Yes i used the 309C, but it took considerable frame clearancing to get them in
the way i wanted. I would go with the Headman block huggers for sure.

Hello Chris
looking at the pictures of your engine it looks like it sits about 1" higher than mine. I'm using the dirty dingo mount. I called dirty dingo to see what headers fit and they did not have a straight answer. I called Dough Thorley and their tech said to fallow the instructions. The instructions only call out motor mounts for 2 wheel drive truck and the engine sits 1.5" higher in a 2 wheel drive truck do the cross member for the front suspension. I will order a set of Headman block huggers and give it a try. I found a NV4500 transmission and the hydraulic clutch is internal so I won't have to worry about the external one I was going to use with the SM465. Thanks for all the trial and error work you did it was a big help for me.

Hey DWilber. Not a problem at all. That's why we're all here I guess. I got a lot of help from others as well. In the end, I don't think there's a manufacturer out there that will give you a solid answer. Too many variations in these engine swaps to make anything a sure bet and their not going to put themselves in the position of giving you incorrect information.

I do think these headman headers though will do the trick. If you dry fit them with motor mounts in place you will know immediately if their going to fit. There's really nothing in the way of their output except the motor mount and a very small sliver of the frame may need to be ground away. Good luck and let me know how you clutch setup and NV4500 work. I plan on doing this upgrade in the near future once I get mine driving on the road. A write up on what you needed to do would be great.

Thanks
Chris
