Ok I hade a problem with my gearbox something jammed it up so I split the case was going to put a vitos +3 crank in it since I have a Vitos 240 kit well I just found a parts blaster that is coming with a +4 hotrod crank so I'm going with that I know the cases need machining and it was saying machine the head but will that need to be done with a 240 kit plus should I run the spacer plate from vitos like on there stroker crank
