Does anyone make motor mounts to lower an engine?

Thanks for this info, Clois! It may well solve my problem without necessitating adjustments to the parallel 4-bar rear suspension to re-orient the pinion angle. I do have an inclinometer somewhere, so I can make the adjustment if needed, but lowering the engine and transmission equal amounts may well negate the need for that. I have asked a friend from the GT40's forum to pull parts at the Ford dealership in which he works and see if there is indeed a difference between a sedan and convertible.

Thanks for the suggestion, Jerry....this was the route I used when I lowered the 351-C in that Maverick.

I've done the math and according to Edelbrock's pad height formula I need 0.775" additional clearance to switch out the intake manifolds only. If I can get 0.5" from the convertible motor mounts and 0.25" from grinding some material off the motor mounts, perhaps there is enough clearance to make the switch....I can grind off a new set of motor mounts and put them on the Cobra without removing anything and check the new clearance dimension with some modeling clay before I even need to order the manifold.

Just curious, I do have a Holley 600CFM vacuum secondary carb....does anyone know off the top of their head whether the Holley carb is "taller" than the Edelbrock? If the Holley carb is "shorter", I could gain additional clearance by switching out the carb...I just hate to do so if I don't need to absolutely do so, the engine runs so strong with the Edelbrock, no bogging, no problems of any kind.

I stock these and can post a picture from work on Monday.

Thank you, Mike....do you also stock a 9" dropped filter model? Actually, all I would need would be the dropped base plate as I already have the 9"X3" K&N filter and the X-Stream filter top. I have resisted using a dropped base b/c I figure it will result in increased restriction, requiring the air to make a sudden change of direction, but if all else fails I think I might well be able to manage with the additional filter area of the K&N's X-Stream filter top. The current filter really fills out the area under the hood scoop, so I'm not sure how much flow I can count on from the X-Stream filter top with it being so close to the underside of the hood scoop.


I'll have to check out what effect the 3/4" drop has on the headers....that may be a problem or it may not. I can shim the "rear mount" where the back of the headers attach to the frame easily enough.

Thanks for the suggestions and information, all....anyone else have any ideas?

Cheers from Dugly !!
