I was wondering has anyone put a compg cam or any othet brand cam with 268-272 and if so could you tell the diff between the stock one? Im puttin a new cam in my 87 camaro 350 edelbrock performer intake and edelbrock carb 650 with 74cc heads and was trying to get a good cam its a daily driver but i want more power than the factory one. The motor was rebuilt about 25000 ago im not sure if the pistions are dome or bot
