I'm building a 400M motor for my '77 F150 Supercab and I like some recomendations on where to go for best service and prices. I called Continental and was quoted $1000 for the shortblock. I also am using some custom parts like ARP fasteners , 9.5 cast pistons and a Comp cam so I need a place that can get these parts without costing an arm and a leg. I'd also like to run the motor on the Dyno at ABS to break in the cam and rings as well as tuning (the motor will be propane/gas). Has anyone dealt with them before? I've heard good and bad things. Thanks
