 different engines; the last setup was caught in the beginnings of a couple lifters starting to gall up, so the pan was cleaned out and a couple of bearings were checked and it looked okay. Replaced the parts and made another go on the outer valve springs only with driven break in oil, plus the engine started almost immediately. I ran 20w50 valvoline VR1 after break in. I don’t think I have more than 100 miles on it… I wasn’t planning on tubing the block

If it’s getting solid lifters I always suggest at least tubing the block.

You don’t have to do it but like PBR said the leaks at the lifters are horrible.

Also, 350 open isn’t that high. That shouldn’t kill a lobe.

To that end you need to accurately measure the lifter bored for size and geometry.

If either is off it needs to get bushed.

There is a company that sells a do it at home kit for bushing the bores. Understand that that system does NOT correct lifter bank angles. It just gets the bores back to size and geometry.

It lines up on the existing bore. If you have a couple of lifter bores that are wonky you’ll want to correct that even with solid roller lifters.
