Possibly...

As far as exhaust, exhaust leaks can reduce performance too.

That sounds to me like symptoms of having the timing too advanced.   Try
retarding the timing and/or running a higher grade of fuel to see if
anything changes.

Good luck.  I highly recommend checking the timing.  Maybe retard it a
little by ear and see what happens driving if a timing light doesn't show
anything odd.

As far as the dash pad, I forwarded your response and asked him.  We'll see
if he has one you can use.

Thanks for the RHD p/s stuff.   I didn't really have a reason to pay as much
attention at the time and had completely forgotten that post.  All I
remembered was a corvette box that required installing the box where it
poked out of the body.
