My car, #1229 was a Hertz rental that still had the cast iron intake on the original engine. I purchased a S7MS intake a few years ago for my 'performance' motor. It was a Cobra lettered version made by Weiand. It has 4 individual holes as opposed to an open plenum.

The intake appears to be identical to the small block COBRA intake. Thanks, Larry B --------------------------------- Do you Yahoo!? Read only the mail you want - Yahoo! Mail SpamGuard.
