I am rebuilding the 460 and will put in the 73 F-350. I am also putting an HEI distributor in it. Can I just use a normal edlebrock air cleaner of the size that will clear the distributor cap. Or do I have to have the stock type with the air flow.

 

It should clear, if it doesnt just use a spacer as you have plenty of room under the hood of that gen. truck...

 

I found an open Ford Racing 13" chrome air cleaner that fits nicely. It uses the stock 86 460 ford F250 filters also. So easy to find & replace. On thing I did with mine was put a piece of tin about 6 " long in the front to keep the fan from throwing crap into the filter. It seems to help with filters not getting as dirty as fast.

Thanks, so it will run fine with the after market filter.
