OK so I just ordered a 241/208 dubler (xmas present) from dd machine over on pirate, however since then another opportunity has presented itself and now I don't know what exactly to do. I have the opportunity to get my hands on a Caddy 500, and from what I've read over on coloradok5 I don't think the 241/208 dubler is gonna be able to hold up to the power at all. All the dudes on coloradok5 were sayin that the caddy 500 has stock almost 500ft lbs torque which I'm thinkin dual aluminum housing chain powered cases probably arn't gonna be happy about. Especially since my axles are geared to 4.88's and I'm runnin 44's. You guys think the dubler just isnt gonna be up to the task?

Also with that much power do you guys even think I need a dubler? I've had a couple people say that dublers arnt good in a high powered rig (even the 203/205 ones)? Course they were yota owners . . . . :D
 
You need to sign up for an English class next semester.
 
No excuses for the grammar, though?

You're going to split the 208 in half, BTW.
 
Actually I don't have enough $$ to get another engine worked it out as a trade deal, atlas costs way more than an engine anyway, lol. My main concern right now is gettin the 1 ton tranny swap done in my Z71, but I'm gonna just hang onto the engine till I get the Z71 all buttoned up so it might be awhile before I get started. I'm just wonderin if I even need to worry about a doubler if the motor will be pushin that much power.
 
I use to have a K5 and was on CK5 also. It all depends on what kind of wheeling you are going t odo. There are alot of guys on CK5 that have caddy 500 and a doubler. There are also alot of guys that have the caddy engine and no doubler because they dont rock crawl. From the pictures I have seen of your K5 it looks like you run mud. So no there is no reason to have a caddy and a doubler. If you are going to rock crawl with it then yes get a doubler. Post up on CK5 and see what they say. Just make sure you tell them what kind of wheeling youare going to do.
 
Well Why have that big arse engine with a doubler :shaking: I can not imagine when you would ever need that much HP in double low. Even running a V6 with a doubled case you could still develop enough torque to break just about any thing if you hammer it. You can get more power than you could ever need from a SBC, and the parts are cheap.:driver:

We'll that K5 is my buddies that I built for him and yea its pretty much a mudder, mine is a K10 pickup, basically cab N hood is all thats left. The goal for it is to be a jack of all trades type truck that I can plow throu mud with but at the same time still go do some krawlin if I want to. Might try the doubler then, not sure if I'll keep the one I have though, just don't see the aluminum cases holdin up long.

We'll the big engine is more for the situations where I wouldn't be using the doubler like mud and heck drag races and jumps if I'm in the mood to really break something, lol. Then when it gets time to actually wheel i can just go low, low and krawl. Course I really do not want to have to buy a whole nother doubler.

I agree that aluminum cases and big blocks don't mix. I have a buddy with an '82 F250 with a 460 and a BW1356, I think. I know it was aluminum because I saw it puke its guts while he was retrieving another stuck buddy. Ahh...a good ol' NP205 is worth its weight in gold at a time like that.
 
well when you get the doubler you could always take the 208 off hte back side, and install a flipped D300... which would be hell of alot stronger and still have the ratio... or maybe even adapt a Bronco D20 or 205 to the 241 case.... basically if its like most doublers, the 241 will just be the gear reduction front half with the planetary set.... so itll be strong enough, its the alum case and chain in the 208 thatll give u the prob


but that motor in super low range is gonna consistently destroy axles and what not if you cant keep the right foot off the floor
 
If you've got a 27 spline output on the range box, you're fawked regardless. It'll last behind a smaller motor and a ligher foot, but it doesn't have a chance in hell otherwise.
 
well now, the input of the range box, and the output of the front half arent ness gonna be the same thing.... so id get the input of the range box to go with whatever tranny youre goin with, and the output to be like a 32sp or something more common.... in my opinion, the only doubler thatll prob consistently stand up to big block torque will prob be the 203/205 one though....
 
yeah.... well if you get it im sure youll be able to resale it, esp if it has a desired output spline count like 23 or 32... so that most the transfer cases will be able to work with it, not just the rarer chevy stuff
