410 Help!!!!!

be carefull with that engine. as you probably already know that engine was only made for two years and the parts are becoming harder and harder to find. as for the engine it self they came with the 428 crank and the pistons are different between 4 bbl and 2 bbl versions, so make sure that you order the right parts when building your motor.i built one for my truck, put a cam in to it and went with the ajustable rocker arms and some dist work, carb and it was a stump puller to say the least. almost pulled the tires off the ground with a 4 speed. also had a set of very low gears 613's if i remember right. and it got around 13.5 mpg. but it was done at 55 mph because of the gears but it was fun to drive. also make sure that you don't forget the baffle under the intake when you build it or you could have oil problems good luck and keep us posted as how you are coming along with it
