Restoration / Re: Breaking in a motor
« on: January 15, 2006, 04:39:00 PM »
Well guess what my Father and Uncle and me did yesterday, just broke-in the solid lifter 427 motor in a complete rotisserie restored 69 Yenko Camaro clone we just finished for a customer. This is the break-in procedure for all chevy solid lifter cams.
1: set ign. timing on no.1 cyl. readty to fire
2: prime engine oil system (we use straight 30 weight non detergent oil for engine break-in)
3: make sure valve lash set.
4: re-install distributor set for no 1 ready to fire
5: do not install coil wire.
6: turn engine over with starter making sure engine developes oil pressure on your oil pressure gauge.
7: adj carb idle air bleed screws 1 1/4 turns out
8: adj. carb idle screw to 1/2 t0 1 turn above base idle adj, you are setting engine to run at about 1800 to 2200 rpm after the engine comes off the fast idle cam.
9: you are now ready to start engine (install coil wire).
10: start engine. if above have been done properly all things should go well
11: start engine and run for 15-20 minutes at 1800 to 2200 rpm.( do not rev or change rpm level above or below the 1800 to 2200 rpm. at this point not necessary to adj timing or set carb. these things will be done after cam break-in.
be sure to watch engine oil pressure gauge and water temp. do not let temp go over 200 to 210 degrees and check for leaks (oil and water). After 15 to 20 minute break in period shut off engine (stalling motor is better than key turning if its a manual trans), let engine cool, check and top off radiator. drain oil, change fillter (add new oil and filter whatever your owners manual recommends) set engine timing, re-adj carb and re-adjust valves to proper valve setting.
any questions just post or email.
