727 Big Block Info

...I see a leaky pan in somebody's future...Sealing a pan gasket is an art form. First you have to be a body man to straighten the pan; actually, knocking up the area around the holes to preload the area between them; at least 1/16"... Check it with a straightedge. Then choosing a stiff fiber gasket; Duprene brand... NO SEALER of any kind. No oil allowed on the contact surfaces; clean and dry. Bolts TIGHT. Just don't strip the threads out of the aluminum case.
