01-30-2006, 06:04 PM
OK so I got this 429 to put in my truck soon hopefully. It was set up with a C6, I am going to be setting it up on my 4spd NP435. Which flywheel do I have to use? Will the one on my 351 M currently in the truck work? :confused:

no,429 are internal balance/351m is external balance

best to find one for a 429-460, a 390 flywheel will work, but the gear tooth count is out about 3 teeth so starter will make some noise but it won't hurt anything.

Nice. Didn't know about the 390 working. So I could probably change the bendix on the starter to compensate for the different tooth count?? Now I just have to find one!

390 flywheel works fine,you will need to get a pilot bushing made for the crank.on the 435 you will need to shorten throwout bearing sleeve,or it will bind on clutch disc spline.
