I am finally in full swing with my K5 project.

I have a 454 with a TH400 and NP205 behind it.

LOOKING FOR:

-ORD Doubler
-NP 203
-TBI setup for my carbd 454
-39.5'' Tires
-Possible Hydro steering
 
you will also need th400 to 203 adaptor and th400 output shaft to 203. your th400 to 205 stuff wont work with a 203 box.
 
Really? I thought that my th400 has a 32spline and the th400 version np203 has a 32 spline as well. Can't I just use the th400 to 205 bracket and re-drill the front of the 203 and bolt them up? That was my plan, hopefully I didn't missunderstand ORD's info...

Thanks for your help
 
all stock stuff no it wont. 203 has stubby output. but if drilling round 6 pattern then i think it will work. but it will be longer than stock 203 plate and stubby shaft. so if length is a problem best look for this. just wanted to make sure you got the right stuff. good luck.
 
Do you have the round pattern or figure 8 pattern on your 205? Also if its going into a K5 length is going to be important so I'd go for a factory 400/203 adapter and output shaft over redrilling the 203 to keep it shorter.
