I was thinking of buying the Holly proJection for my blazer (its got a Edelbrock 750 carb) My problem is that it sais it's only good to 275hp and I have a GM 350HO crate motor with 300hp in mine, not to mention the Crane gold race roller rockers headers, air gap manifold, ect, wich probley bump up the hp a llittle more. If i do get this kit, will it kill my HP a lot? Since it's a 2 barrel kit I assume it will give me a lot better low end and mabey some mid, but I guees i just dont want to choke my 350 !!! Any input??
