Engine Blog: First 302 Experience - Minor tuning tweeks NOT MUCH LEFT TO ADJUST!

I've been away from the engine for a while. I installed the body for, I hope, the last time but we will see on that point.
So my friend Mike came over a couple of times this month and we adjusted to things. I had never really precisely done
the basic timing (just close) so that was pretty easy with two people. So it is now at 13.5 or 14 with the spout disconnected. After
that we did a procedure to calibrate the WOT sensor to optimize that computer reading. It was off quite a bit. We have
the baseline at 1.0 and the WOT reading is 4.7. That is about as good as we could do. Also, I put a heaver spring on
the trottle body butterfly and adjusted the idle to about 1000 rpms. I was pleasantly surprised that the engine runs
smoother and I don't kill it nearly as much. I must admit, I am learning how to drive a straight shift again. I believe the
RAM clutch and such made it a little more challenging than your average straight shift car. As of now, I can't figure out
what other things I can do to improve things. I will put some hours on the engine. Right now I must have five miles total
and about an hour of run time. I don't suppose the engine is even broken in such as seating the rings, etc. The DMV
thing happens next week so I will be putting a lot of test trips on it very soon. Another issue is: when I am driving for
these short test runs, I'm concentrating on keeping it between the ditches as it is pretty spirted. I don't want to find out
just how crazy it is until I get more comfortable with it. But it's hard to concentrate on one little issue at this point. It looks like the next logical step is an A/F meter and some version
of an after market tuner (with a heavy dose of education!). Right now, I'm loving my Cobra engine. See you later.
WEK. :cool::cool::cool:
