2.7 on dyno

[Two Oh]

Had my engine on the dyno today.
Replaced the SSI's and the sport muffler with set of Porsche factory headers with megaphones and some changes to the carbs and it only added only 9 hp. Hmmmm. I thought I would see larger gains in HP.

What are the before and after numbers?

I see you are in SF, where did you go for the dyno?

It's tough to get real HP gains without major internal engine work and enhancements. The 911S 2.7 from 1974 was rated at 175 min HP. What 2.7 is yours, and what did it run at?
