alright lets not take this to the pitstop because i would like to see everyones very different opinions on what they think is the best way to break it in.... and then i want to see who's engine lasts the longest!!!! haha

Ohhhhh puuuhhhhllleeeeeeeeze. Frickin' topic has been beaten to death on here.

Heat cycles for about 200 miles drop oil and onto the dyno. Running fine so far 3500 miles to date.

yeah i know theres more threads on this topic than the "what color valve covers" topic.

buuut, i DO wanna see people think they know whats best, then i two months see a thread with holes in blocks...

my opinion on breaking in a SB: drive it like you stole it... when you break something, its then considered "broken in"

After the rings seat.

BTW, I waited 15,000 miles before I switched to synthetic!

That Mototune method is the one I used for my old Turbo DSM and it worked like a charm. 180psi compression across the board after 500 miles. Shit I took that beast to the track the night after I put the new shortblock in it and ran it 3 times, had maybe 75 miles on it by then.

 

[Mr. Q]

fallen, no long term side effects to the dsm?

Ran for another 20,000 miles at 23psi ~400whp with me beating on it everyday with no ill effects. Had an accident that totalled the car a few years later but I am confident it wouldve lasted MUCH longer.
