I have a new roller cam on a fresh but broken in 400 SBC.
When I fire up the engine, I seem to get rather loud lifter noise. But after two miles, it fades away. It sounds like only one lifter. Driving around, engine up to temp, the 400 sounds completely normal and healthy.
If I let the car sit for an hour or two, the lifter remains quiet.
I’m betting after an overnight, it’ll make a racket again, but I’ll check tomorrow.
What would you do ?
Also...
When would you change the oil and filter ?
