It seems installing a 200r4 would be a good option in the future, but a higher priority right now is a paint job

.
I just set my timing by following the tutorial I mentioned above, and my new "curb idle spec" is 18! That's a lot more than 7... I will road test it soon, but I look forward to seeing what kind of mileage difference I will get from that adjustment.

I might still experiment with the 283 heads in the later summer, but for now, are there any other enhancements/upgrades that I can use on my engine to get more performance/economy? panhandler62 mentions using special spark plugs, and '72customdeluxe mentions an 02 sensor kit, is that really worth the money for tuning the engine better?
