Title: Tranny T-case Help
Post by: MadFord on August 02, 2011, 02:35:56 AM
I am looking for the best transmission - transfer case combination for my set up. I run in competition bogs in my area that range from 100 to 115ft and 2 to 3.5 ft deep. The truck will be under the knife this winter so I am preparing for the rebuild.
Current Setup:
'79 K10 short bed
Gutted bed, cab, front clip
358ci chevy sb 10.5-1 comp.
sm465 with np205
Dana 44 front and 14 Bolt with 4:10s
39in or 38in boggers

Now I am currently building 408 chevy with 13.0-1 comp, 215cc (2.05-1.60) dart platinum series heads, scat rods, valley and main girdle, full roller assembly, etc. It 'll put me around +-600hp and 600+ tq. So I am dropping quite the coin and don't want to be trying to grab gears. Now hears the question, I have a th350 that I can have rebuilt to my standards and what t-case should follow np205 or 203. Help is appreciated.

forget the 203, they suck, i have one, the 205 is really strong, but another option you should concider is teh np208, it has way better low range

The problem with a 208 is its chain driven and it requires a slip yoke. I have seen a few break in stock powered rigs.

I say  np 241. I run one in my 500 hp truck with 44s and beat the crap out of it works great!

350/205. build the trans strong, and that gear to gear 205 prolly wont break. my 205 has held up, i just break axles now loll

and you can get a Slip Yoke Eliminator for the 208/241 i think

NP205 is about as good as they get without getting into big $'s. I've put well over 500 ponies, and 750lbs torque through em' without so much as a hiccup.

Quite honestly...................whats wrong with the SM465 Np205 you already have?????................that stick trans is a hell of alot stronger than any auto trans you could put behind that motor of yours............and you already got the strongest T-case.


The 205 might have a shittty low range  of 1.96.............but your 6.54 1st gear will more than make up for that.

True..........but there is such a thing as SPEED SHIFTING.........although the SM465 is not close ratio........lol

another thing we all missed is that if he wants to use teh 205 he has he's gonna need a th400 not a 350, or he'll have to geat another 205
