Exactly, when I put my motor together for my old mustang, I started it, let it idle for about 5 minutes while setting the timing, messing with the carb, and looking for any leaks, backed it out and let it eat N/A. Loaded it on a trailer the next morning, took it to Atlanta, took it off the trailer, sprayed the shit out of it in front of the hotel, went to sleep, got up the next morning and took 2nd in the true street class, never had a problem with that motor. If it's gonna break, it's gonna break.
Edit: For those that don't know, true street involves a 30 mile cruise (break in
) and three back to back passes averaged together.

What needs to heat cycle? About the only part that changes with heat(other than oil) is pistons, are you saying the pistons need brake in too?

^^^ agreed.
Besides, Block temp increases pretty rapidly from the initial fire, it wouldnt take too much longer than a couple mins to be a prime Temp for the metal to be fully expanded

Are you joking? I don't get it huh? I guess paying all that money for a valve job was a waste since they wear in, rings seat in quickly and if not, alittle load will only speed there break in.

whaazup, Briggs blocks are shitty pot metal and there aint much to them, block movement is much more of an issue than in a cast iron V8. Plus, I'm assuming his V8 is the old block that was just freshened up so again, its moved all its going to.
Good rings are actually broken in while hand turning the motor over installing the pistons/rods and checking cam timing, it aint like the old days where you had to throw some baking powder in the carb to seat the rings.
On my turbo car, I kept out of full throttle for about 100 miles, and left the wastegate at its factory 8 lbs until about 250 miles, then it was 18psi and 6k rpms ever since.

I just took my motor apart i built freash and never broke it in i let it run 20mins in the driveway drained the oil put freash in then ran it to 130mph 45mins after i started it with all new bearings rings pistons,seals well i just took it out 3days ago it now has 1300miles on it from 6months of driving mostly high speed bridge and work driveing and man my bearings are still flawless the rings are perfect not one problem from it and so clean i think break in should just let it run for 30mins at idel then soft driveing for a day thats it well at least for a 4Cyl
