Whoa!!! If I remember correctly your running a late 302 roller cam engine
and you installed the "old" distributor out of the 260 ?? The cast iron
distributor gear on the early distributor will be eaten alive by the steel
cam gear on the roller cam. This will spread fine cast iron wear particles
throughout your new engine in a very short time. If this is your
situation, I recommend that you stop driving, like now, and get either an
'85 Ford 4 bbl (Roller cam with carburation) or an after market
distributor made for the roller cam engine.
The carburetor "stumble' you referred to earlier sounds like the classic
symptom you seek when attempting to optimize your primary jet sizes. This
condition is a lean miss and tells you when the jets are too small to give
a smooth cruse. About jet two sizes above those that create the onset of
this symptom should give a good optimum for normal street operation. The
jets need to be big enough to keep you out of the power valve under normal
freeway cruse conditions, otherwise you will loose substantial gas mileage.
I will try to get some digital shots of my modified S-10 shifter to you
soon. As I said, it was modified to run with the tranny rotated 20 degrees
toward the driver so in your straight up application, it would be pointed
toward the passenger. It could be disassembled, heated, re bent, and
reassembled again.
