My 400 sbc survived the cam break-in!
I broke in the cam with valvoline vr1 20-50w and a bottle of lucas break-in additive. I was sweating it big time! The cam is a flat tappet .575 lift 250 duration @ .05 on a 106 lsa. 11.7-1 comp. As soon as the engine fired I revved it to 3000 rpm. I fluctuated the rpm from 3000 to 2500 for 30 min. This a budget type motor. 200 cc heads, flat top claimer pistons, stock crank, eagle rods, msd ignition, dual edelbrock carbs.The more I work with the edelbrock carbs the more i like them... I ran the motor on 110 octane gas. We have about 30 guys in our car club that all use this form. Thanks for all the past help!
