Brand new to the group. I have a 1964 Olds 98 with a 394. I want to do some Super tuning and possibly a hi po valve job if I take off the heads. I have spend hours on goggle looking for the factory Cam Specs for the 64 394 330 horse cam specs, lift duration, and LSA, valve sizes in length and stem size, and head C.C. of the 23 heads and how much they can be milled and compression increase. I really have looked hard for the information. Any help?
