Quote: Since I am to the paranoid part of my project, I’ll throw the question out.
I am going to put new lifters in my motor for peace of mind.
In the past, I used old lifters with new cams (break in to daily driving).
I didn’t want to chance it with this motor…
Has anyone else done this (old lifters, new cam) and had no bad results? I have heard all types of bad stories of swiping lobes because of this, but it’s all hearsay….random stuff on the internet.
So, fact or fiction? What do you say?
P.S. I am changing the lifters with brand new ones regardless.

this is the very reason I upgraded to roller cam in the 318 I have.
no lifter break in needed so no...
I want to swap a cam/lifters/springs in my 440 and have the same paranoid feelings about the break in and it wiping a lobe.
I too have read many horror storys of big $$ engine failures on fire up and break in. most was with a comp cam.
I do know when I was young seeing my uncles swap cams 2-3 times on a good running engine but they always used new cam and lifters.
I personaly have never seen a failure. my first engine i did not even know enuff to do a break in,it ran 10 yrs with no trouble. hammerd it from start up till it droped a valve.
now I have done and read so much I am a paranoid nelly and skeerd to try a cam swap on a flat tappet engine.
all I can say is good luck and 2nd the new lifters over buddys hear say with a new engine.
