Almost 300,000 Miles - The 1947 - Present Chevrolet & GMC Truck Message Board Network

SacramentoJoe · 11-13-2009, 07:24 PM

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.

Still running like a dream right Joe?

Glad to see the old girl still on the road.'

Here's to the next 300k!

all I can say is DAM!! I want to know what your oils and services are...those are better than diesal #'s

70 shorty · 11-13-2009, 08:18 PM

Awesome. The truck looks like it's in great shape.

arm51 · 11-13-2009, 11:29 PM

wow thats amazing how long has that took to rack up all those miles

vasquezmrysvll · 11-14-2009, 03:38 AM

iv seen this truck before. nice

**special-K** · 11-14-2009, 05:58 AM

Sacto Joe,it`s been awhile and your truck hasn`t aged a day.I can`t remember,is that the original motor?I don`t believe I`ve never seen a 307 with the old-style intake before.

I just have one other question...Does you daughter like the truck?

I started keeping maintenance records back is 1986 when I had the motor rebuilt. It had 163,000 back then. I have changed the oil every 4k-5K and replaced things as they broke. I have gone through a few transmissions, radiators, etc. I used to drive around 12,000 miles/year back then. Nowdays, its only around 1000 per year. I was also going to replace the points and condensor since my records show the last time was 9000 miles ago, back in 2000! But the dwell was spot-on, so I will wait a few more years.

All three of my kids love my truck. My son thought the engine had died at the stop sign because it was idling so smooth.

that looks nice for 300,000 miles !!

dan42 · 11-14-2009, 12:12 PM

It sounds like that motor is balanced very nicely. Good to see it's lasted so long.

SacramentoJoe · 11-16-2009, 05:38 PM

The odometer reads 99,990 today. Now, I don't want to drive it more than 9 miles. I just sit in the seat and stare at the numbers.

69GMCLonghorn · 11-16-2009, 07:44 PM

Hey, when it comes time for new point, swap 'em out with a Pertronix Ignitor. As amazed as you are with your truck now, you'll probably be that much more amazed with this quick addition! The cold starts are awesome and just all around performance improves.

Great truck, story, kids, etc... Good luck to ya! Keep it going!

SacramentoJoe · 11-22-2009, 05:48 PM

Well, I clicked the odometer over today. I was driving to my dad's house so my boys could mow his lawn and rake the leaves. We all celebrated as it turned over. My mom looked at the odometer and said she remembered it had 8 miles on it when they bought it new in December 1968.

My 14-year-old son can push in the clutch now so, soon, he will have learn to drive her.

I'm gonna go run some errands. I love to drive my truck hard, like I always did when I was a kid. That way if something breaks, I get to buy something new for it.

**Palf70Step** · 11-22-2009, 07:24 PM

Sweet ride. I have always like the look of your GMC. Keep er rollin!!!

SacramentoJoe · 11-23-2009, 01:27 AM

So I went out to run my errands and learned that my son had jammed the gears, the truck wouldn't move. I had to get under the hood and get the collar and the shifters aligned on the steering column. Its good to see that the security system is still working! You gotta have finesse to drive this machine.

unclewatts · 11-23-2009, 01:51 AM

Gee Whiz! you make me feel like my truck is brand new. I only got 152,000 on it.

82swampthing · 11-23-2009, 02:12 AM

can't beat those 307 engines .

MrBlue · 11-23-2009, 02:39 PM

Just wait until the kids start driving, and maybe they can add a post is several years stating that the truck is at 500,000-miles!
Good Luck

If your son has trouble learning how to finesse his way through the 3sd gears try this adjustment from FAQ.

Unless you want to use this as a reason no one else can drive your truck

. Do yourself a favor and get couple new shift tube control arm grommets (1.29ea from classic parts). Worked wonders for me.
