My 340 in my 66 developed issues :-(

I have manual steering and I'm not sure if the previous owner did anything to modify the steering shaft to accept the 60's HP manifold. But you can rest assured the manifold will fit. But you can't just try and put it on, or else it will not fit. You have to either have the head off, stuff the manifold down in position then put your head on and torque it (this way would be a *****) or, you can pull the motor and install the manifold on the engine then manipulate the engine into its sadle.

As far as the right side manifold; Gil did a bang up job!! He knows the areas to grind and you don't have to bang/dent your fender to make it fit. It slips right in like a glove!

I did have to clock my oil filter housing just right in order to clear the fender and leave some breathing room between the manifold and oil filter.
