Pulled them out of storage last year, pulled the top off and found this mess. They had been sitting for a decade and had been fine when pulled off the car.

Units are 4758S and 4761S 500's and worked fabulous on my 440.

I had one of two plans- Take these two, strip them down to the bare castings and load glass bead into the sandblast cabinet and see how they clean up. $100 worth of kits and floats and let'er rip.

Or just simply purchase a pair of reman Edelbrocks 500 or 600 cfm from Summit and call it a day.

Thoughts?
