72 360, cam/lifter failure, replacements?

okay, so it's LA that you want to fix.

while my recommendation is still keep the cam reasonable-- i love something like .410/.425 245/255 110LSA for this application, and to contact ken up at oregon to see if he's got a similar grind or can regrind yours; from there my deviation is to find out what happened.

have you ascertained *what* caused your cam to cease doing the bumpstick boogie?

slamming new parts in without due diligence is just a lesson in frustraton and how to lighten you wallet.

Hi Junkyard,

Well, I was fairly certain I had a reason but I very recently informed in an abrupt manner that zinc was not the reason despite the only change was using a different brand of oil. I went and checked other conversations about zinc in oil and see other people reference it for parts failures. I guess I am not allowed to have that reason ;)

I have not torn down the engine. I only got as far as removing the valve covers to observe the rocker arms. I had oil pressure and had not done anything else to this engine in over a year except my regularly scheduled archaic 1880’s oil changes prior to this so I do not have much to go on. I had several plans fall through on rebuilding an engine or doing an engine swap. I kind of need to get it moving so I can address more pressing problems. I don’t want to just throw a cam in and repeat the problem but every avenue I have tried to take has closed.

The cam(s) you mention. Would they be ok for a heavy tow vehicle like a van?

Thanks for taking the time to read and reply with help and advice. It is appreciated.

Mike
