wich brand stroker crank is the best

hey man i saw your post about making a engine with 50 horses now i want it to ! i already have a brand new ct kit i'm now searching for a spare engine and a good crank. you think +6 is better then +4? i know a good porter who can mach up cilinder ports and cilinderhead
 
your cases are paper thin with a +6, the motor Im getting ready to build will be a +4 with a 115mm rod. better rod angle and much more flexability setting the porting up as there is plenty of room to cut into the head and play with the spacer plate (to make up for longer rod) thickkness
 
nice ! i found a second engine!!! now i only have to have a +4 stroker can you tell me wich brand i should take?? i need the best available i drive on public roads long straits so the bigend gets a hard time!!!
