The same thing happened more or less, so the tractor ended up going to europe and being sold in the mid 80-s.

But they never did find the nitrous bottle that was hidden by the water tank, built around it. It was hell on crankshafts and blocks.

The project head I mentioned was a single cam and only twin t-17s in series which was the norm then.

In the pulling world here is a neat head if you got deep deep pockets.

I recall 1n 79-80 when this started it was just a block of al. and a old bridgeport. At the time it was just a few hours a day between jobs and didnt seem that big of a deal or project, but it was.


This head is said to go over 500 cfm and then add two big turbos....I dont think a head like this would need any cleanup work.








My cousins built John Deer pulling tractors years ago, they built a dual overhead cam cross flow head for one. Then NTPA outlawed it after one season, said it wasn't a production piece as JD at the time wasn't a cross flow head. Heck I didn't think the three to five turbos were production either. laugh2
