360 cam choice

I agree with MRL, defenitly not to big. I see no issue with running that cam. In the future, be it RHS or Edelbrock heads or simply porting what you have, the improved cylinder head flow will add a nice and noticeable power increase.

With your current stock heads, check the clearances with the retainer to valve seal and make sure the head has room to run that amount of lift. There should be no issue with clearance, but just check anyway.

There should be enuff vacuum to run power brakes without concern.
