I've got a Shaner S3 tb which is heavily ported. I'd say it's about 78-80 mm. It can't hurt to call the Holley tech help. I don't know their phone # off-hand.

I appreciate the flowers. You know, unless you have the Nick Williams throttle body I've heard the 90mm's give issues. The 80mm BBK's have casting issues, and the FAST tb's stick open/closed plus I've heard other lil' issues.

If you get a Shaner S2 or S3 I think you'll be much happier. There isn't a huge difference going from a Shaner to a 90mm especially if the same intake is being used.

The Weiand is really nice when you pop the hood and the prices have just dropped. It used to cost $8xx for the polished ones and now they cost $5xx
