Would be nice if bd made a drivers side and passanger side kit as ld go with that. Haven't any any luck with tapped stock manifolds. Even the one that a machine shop drilled and tapped. Has a small crack after 6 months. None of them leaked alot but enought to bug me.

What size are you tapping them to? 1/8npt or 1/4?

I've never had one crack, at 1/8npt

..

1/8" npt. The cracks aren't huge but enough to bother me . Just one of those things where I feel it is worth the money to upgrade while it is already apart for a upgraded charger. Usually I could careless about the price but I will be having another back surgery here shortly so any money I can save will help me while im down for 3+ months again.

You'd be surprised but that is exactly your issue. NPT is a tapered thread. The farther you tighten the fitting in the more force it is putting into the manifold to try and expand the hole causing internal stress in the manifold.

I didn't put a bunch of torque on mine and I never had a problem in 40k miles cracking or backing out.

How mad is Brett going to be if it's faster than the C10 :rofl:

It won't even be in the same ballpark since he has been 8.34 @ 4500lbs and I am still going to run an Allison and this truck has only been 9.06 so far. Brett has dropped a ton of weight and is picking up a ton of HP! He will go deep into the 7's quickly and I hope to be able to break into the 8's with this beast but have a lot to learn with it.
