Tell if this is right,
Let the car run at 2000-2500 rpm for about 20min.Then change the oil and your ready to go.
I'm not to this stage yet,but just making sure I understand.

Can I just use water only while I break in the cam.I'm replacing the water pump too.And if it leaks I dont want to dump the coolant.I dont mind changing the water to coolant after cam break in.

Yes, that's how you do it.

Water is fine. In fact, I like to keep the radiator cap off and a hose handy so I don't run low on water. You usually need to add water when the thermostat opens usually about 5 minutes after it starts up.

Isn't the cam you're getting a used cam? If it is, you shouldn't have to break it in again.

He's using new lifters, I believe.

Ron,

I'd use either some antifreeze or rust inhibitor during the break in period.....it doesn't take long for the inside of the block to rust with straight water...but, you may have enough anitfreeze left in the block even after removing the timing cover....

just my 2 cents....

No fast Fords at this time but one fine cruising 96 F350 CC DRW Power Strokin diesel.
And one rusty 64 Fairlane nick-named the Rust Bucket....And sometimes called the Money Pit...

I didn't realize that mattered. Of course I've never installed a used cam either. Why would he need to break in the lifters if the cam is already broken in? I thought the breakin process was primarily for the cam lobes.

The new lifters still have to burnish into the cam lobes. There is companion wear on both the lifter foot and the cam lobe when it fires up just like on a new cam.

Am I getting a bad report? A man at a noted business says that I could change the B303 roller cam in my 5.0 HO to a E303 and use the same roller lifters as it is not critical. Was surprised to hear this. Any thoughts as I am considering the change.

He's right. Rollers are very forgiving. You don't even need to break rollers in, just start it and go.

A new cam??? COOL! I thought you were picking up a used 'stick. What grind did you decide on?

The summit racing cam and lifter kit.
It's the same cam as the Ebrock performer cam.
Duration @ .050 204-214
lift .448-472
And at $83 it's a great price.

You got that right! Lifters alone can set you back more than that

Does that kit have break-in lube included?
