After deciding in which car I wanted to put this engine, I ended up deciding for my 1960 Chrysler NewYorker.

The complete ‘the picture’, a pair of original early ’60s Chrysler Long Ram intake manifolds were installed on the engine. This ment however a couple of things on the engine had to changed before this would fit, like factory valve covers for instance. Also decided to change the UltraDyne cam for a much milder hydraulic cam, which would work better with the long ram intakes.

At first a camshaft was chosen which I had laying around (Ultradyne mechanical cam, 255 @ .050″ w/ .582″ valvelift) but this was changed later for a mild cam that worked better with the LongRam intake manifolds.
Then again, 2 years later I decided to run a solid roller cam in the engine.
