I want to know about this, i have never ever seen a 421 just bolted toghter and throw in a chassis and run 3.8s.
Little more detial might help some others understand how this can be, like is it just straight out of the box on alky and in a drag chassis?
Not saying it cant be done but i myself have never heard of it and or seen it "dont get out much", i know Jasons 397 runs its azz off....so i know alot can be done to little motors to make this happen.
Not saying your lyin just asking.....inquiring minds would like to know.
