Re: good overdrive tranny??

350 shortest then 700 few inchs longer then 200R4 even couple more inchs longer.

Call Hughs or TCI and tell them your engine setup, camshaft specs all mods to your engine, rearend ration and aproxemate weight of you truck and they can set you up wit the correct stall converter this pretty critical of you vehicle with not idle in gear will pull the RPM of the motor down to far and motor will be slobbery and hard to keep idleing, most cases you are recommended a to small of rpm stall and you have to idle the engine to high at idle for it to engage into gear harshly and motor pulls down to much and loads the engine to much to idle sufficiently. which you have no stall anymore, you want the engine to raise a proper amount of rpm them move the vehicle to less of stall and you let off the brake and off she goes, my 2100lb 28 ford coupe hotrod has a 2600 stall and is to low for the engine setup and always have to shift the trans to neutral at a stop to clean the engine out cause the big cam loads up the motor with to much fuel at idle and want to try to die with idle set the high it is you shut the motor off hot and it diesels on me, have to keep the trans in gear then turn the key off and it stops the motor immediatlely.

700R4 will not bolt in exact length place as a 350 you have to shorten your driveshaft!!

If you look up conversion kit from 700R4 to a 350 for like a 4x4 truck *which years ago was a popular conversion cause the 700 was way more expensive to overhaul and a lot of people really didn`t like them), the kit comes with most importantly a spacer that goes between the rear case of the trans on the 350 to keep the factory transfercase adaptor or transfercase to stay in the stock 700 location cause the 350 case is Shorter and/or you could use a output shaft from a shortshaft 2wd and cut about 2inch off it or use the supplied shaft if you don`t have one to cut down and all you 44x4 drivelines would stay the same the tranfercase linkage doesn`t have to me modified etc......


Good Luck, Wildcard
