nuc_welder Posted October 12, 2008 Report Posted October 12, 2008 Ok I'm wanting to build a 421 cub motor this winter, prolly gonna use vito's sleeper cyclinders, stoker kit, and 8+ pistons. I found a chariot performanse cool head on ebay fairly cheap, just wanderin if that head will work with my setup? I know i'll need some domes to go with it, I'm using 118 race gas, just curious what size dome I need to start out with? Quote
Wildcardracing Posted October 12, 2008 Report Posted October 12, 2008 Well, where do I start? If you want to build a 421 cub then you'll need a set of 68mm CP cheetah cub cylinders and a +4mm crank, not the vito's cylinders. The Vito's cylinders do look as though they should have some pretty good potential with a nice port job, but I haven't had the opportunity to mess with any yet. As far as the Chariot head, yes it will work for your application, your dome size will depend on your altitude. The Chariot head uses Pro-Design or Noss style domes so they will be easy to find. You will need to also select a set of domes that have been cut for whatever bore your cylinders have. What kind of riding do you generally do?? This is important because a cub is not the best for trails, it is more of a drag or aggressive dune oriented cylinder. Quote
nuc_welder Posted October 12, 2008 Author Report Posted October 12, 2008 Well I do some dirt road drivin, but mainly drag on the highway. One of my riding buddy has a 4mill stoker with stock bore, another one is buildin one with atleast some 404 big bore cyclinder, and not sure what else. I just want to be able to beat them! Quote
nuc_welder Posted October 12, 2008 Author Report Posted October 12, 2008 Oh yah my elv. is about 500ft. Quote
GrMeyer Posted October 12, 2008 Report Posted October 12, 2008 why dont you get the 4mil and have someone on here port your jugs for you and then gear it and ride the shit out of it? Oh ya and save money buy switching to geico :biggrin: Quote
Animalman294 Posted October 12, 2008 Report Posted October 12, 2008 My cubby's got 19's............ Quote
m.parker Posted October 12, 2008 Report Posted October 12, 2008 Oh yah my elv. is about 500ft. Sounds like you need to find a CP cub dealer in your area and let him set you with a 421kit. :thumbsup: Quote
J-Madd Posted October 14, 2008 Report Posted October 14, 2008 There were some 421 Cub cylinders, pistons, and head/domes on planet sand for $600 the other day...just add crank. Great buy if its still there, Quote
