As you well know by your multi-page thread on 318 cams. (dartfreak75) There are many (did I say "lots") of threads here about 318 cams. Use search function and read along. You will have to sift through the information but remember, 318's are easy to over cam without a higher stall torque converter and a higher numerical rear gear to make them work. You want street performance from idle to 4000 rpm? Don't go big. That's why I recommended nothing over 220°@ .050.
