Technical Edelbrock superduel

Getting ready to in stall this on my merc but not sure about fuel pump tower as the thickness of intake is thinner than stock manifold what is the right way to do this did a search and found nothing

 

Get the shorter pushrod that matches the intake.

 

Thanks does it change anything to oil pump

 

Measure the stock intake and stock drive shaft, then measure new intake.
Compare the two. Let's say the difference was one inch. Cut distributor drive shaft by one inch.

 

So if this is a Flathead Superdual. Intake height or intake period has nothing to do with oil pump.

 

I think he meant....
fuel pump, as he said fuel pump in a previous post.
