I looked around and I have 2 holley vac sec 750's identical. Is this too much carb. I pulled off my heads and I just found out I have a .60 455 olds. I will be going bigger on the cam. I have the tunnel ram. I have some carbs. I really dont want to buy new carbs because I have these 2 already and they are in very good condition(1 brand new).
thanks for the help guys,396
