banshee 268 Posted March 8, 2010 Report Share Posted March 8, 2010 hi i was just wondering if i had to do the stroker crank with the 421 big bore or if i could just bolt it on.also do i have to have the cases bored out for this kit also and would this big bore be any good for circle track racing and ice racing.if not what big bore would be the best way to make big hp Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted March 8, 2010 Report Share Posted March 8, 2010 you can essentially build any kind of setup to be as big as you want. the possibilities are endless.. there are a few however that are cheaper and make awesome power.. it sounds to me like you need to go with a 4mm cub which is a 421cc motor. the crank drops in without any modifications.

boneyardbanshee. Posted March 8, 2010 Report Share Posted March 8, 2010 Yes, thats what makes it a 4mill. With smaller engines you will not gain tons of power on bore size alone. Thats where the stroke comes in. Now on a large V8 sure, but there are alot more pistons, and they are larger so they all add up to make the large power increase. Make sense?

BSHEE400 Posted March 8, 2010 Report Share Posted March 8, 2010 enough haha i don't know it's never been dynoed, it could make a lot more if i switched to cpi pipes which i really want to but i'm too cheap because work is slow at the moment if i had to make a guess i'd say somewhere around 65-70hp but i could be way off Quote Link to comment Share on other sites More sharing options...
