    Temperature hunting at stop lights

    Just got it swapped out. Did a comparison test. 4 core standard tube - 40° difference between inlet and outlet. 3 core wide tube - 70° difference between inlet and outlet. Used water only on both tests with dual 14" electric 2750 cfm pusher fans. Engine temp 190° at idle, 98° outside air temp...

    Who knows auto insurance? Ins outs loopholes

    CYA = cover your ass And no they paid $47 I got stuck with the rest. Most insurance only covers what a comparable replacement would cost ( Kelly blue book value ) IN YOUR AREA. accessories or upgrades don't count.

    Temperature hunting at stop lights

    I've just recently found out a major difference between brass and aluminum radiators. Brass tubes are more efficient than aluminum. That's why new aluminum has a wider tube design. 2 core wide tube aluminum = 4 core brass. Longer fin contact transfers more heat. Switched my 73 454 to aluminum 4...

    A/C Oil question

    69 should be the big brass stone instead of the plastic tube. 78 or 79 is about the time they started using the plastic orifice tubes. 134 is the reason for the change in design. It needs the smaller valving. Although the the brass is reusable and doesn't break down from heat, it's harder to...

    Worth purchasing 1976 c10 silverado in fair condition for $2500?

    California went by 25 years and older when I lived there. Had a 71 i fought for years with. Needed a timing retard cable to pass. Couldn't find a cable for it let alone the distributor and trans to work with it. Every year I had to go to the ref. And show the paperwork the parts didn't exist...

    vapor lock issues again!!!

    The fuel valve is easy. You can use a vavle from 86 or newer that has a return built in ( TBI has 6 ports vs. 3 for carb. ). The wiring wouldn't change. The valve gets power for tank 1 and loses power for tank 2. As for fuel pumps you could use a relay off your sending unit signal if both tanks...

    Upper Door seal question

    The second door seal is for water. Later years had a steel drip edge over the door to keep rain from seaping in. The seal recreates a lip th channel it around to the sides. Since the top is flat water pools and can wick in, it also prevents dumping it when you open the door. Wind noise is due to...

    Who knows auto insurance? Ins outs loopholes

    I don't know how your state works but Texas laws suck. If the person who caused and at fault for the accident only has state minimum ($30,000 in Texas) that's all insurance will pay regardless of damages or injury. My car was parked and hit totalling it. $60,000 truck gone. They had state...

    Smoke machine advice

    I have the autoline pro. I've used it a few times and like it so far. I like the variable pressure to find large or small leaks. Used the higher pressure for an intake leak on a 5.3 ls. Hairline crack on bottom of plenum only caused problems on cold days. Went through 4 cans of carb cleaner and...

    1987 R10 Prop UJ

    I have a 71 c10 had a similar problem. Pinion straps and pinion got worn out and got loose. Simple fix or experiment was to get a set of morose capture caps. They are for drag racing but enclose the joint from the sides and top. Moroso U-Joint Girdles 85800 4.25 out of 5 stars ( 9 ) Part...

    What type of transmission

    Gm went to the spring tensioner collar in the late 60s. 67 on up all use a spring which weakens over time. To fix it you have to disassemble the whole column. Make sure when you do to keep the shims and arms in order. If the notches are worn weld them up then file to fit the tongue. Gap should...

    Mystery spacer

    I'm guessing this is in a 4x4. The extra washer is an old mechanic trick t keep the filter covered on steep angles or for extra deep pans such as motorhomes. Oversized washers were common at the bolt head to help filter from getting bounced off.

    What is supposed to go here on the HVAC blend box?

    I just went through this on my 73 c30. If you loosen the mounting bolts for the heater/airbox you can adjust it by lifting or rotating it. You'll need a second person to tighten the nuts on the firewall once you get it where you want it.

    700R4 Aftermarket

    The difference between early and late 700r4 is the valve body. Early had a 1 piece valve body which made an easy conversion for nonoverdrive cars ( 1 wire 1 pressure switch ) later 700r4 referred to auxbody used a 2 piece valvebody with the auxiliary valve controlling converter lockup.
