Solid or hydraulic cam Alex?After the cam break-in don't be afraid to run it semi-hard, just limit the rpms. Definately do not go on a 500 mile road trip with steady cruise rpms. You need to seat the rings with accel. and decel. Race engines on non street cars get no street break-in time at all, just a couple of short shifting 1/2 passes.  SteveW

Prime it with a drill before you crank it, also turn the crank while you do this. I know this isn't break in, it's basically prelube, but i just didn't want you to forget that part.  good luck

I ran mine from 2,000 to 3,000 rpm for 20 minutes with a fan in front of the radiator to keep things cool. Took out the inner valve springs to keep loads lower on the lobes until they set. Vary the rpm up and down during the breakin. Don't let it idle.After that, 250 miles at <4,000 rpm without the inner springs. After 250 miles, put the inner springs in and ran it as hard as I wanted. Changed oil after initial and at 500 miles.

I'd only add that I ran 30W ND (non-detergent) oil for my cam break-in. Scott(69 Mach) spelled out my identical break-in with removal of inner valvesprings and a few hundred miles of 'easy' driving. Your cam/valvesprings may not require this procedure, contact your cam manufacturer for specific break-in info

A new car, you mean NEW straight from the dealership? New car engines are run in at the factory, just get in and drive
