I can't find my 2004 rulebook...

So the inlet location requirement was removed in 2004 or 2005.....

Because B-O-P and Cadillac that came from the factory with a front inlet now could run a side inlet carburetor.....

Edelbrock only sold side inlet carburetors...This rule change greatly increased their market......

The oldest rulebook that I can easily put my hands on is 1995 and at that time it was restricted to the size, inlet location and external appearance. Computer carbs could be replaced with non-computer with the same size bores and venturi...

Hope this helps,
Bob

Note..The Caddy was side inlet.The A/C compressor was in the middle front..
Carry on, Bobbo
