Sal:
I am running the "Cobra" marked nodular iron bellhousing that was one of about a dozen units recast by Wedge in Southern California and sold thru Motorsports International. I am assuming that you have the same unit. The original units made in the '60's were NHRA certified and were marked accordingly. The contemporary replica is not certified and thus not marked as such, but is identical and like the original is beautifully machined.
I decided to use the Wedge unit for a couple of reasons. First, for authenticity. Second, for fit. After mounting, the concentricity dialed out at +/- .001" without any alterations and the overall fit was spectacular. The only issue I had was that I was not able to use a diaphragm style pressure plate, because the inner dimensions of the bell would not accommodate the height of the pressure plate's "hat". You may be prevented from using a multi-clutch set up for the same reason. I went to a McLeod Ford style three finger pressure plate, single disk, McLeod hydraulic T/O and couldn't be happier with my decision. Clutch operation is smooth and precise, without the hard pedal effort that a three finger setup is often associated with.
A Lakewood will hold up to most everything, but there is no guarantee that these nodular iron units, as robust as they are, will do the same.
I guess it still gets down to what makes you comfortable.
Hope this helps.
Bud
