Chaplin,

It would cost more to rifle drill the block than the block is worth. However, these top oiler blocks are perfectly good for street use. If someone were to crawl under the car and see that the three plugs are missing above the crossbolts, they would know it's not a overpriced side oiler. I haven't found anyone, yet, who can squeeze under my car with less than 4 inches of ground clearance. So, this seems a very reasonably priced choice.

Cracker,

The ad does not say that it's a marine block. If it was closer than NJ and I were interested, I would write the seller and ask him. The good thing about a marine block is that they're rev limited to 3000 rpm. The bad thing is, it may have had salt water flow through it. The best castings were used by the racers, the second best went into street cars. The rest were sold to boat makers. There is no other difference between the blocks. The seller should answer these questions before bidding. If someone told me that it were not suitable for use in a Cobra, I would suspect that he has a bid in already! If you're building a serious race engine, you're right, this one will not do.
