i know alot of people may pul the money flag but in all honesty, a v-8 is a v-8. go ahead and build a windsor stroker...they will both have to be machined...then if you build your 302 to a 306 youll want some new rods and definaly new forged pistons. so your looking about 600-700 there....by time you buy all the hardware and get the crank worked with if need any....you can buy a nice 408 kit or 393 for like 1000 bucks with nice i or h beam rods and forged pistons and brand new crank...then just buy some nice heads and youll make your goal with ease... not to mention the strength factor with a windsor and the room to grow ...depends on how big your intentions are for the future..just my thoughts
