Almost 300,000 Miles

Gosh, it’s been a while since I checked in here. After chugging around with almost 300,000 miles on my truck and I thought it was a good time to give her some special treats.

I finally had the old Rochester 2-Jet carburetor rebuilt.

I switched up to a 195 degree thermostat (from a 180) even though I removed the air injection reaction system.

And I advanced my timing to around 7-degrees. I have always had it set to specifications of 2 degrees.

Wow! The old 307 purrs like a kitten at idle, but jumps off the line now. No pinging at all at any rpm. The old GMC is running strong and I feel like a kid again, I can’t keep from grabbing second gear! I know this isn't some high performance build story, but for me, this little bit of fine tuning made an awesome improvement. I just had to tell someone.
