Jack21 i would like to know any of those secrets MSD is telling, i am running the MSD setup and i dont think you will gain anything from switching you are already running a good setup. if you dont have the new edlebrock air gap intake you should consider switching that out in almost every test so far the air gap intake did better than the old performer RPM and even the victor jr intake. for average power and torque. that said you should really dyno the car then play with the mixture and possible timing to get everything out of you engine. we just installed a new Dynojet dyno here is east Texas and so for almost everyone has picked up 10-20 min hp and torque with correct carb adjustment and timing changes . one guy made 50hp more when we pulled his carb from a reading of 10 on the A/F meter to 12.8 and on the juice it was over 100 HP. so keep tweaking but you may want a plan and a starting point or you could make things worse and spend money doing it.
have fun. still tweaking my 351, considering the stroker my self.
