Re: what's involved in switching my T350 to a T400 in my 71 K5?

I put a 500+ HP 496 in my K5 and even with a built TH350 it can't take it. I think it's worth the $$ to go with the TH400. will save allot of headaches and down time. As far as being "spendy" I'm so deep into this truck already it doesn't matter
If you have a TH350 in there now you already have the coupler.

Good luck with your project.
