400 stroker or 440

thats a tuff call. i built a 431 before any affordable stroker kits were available. the crank work is expensive, the pistons were custom only at that time. i think it does make a big difference in the characteristics of the engine. the piston is almost half the wieght of a 440 piston and im onl 9 cubes short. the stock ly rods have a better chance of surviving with the light piston. the bearings will be happier. im just not sure its worth spending the cash to do a 451 dollar for dollar when you can go withthe 440 source 4.15 kit. either way, its going to cost a lot more than a stock type rebuild of either a 440 or 400. if you arent hitting the track all the time, is it really worth the extra expense of a stroker? do you want to run power or manual steering? whats the budget? there are a lot of things to consider.
