You've got to fire it up, immediately get the rpm's above 2200 (IMMEDIATELY!!!, and 2500-3000 is better) and run it for at least 20 minutes like this to get the cam and lifters broken in. You can't just fire it up "to see what it sounds like" for a minute or two. Hopefully you already know that.

yea pops is pretty good about that, i believe he is running a 264 555 cam, but his is solid lift,, i should have got a solid lift,, i am thinking of swapping my cam out for something a little smaller and making it solid. what cam would you suggest, i want it to sound eratic still ( your instruction above are your suggestions for my cam right)

The break-in instructions are for any and all flat tappet cams, hydraulic or solid. Cam choice I can't really help you, I never hot-rodded a 283( it's way too small

). If I was to choose, I'd look for something around 240- 250 dur. @ .050 and .500-.570" lift, 108-110 lobe seperation in a solid grind, and probably a straight pattern (intake and exhaust the same).

well i just got her running again,, clayed the heads to make sure they fit and they did. we started it up and boy does she sound like a beast. That damn cam make a hell of a lope. Time to fine tunner and get some miles on her so i can open it up.. Lay a john force burn out let everyone no who has the power,, that is until pops gets his back on the road. thanks for the help, once i get the truck washed and ready i will upload some pics.
