Hi, I have got a 78 Camaro with what appears to be a 76 truck 350 engine. The car has a set of Summit ceramic coated long tube headers, 2.5 inch duel exhaust with a H pipe, T350 and 2.73 gears. Originally I was going down the vortec path however I have decided to leave the stock heads and go with either and Edelbrock performer or performer air gap and 600 Holley. At the end of the day how much power do I really need. After reading much (weeks) information on cam choice I have brought on much confusion as to what would best suit the above configuration of my car/engine. I am leaning towards either an edelbrock performer 2117 cam or a comp cam 268H however this choice is not set in stone. Any suggestions and thoughts would be appreciated.
