1979 Chevrolet C70 Conversion to OEM Air Conditioning

Yes, it does very well. It likes 65 MPH best but if I hold it to the floor it will do 69 to 71 MPH. Keep looking they are out there just hard to find.

Texas Early Day Tractor and Engine Association show.

Re: 1979 Chevrolet C70 Conversion to OEM Air Conditioning

Need help, the bow tie emblem fell off my grill and was lost on the highway. I purchased a new one from AMD P/N 999-4073-13 that appeared to be the same, however it was much smaller (pickup grill size). Anyone know where to purchase a new one?

I have one somewhere around here that could be that size. Post some measurements.

I apologize for the delay. The one I have will not work.

I could not find the larger bowtie sticker anywhere. All that were available were the size for pickups. My daughter (-in-law) Kaylyn did a beautiful job of creating one for me. I can't wait to get it installed. I will post another picture once it is on the grill.

Time for a update. We have driven this truck almost 40,000 miles. The drive train has been flawless except for the Air Conditioning. I am on my 4th A/C compressor. First Compressor locked up forcing me to flush the system and replace the dryer and evaporator. The second one developed a bad Freon leak, the third had the clutch start slipping. The A/C works great, just wished GM had used a different compressor in this era.

I hauled a tractor and other equipment up to a show in Southwest Missouri. I noticed that the engine started to miss and smoke at idle. Once off idle it was clean and smooth running like normal. I decided the rack and valves needed to be adjusted. When I got home, I removed the valve cover and adjusted the valve clearance. Overall everything was real close. The rack was perfect and needed no adjustment. Once this was completed I still had the miss and smoke.

I did another 2,700 mile trip to Northern Indiana. The engine ran find above idle and did not use or leak oil. We continued to have the miss and smoke only at idle. I am thinking I have a broken piston top, or failed Top compression ring. When I get some time and room in the shop I will remove the head to see what the problem is.
