Stroking the 400

Can it fit, If you buy the top dollar callies, it will need a little bit of clearancing..However, the crank that long puts so much side load into the piston that you loose a lot of power, generate a lot of extra heat, and wear out the bores/pistons very fast..Definately NOT a street engine. You would be better off buidling a snottier 451(400 w/3.75 crank) and runnig that..There are many of these running around now, and the combo can run very fast if built well, and still be streetable for most people.
