hi, ford made a 400 HP try-power 430 in 58, they're rare and very expensive. edelbrock made a small base carb try-power intake and 6x2's log, weiand made 6x2's log a blower intake. crower u-fab made 6x2's and 8x2's. check with the cam companys, i've found that some still have billet cam blanks and will grind to your specs. fordged pistons were made by a number of companys in the 60's. a 2', 4 hole spacer, 4 hole adaptor and a big carb on a stock intake and a set of big tube headers will give you a lot of torque, that's what you need for truck puller.
