I just put together an engine for my race only car. Aluminium headed 360 12 to 1 compression with a solid flat tappet cam around .670 lift and duration at 265 at .050. I just broke the cam in by running it for 22 minutes between 1800 and 2500 rpm. I vary rpm during cam break in. I just installed the inner springs, anything else I should do before next Sundays race? How do ya'll break in a race engine?
