Technical What 8BA cam is this??

  1. I just posted this on the Ford Barn, but thought I'd post it here too. I have an 8BA cam that I degreed and came up with the following specs: Does anyone know what it is or how it would behave? It looks like a regrind since the base circles are even with the core.

    Intake open BTDC: 19
    Intake close ABDC: 53
    Exhaust open BBDC: 62
    Exhaust close ATDC: 17
    Intake 0.05 Dur: 252
    Exhaust 0.05 dur: 259
    Intake Center: 107
    Exhaust center: 112
    I/E lift: 0.400"
     
  2. Very similar to a 400jr, it will be lopey and will not wake up until the higher RPMs. That being said, my merc engine has had a 400jr in it for 13 years and it's been livable though mileage will suffer. Upgraded intake, new heads, mutli carbs, and upgraded ignition are a must though, a little mild porting wouldnt hurt either, at very least port match the intake and exhaust.
