- My 13 year old wants to build a 1971-73 Mach 1 Mustang for his first car. We have found a Grabber Blue with white interior base model 1971 Mach 1 to start on.
OK guys I just jumped in the deep end of the pool. I just purchased a complete 1973 Mach 1 Q code. I will be retaining the factory heads. My question is what aftermarket dual plane is the best for a mild 351C build? Edelbrock makes two Performer style intakes one for a 4V and another for a 2V. I know the Q code heads are 4V but can the Eddy 4barrel/2V intake be mated to the 4V heads? Reading the 351C forums the biggest debate seems to be that 4V intake volume produces a lack of throttle response and low end torque. On BBC's an old super stock trick was to use an oval port intake on a square port head to accelerate runner velocity while gaining throttle response and more low end torque. The heads will be treated to some 2.09 BBF intake valves along with some pocket porting, and other small performance enhancements.
