Do some roller piston rings. Less friction, more power, less break in.

Break in oil

I was discussing the flat tappet engine issues with my local engine builder and how the new crop of lifters are garbage and he told me he never has any issues but he breaks them in with lighter springs.
It makes sense and I don't know if any of you does that but I think it's a great idea
Most of the manufacturers won't warranty the tappet cam if you don't.
However, changing valve springs back and forth cost time and money, that could be spent on a roller cam....

You know me everything I have now is roller cam, I am just learning more stuffMost of the manufacturers won't warranty the tappet cam if you don't.

I really don't cam anything that needs more than stock pressure springs.
But I haven't broken in a new cam and lifers in years

Once you go roller, you’ll never look back!
Plus you can get way more valve lift with less duration than a flat tappet.

At one time I had 1.6 ratio rockers on this engine. Forget why I switched back to 1.5
This is a bigger benefit than the reduced friction people talk about. For crying out loud, we run big transmissions, T-cases, and axles, giant tires and heavy trucks. We don't have the right to say that friction matters.
What’s the word on the first oil change with this stuff? Wait 400 miles or change it sooner?
I change at 100, then 500 then run it to regular changes.
Changing at 100 gets most of the breakin wear, minute pieces of lint, dust, and break in lube trapped in the filter. Use more break in oil!
500 mi gets the finer particles of break in wear, and parts should be fully mated. Switch to your engines required long term oil after that.

Sounds reasonable.
I need to drive more. 20 miles a week is going to take a while to break in.

Why don't you get on the freeway half an hour each way 80 miles in one day.
Change the oil and filter, go one hour each way 150 per day.
3 days change the oil you're done.
For the record I did mine in 2 days.
First day 100.
Second day 300 and I called it good
Much as I would love to have that much spare time in my life, it’s not a thing. Kids, sports, chores, work, doesn’t leave a lot of time for random hour long trips.
yeah and you still need to do some ring seating, gradual accel-cost-accel, I thought Texas was full of back roads ?
Get that crap out of it YESTERDAY dump in whatever you plan on using, I'm an Amsoil guy, and drive it like you stole it !!!
Parts of it. There’s a couple around here I may hit up this weekend.
Why?
I feel all of this pain
BP Driven is widely acclaimed as one of the best products on the market at the moment, including by lake speed Jr
Google it
Actually I change it quite fast, basically after one dyno session or a maybe 1 or 2 quick street drives assuming you put some cylinder pressure in there to seat in the rings and didn't baby it. Sometimes I change it before the dyno session is even over if I will be adding nitrous or something toward the end.
The sooner you seat the rings the better, do not wait. If you haven't seated the rings in yet, do it the next drive, then change it to whatever you are running in the long term.
Don't use modern emissions oil in it, get some racing oil or something. I use Mobil 1 15W-50, or Lucas Racing Full Synthetic. Don't use Mobil 1 5W-30 or something, its not the same additives as the 15W-50.
If you want some 10W-30 or 40 depending on what they set your bearing clearance at, I can send you some Lucas Racing Full Synthetic if you need.
Being in TX I would just run the 50 wait and see if your oil pressure isn't too high.
