running crower 60916 221/229 cam in a 406 with home ported 13's, never been able to get the power out of this combo--275rwhp 315 tq that it should, since that dyno i have home ported the heads added tri y headers (tried adv cam--lost power on same dyno), question is im only at 9/1 comp would bumping that up to high 9,s be worth the hassle and cost. im going to add 3.73 gears--have 3.23 now with 28in tire so it should feel better.
