Is it neccesary to break-in a solid flat tappet cam?

I thought I read in here before that this is not needed on a solid flat tappet cam. Any advice would be good here. If I follow comp cams procedure that would be 14 quarts of oil in 30 minutes I am hoping to get get this thing in and running this weekend, depending on if my intake spacer kit shows up in the mail today.

Solid rollers and Hyd rollers do not have a break-in period. Solids and hydraulics do.

Must be cam week. ALL flat tappet cams require break in. Failing to to follow the break in procedure can destroy the cam and lifters as well as scatter metal through the engine. The oil goes gray and you begin to extrude hone your bearings. I'm not sure what the 14 quart remark pertains to, but it's worth 14 quarts, trust me.

i think that he ment that he would have to break in the cam then change the oil again after the break in. just a guess.

thats what I meant. This a brand new engine with several thoudand dollars invested. I have thought about it and for the price of 7 quarts of oil it is definatly worth the expense to do it right.

You have to break in the cam and change the oil and filter. 10$ for some oil and filter and how much for a trashed cam and the joy of doing it again?

pick up some cheap oil at Canadian Tire or Walmart or anywhere that has oil on sale. Walmart usually has name brand oil on sale so it won't cost too much to load up on it a bit. After the engine's all broken in drain it as well as you can (let it drip for a day or two if you have to) then put the good stuff in with a good filter (prime it again before fireup).

I still have quite a few litres of the 99 cent no name oil I bought for the stk. 351W engine when it had the blowby problem (it took a litre every fill up, that's how much oil it was puffing out). I'll use this stuff to break in the motor then change it again to run the car for a week or so then put the good name brand oil in.

You should know this but make sure everything is good before you turn that key, by that I mean you have a properly working ignition system, starting system, fuel system so that the moment you light her up it should fire up and keep those revs up during the break in period for the cam. I hope to be where you are in a week or so and I am anxious also to get my engine going. Good Luck!!!
