Re: Fly Weights
A56 -
That's the story that has gone around, but the intake manifold casting number on NHRA's Tech Bulletin is the cast iron intake shown in the pictures on my last post. So I am questioning that the D4B has been accepted. If they can run it with no documentation, then that opens up a whole new set of worms. But, if the factory issued D4B has that same casting number, that's a different story. Does anyone know what casting number was put on the factory D4B?
