Thanks for all the replies. My car number is 362 so maybe the new one have a larger bore. I contacted Arizona Muffler Fabrication and he can build what I want in a couple of days. We have a very good exhaust fab company here in Sacramento that I'm going to check with first.

Thanks again for the info. I will re-post the difference in the chassis dyno numbers when I'm done.
