Anyone Running A 400 In Your A Body

oh BTW cast crank 400's are turds. swap out th crank for a 383 one and have it rebalanced internally. you will get more power and life out of her. better yet.. the 400 is the perfect race motor from Mopar. just needs reworked. the block is stronger than a 440 and it has a bigger bore and short stroke. not to mention it fits in places where a 440 does not. Find a 440 crank with the mains spun have it machined to fit the 440 block and you have a 450 10 cubes more just with a change of blocks and same crank. use a 440 crank and special rods and pistons you can get up to 470 Cubes.
