Dead stock bottom end quickness

I am really interested in this thread. Currently in the process of rebuilding a 1972 360. The "J" heads are off and ready to go to the machine shop. I have purchased a windage tray and adjustable rockers from fellow FABO members. Hoping to leave the bottom end stock and get 12.40`s out of the motor. Cam suggestions??

Call Brian at IMM engines, tell him what you want do, and you will not be disappointed. He will give you ideas for the build, and he can spec you a camshaft that I gurantee will do what you want, and if it can't be done with the parts you have (which im sure it can) he will tell you straight

good luck
