I have a freshly reabuilt 355 four bolt with an edelbrock performer intake, edelbrock 750 carb, double humper heads(stock specs.), headers, i was wondering what the highest cam lift i could run w/o out damaging anything.

 

Out of curiosity, how are you bolting your accesories on ? Oh yea if your running original springs thats not very wise, because like everything else thats old and abused, their worn out. If you want to run a decent cam you should install better springs matched too the cam.
