Good cam size for stock 318 bottom on boost

Glad I saw this thread! Lots of good info in here! I have a 318 stock bottom end with a .70 a/r T3 turbo, needing a cam. I talked to comp cams and bought custom grind hyd roller with .490 lift w/ 1.6 rockers, 115 lsa, and 218 dur. intake/exhaust at .050. $340 and I can still use the stock distributor gear. Pretty good deal I'd say!
