I am at the stage of
designing my exhaust layout for my 20B. what direction would a stock
exhaust manifold exit? I'm guessing that I will have to have one in hand
to see how the clearances are around the engine mount. that may force me to
have one fabricated. any idea on the availability a 20B exhaust manifold?

Re: Bernie Update, Good news& bad, empty weight and injectors
Yep, Tracy
listened to them click and they all sounded good when he was here 2 weeks ago.
I have pulled them and currently thinking of ways to test them off the airplane
at the minute. They are 195500-1350's and if you do have some that I could try,
would appreciate you mailing them to me. I'll be happy to reimburse you the
mailing cost!
I'm sure Tracy also
checked the impedance? Were they high or low (with external
resistors)? The number you have came in two flavors, one was red, low
impedance and came in the 86-87 NA engines. The other was
purple, high impedance, and came in 88 NA engines. I believe I
have two of the 88 high impedance version at the hanger. If that's what
you have, I'll sent them your way, though it will probably be
Monday before I can mail them.
