I/O rebuilt engine break in

[jasonnb]

Since I will hopefully be getting my 302 back together next week, what is the proper break in a rebuilt 302 V8?

I BELIEVE OPPROX 20HRS FIRST 10 AT NO MORE THAN THREE QUATER REVS,THEN A GRADUAL INCREASE OVER THE NEXT 10.AFTER STARTING NOT GOOD TO LET IT IDLE AT LOW REVS, TRY TO GET THEM TO 1500 AS SOON AS POSS.
