Re: DynoDay Dissappointment... (Clink69)
I'm planning to disconnect/plug the vacuum line that controls the thermal actuators. An added measure will be to insert screws just below the flaps in the air cleaner to keep the actuators from rotating (blocking the flaps).
Will advise.

Re: DynoDay Dissappointment... (Clink69)
They are on the outside of the air cleaner...
I took the C3 out and what a difference!!! Took it through an 1/8th mile on a lonely stretch of road and it hooked in 1st, positively shifted from 1-2 (used to stagger before catching in 2nd with the 3.06 first gear ratio) and banged into 3rd. The car 'feel's stronger and gets up to 4500rpm between gear changes in no time at all. I really do believe the air cleaner was 'shutting down'.
Now, I gotta buy $75 worth of time on Race Related's dyno to be sure. :smash: :smash: :smash:

The a/f ratio spiked over 13 after I took my foot off of the gas. Prior to that, it hovered around 11.8-12.0. Old a/f hovered between 13.2 and 13.5 right up to 5200rpm.
You should be getting way better HP and TORQUE than what your dyno shows. Keep tweaking and diagnosing until you get it right. My presumably stock 350 with factory '69 style side pipes turned 289FTLB of torque with 203HP. Here's some images of my dyno run sheet:

Re: DynoDay Dissappointment... (TedH)
I found this out a while ago. Someone unplugged the vaccuum source for
the air cleaner.
After testing, I found out why..... (as you know.)
So it seems your thermal sensor on the air cleaner or the vaccuum flap units
are a little bad...
Good luck.
