[QUOTE="4sdvenom, post: 1564161, member: 13315"] I am not here to debate just state that my next motor in my Cobra will be a 96-99 Aluminum block. On the subject of NASCAR one thing that has been overlooked is that they are required to maintain a certain level of "production vehicle" standards......hence the term Stock Car! The bodies must conform, and have certain dimensions that coincide with the vehicle it represents. As far as motors go they must maintain certain "production pieces" albeit todays NASCAR engines are a far cry from a production engine, but the guidelines were set-up when a "stock car" was a "STOCK CAR", and even though they have been "tweaked" beyond tweaking to the $100,000 engines they are today they must conform to several of the "original standards, which were set-up to deter the highend exotic stuff such as aluminum blocks, 4-valve heads, fuel injection, etc. In order to conform they must be as previously stated Cast iron, 2 valves per cylinder, Carburated, Naturally aspirated, etc. Saying that "why wouldn't NASCAR wan't to use aluminum if it was better to promote more competition" is like saying why don't they throw on a blower, or a turbo!!!!!! They are not ALLOWED. But with the growing # of production vehicles using aluminum blocks, and multiple valves (more than 2) per cylinder it is very possible to see something of that nature in the future. Which is the whole reason Yates is pushing for the "cammer" engine to be allowed for NASCAR. There is an article in one of the Mags, about the development of the "cammer" with Robert Yates racing, and it goes into some of the detail regarding the rules for NASCAR engines, and where they are going in the future. :beer: [/QUOTE]
