Hi, this is my 1st time posting so please excuse any mistakes etc. I am looking for recommends on building some mild street performance to a stock 2 barrel 327 in my 1967 camaro base. It has a 2 speed power glide and 12 bolt. Also need to maintain vacuum for 4 wheel power disc brake booster. Didn't plan on adding a torque converter. Having said that, I'm considering adding vortec heads, 4 barrel carb and intake, choppy idle cam, and headers but need some thoughts on parts that will jive together and on a reasonable budget. I appreciate any input, thanks.
