Is anyone running the tall Ford racing aluminum valve covers on a 400? Crate engine is being shipped with those on it and got to wondering about clearance for the brake booster and AC box.
Thanks

 

I have the Ford Motorsport tall valve covers on my 400, with the large brake booster, and there is about 3/8" clearance. The booster has to be removed in order to remove the valve cover, but not a big deal.

 

They look great!!


My Mercury Marauder 410 4V factory lightning bolt valve covers have about the same amount of clearance between it and the booster.
Mine will come off without any trouble.

 

 

 

 

Thanks for the pics guys....was getting a little worried. 351M how much room do you think you have on either side. the ac box looks especially tight

 

1/2" I've been driving every day for a year now with no problems

 

Mine has had the tall Moroso valve covers on it since I bought it in '86. Thet are about as tall as the FMS ones ... I think. It was tight enough but they cleared both places. Never had to remove the booster or AC box but the covers have to be totally free and then slid upwards towards the carburetor like.
