Default DYNO TIME -- How much $$$ ?

Considering a day on a dyno. This dyno guy has solid reputation so I'm confident about quality of work. And the '68 is set up with exhaust bungs so we're set to do exhaust analysis during the session.

Questions --
1) What will a day at the dyno do for me? The car is running well with current "rough idea" tune-up. Realistically, what sort of power gain can I expect from carb and timing optimization? And does having things optimized buy me anything in terms of engine life?

2) What should I expect to pay for a the dyno session?

Here's my situation:
Recent rebuild of our '68 big block.

Excellent rebuild, and significant investment, including all new internals. Running 9.5 compression and a bit more cam vs stock, not radical, a street/strip grind.

A day at the dyno would be fun, for sure. But frankly my hobby budget is feeling a bit tight right now. (Isn't everyone's?)

Thanks all-

1. well hopefully it will not take an entire day for the guy to tune your car. If it is running pretty good to begin with it should not take too much to get the timing where it needs to be then play with the carb. Depending on how off your current setup is you could see as much as 30-40hp. A good tune will definitely help for engine life especially if your timing is to hot you could burn up a valve or piston.

2. Most Dyno sessions will charge by the hour for tuning and just dyno pulls to get hp......expect $75-100 for 3 pulls and any where from $150-200 per hour for tuning.

If you can spare the time and money-go for it!This is a good opportunity to learn and know what and where your real no BS power is.
The key is to be well prepared with a good running engine and a definite plan for changes in tune with tools and parts.In about 30 minutes you will likely learn what you will in a day or two of pissing around on the street....

with tfi racing, on a new build think of it as money well invested! A rich running engine just fouls plugs, a lean engine will not last long........
