Is it a roller? If not make sure you break in with correct oil I like rotella

No, A Lunati 703 hydraulic. I'm thinking straight 30 weight for break in?

Today more than ever camshafts are cooked in the first few minutes due to many reason but number one is insufficient oil and not having the engine in tune ready to fire, I always suggest high levels of zinc, be sure timing is preset and if carbureted fill the bowl and be ready to fire, dump oil after break in then put a good oil in and roll
You are familiar with break in procedure? Happy to assist here

Never changed a cam b4. Doing some googling, read lunati's sheet that came with the cam. Asking the odd question here.
From what I understand, prime the oil system with the hex shaft and a drill.
Fire up the engine, run at 2500rpm for 20 minutes or so, the 3000 for a minute, then 3500 for a minute, then back to 2500, then done?
Getting it to fire initially/setting timing might be tricky.
Any and all advise welcome.

Yes I usually like 2000 rpms then decelerate then back to 2000 occasion 2500 find tdc get close make sure to fill the fuel bowl, cranking then engine on new cam is deadly priming is good but I usually pour my oil over cam and lifters before installing intake

The Lunati instructions are fine.  they have been in the business a long time :)

A couple of suggestions.  Fill the carb bowls thru the vent tubes to the normal level so you don't waste cranking time to get the carb working normally.  Be sure that you installed the distributor on top dead center and not 180 degrees out so the engine fires and runs properly immediately :)

It should be good! :2thumbs:

 Don't forget to prime the oil pump counter clock wise with valve covers off so you can visually see the oil coming up,you will have to turn the crank to get both sides oiled then put it back to tdc on compression stroke.It is easier to have the plugs out to rotate it but not necessary and you can feel the air coming out when you get it to tdc on the compression stroke cylinder #1.Have a friend prime it and watch your oil pressure to verify its going up and have someone with a lil pop bottle with gas to keep it going it it decides to try to stall.Also have your timing light ready,crank it up to 2500rpm.Do this outside incase you get a backfire or worse.
