Hey guy's,

This thread has me very intrigued. I received my kit last month and have started to research the motor. My feeling is that I would probably be better off looking for HP at higher RPM rather than a big torque motor. It must be tough getting the power to the ground in these things...

Anyway, I believe I will be looking for a 408. I plan to run a dry sump system and a crank trigger ignition. I was told I should go with a smaller displacement if I want to see 7,000 rpm. I understand a lot has to do with valvetrain, but does the rotating mass of a stroker limit you? I read about beehive valvesprings recently, are there any advantages with them for high rpm?

Does the Keith Craft motor come with a dyno sheet? Do they have a similar motor with a little more cam & solid lifters?

Sorry for all of the questions, but I am new to the Ford products. I have always worked on Pontiac's. It will be a trip to get over 5,500 rpm!
