Onservation about magnum 5.9

I did it! Magnum 380 crate in a 74 Road Runner 4 speed with power steering. I used the early truck manifolds and an Edelbrock Performer 750. The driver manifold "kisses" the power steering box, but does fit in a 73/74 b-body. Yes, I realize that I am not getting optimum performance from the engine with both the carb and manifold choices. Believe it or not, I did correspond with Mopar Performance about my intentions at the time and they were supportive but stated their determinations from my plans and their advertising at the time did define the optimal set-up. 25 years later, I am still happy with the engine, it does have more power than my 340 powered Satellite but not more power than my 440 Road Runner.

As an aside, there were blurbs in Mopar Performance News at the time about the use of truck manifolds in cars and somewhere I have a letter response from MP stating the manifolds would fit my application.

I don't think the MP folks RE crate engines ever suspected people might use those factory truck and Jeep manifolds in "cars".

Of course they really only work in cars that have manual steering.

I'd be interested to know if that Borgeson steering box clears Magnum manifolds.
