Hello, I have a 1968 Shelby GT 500. I am in the process of building the 428 for it. I have some goals in mind and would like to also ask a few questions. So far, I am starting with a C7ME std. bore block that will not require boring. The engine block is at my machine shop getting prepped for the assembly. I would like to make between 450-500 hp. I don't mind a lumpy idle and the car is a 4-speed with a 4.11 Detroit locker. I would like to run a hydraulic roller cam and would love to hear about some of your experiences with hydraulic roller cams in FE engines. I am planning on buying a set of Edelbrock Performer RPM heads bare and let my machine shop finish them. How large can I go on the valves with a standard 4.130" bore? I have ordered the pistons which are Ross customs based on the Cobra Jet pistons. They have 1/16, 1/16, and 3/16 grooves. I am running plasma moly file fit rings. I have a Police Interceptor aluminum intake, is it good enough or do I need to use a Performer RPM? I don't think my horsepower estimate is out of reach. I will have the engine align bored/honed. It was slightly out of tolerance and I do not want to take any chances. I am using stock rods with ARP bolts. I am using ARP main studs, melling
oil pump, comp cams roller timing chain, clevite bearings, and the best parts I can afford. My main question is the roller cam. Does anything need to be done to the engine block to accomodate the roller cam? i.e. any oiling mods etc...? Sorry for the lengthy description, just trying to give as much detail as I can. Thanks, Todd
