so, 7 pages later you are all still debating the legacy of the 413 and how it relates to the 440 prowess.

413's are not an economically efficient way to build hp or torque. if they were, there would be more of them on the road and more people racing them. that is the truth, and you can argue it to end of the earth, it still will not change the truth.

383 vs 400 arguments are the same way. people say 400's are crap, but all they are are just 383's with bigger bores. 440 is a bigger bore 426 which is a bigger bore 413 which is a bigger bore RB383...

which is better, who cares? which is special? they all are. Which one will give you the most bang for your buck when its a 440 vs a 413.. the 440. there, debate ended. now argue about something worthwhile and quit talking down to people just because they disagree with you. the only time you should look down on someone is when you are picking them up...
