Bob lol

Get all your info and specs in hand and start calling cam manufacturers most will punch it in and see where you should be, need something that is not a drag car setup, then chose what averages out and most likely there is a shelf cam for you. Having head flow numbers of what they actually flow is a great start, not what the internet says.
