dajogejr Posted October 2, 2007 Report Posted October 2, 2007 Can it be done? and is it a sheaper than getting a new? who can do it? Sell your stocker and get a 4 mil. For the parts involved and price to do them, you can get a 4 mil...cheaper or just as cheap. The webs are drilled +2 mm of the center line in comparison to a stocker, no one I know will weld and redrill the stock webs, so they have to get 4 mil webs drilled....not worth it after that IMO... A good used 4 mil crank is 300 bucks, give or take. If your stock crank is in good shape, 100 to 175 bucks is what it's worth... Quote
patarol Posted October 2, 2007 Author Report Posted October 2, 2007 Thanks, the banshee has become a sience and i`m hoked on it!!! 4mil it is gona be then, with a cheetha cub :biggrin: is a 100hp in range with a 4-mil crank and a 68mm cheetha cub? thats my goal! but i still need the mid range, thinking of not porting the cub to keep the mid....

dajogejr Posted October 2, 2007 Report Posted October 2, 2007 Oh boy...here we go. Get the Cheetah motor with powervalve if you want mid range. Cubs have none. I had a 4 mil, I now have a 10 mil. They're great motors....but they have no mid. On a 10 mil 72 bore cheetah setup right, 100HP on race fuel is pretty easy. Quote

He he i know But i think cubs wil keep som mid with my FMF fattys and 28mm carbs? it cant be any less then my stock jugs with no porting? and they give me the mid i need. Quote
dajogejr Posted October 2, 2007 Report Posted October 2, 2007 No...they won't. I had stock carbs and T5 pipes on a 4 mil cub, and it still had NO mid with a lot of compression and a lot of timing... You're choking that motor....either get a power valve motor or build a stock port motor.... What you're attempting to do is build a 502 big block motor and put a 450CFM carb on it with 2 inch exhaust, a catylitic converter and restrictive mufflers.... I just don't get it.... I promise with small exhaust and small carbs it will not change the power band or delivery style of a 4 mil cub. I've done it. All it will do is limit the top end power...it WILL not, I repeat...it will NOT give you more midrange. It will be less than your stock jugs with no porting because of the port layout of the cub cylinder. It had drag port timings out of the box....there is no such thing as a DUNE port on cub cylinders. You can port more HP out of them, but it'll be upper RPM and peak HP.... Save your money, you're not ready for cubs to be honest if you're trying to choke them down. Keep in mind you'll need a better clutch and transmission help as well, and that's just the start. Longer rear swinger, reworked (stiffened) rear shock.... All that power does no good without being able to get it to the ground... Quote

I thuoght so, but needed it confirmed. i thought about the valve cubs but cant find any selling them, not even on E-bay, they al just have the cubs. also gona get the carbs 34mm PWK ++++ Quote
dajogejr Posted October 2, 2007 Report Posted October 2, 2007 There are plenty of builders that will sell you a Cheetah (Power valve) motor. Call one our our site sponsors, or Nate McCoy, Titan Racing, A&S Racing, etc....there are plenty that sell the Cheetah cylinder still.... Quote
