    Power Brake pedal

    My 82 C10 has the original brake pedal for manual trans/manual brakes. The truck now has an auto trans and will soon have power brakes, so I would like to install a wider power brake pedal if I can find one. A couple of questions: Does the power brake pedal sit closer to the floor than the...

    Brothers cup holder/arm rest

    There's also this less expensive one from LMC, but with no information about cup holder size or how to mount it. My concern is it might not a hold larger cup like the one from Brothers. https://www.lmctruck.com/1973-87-chevy-gmc/deluxe-console

    Has anybody here tried one of these from Brothers? https://www.brotherstrucks.com/1947-87-CHEVY_GMC-TRUCK-CUSTOM-CENTER-CONSOLE_CUPHOLDER-BLACK/productinfo/CCC0100/

    PSA concerning ICT Billet brackets for sbc

    For anyone fighting imported billet brackets, here's a made-in-USA option. Not cheap, but every one I've used has worked perfectly. http://www.alangrovecomponents.com/

    I could choke a GM engineer!

    My 15 year old granddaughter could do that job! I have found that the better parts stores usually have one employee per shift who has some experience working on cars, or at least knows one part from another. There's an O'Reilly Auto Parts in Allen, TX that used to have woman manager who must...

    Thoughts on running 10 year old tires?

    There are several pictures on the Internet of old tires with the tread separated from the sidewall, or where the sidewall itself simply cracked all the way through. And sometimes that happens with the car just sitting in the garage! Doesn't matter how much tread the tire has, or how many miles...

    I could choke a GM engineer!

    Yep, that's why they use pot metal.

    I could choke a GM engineer!

    Or Lexus. On early LS V-8 engines the starter was under the intake manifold. Heck, we're at the point on many cars where it takes 30 minutes to change the engine air filter. And forget about cabin filters unless you're a contortionist with small hands.

    voltage at idle with and without accessories

    Your new voltages are just fine. 14.2 with no load is ideal, but it's not always gonna happen with older connectors. It also depends on the voltage at the point where the alternator "sense" wire is connected. Voltage at that point is what the regulator uses to control alternator output...

    Upgrading Alternator, Can I Run A Second Wire From Alternator To Battery?

    2 gauge seems to be a bit of overkill. American Autowire uses 6 gauge wire and 175 amp mega-fuses in their Alternator and Main Power Connection kit. https://www.americanautowire.com/media/productattachments/files/downloads/92972153%20510476%20IN%200.1.pdf

    Combination valve rebuild kit?

    Unfortunately, I suspect most of the aftermarket valves are made overseas by the lowest bidders, and who knows where the "knee" is in the pressure chart? (Where rear pressure rate-of-increase starts dropping compared to fronts.) Car requirements are significantly different than pickup trucks...

    Combination valve rebuild kit?

    Thanks. I'm getting ready to convert to power, so thought I'd check out the 38-year old valve while I have everything apart. There are no obvious problems with my brakes other than they're manual and take a strong right leg! But brake fluid was pretty nasty when I went through the brakes a...

    Combination valve rebuild kit?

    Looking for a kit to rebuild an 82 C10 combination valve. Can't find anything on the Internet. Would rather not buy a one-size-fits all valve.

    In search of opinions on gear change.

    Actually, all of the ratios would affect comfort level (engine noise) and fuel mileage. That said, 3.73 has always been recognized as the ideal ratio for a 4 speed auto with .70 OD. Of course that's typically in a car or light truck with 27"-29" tires. If you absolutely must change, no way...

    Locating odd sized bolts

    Try these guys. https://www.boltdepot.com/Hex_bolts.aspx Or just cut down the 4" bolt and grind a 45 degree angle around the diameter of the cut so it looks somewhat like the end of an uncut bolt. BTW, unless this is a metric bolt, if the thread count 18 per inch then you have a 5/16"-18 bolt.

    1986 C10- Is it reliable enough for a daily driver?

    Yeah, and it's always the carb that's at fault. If it's a Holley, someone will say, "Replace that piece of junk with an Edelbrock," and vice versa. North Texas isn't exactly like the upper Midwest in the winter, but I've never had issues starting my old cars or trucks in sub-freezing weather...

    1986 C10- Is it reliable enough for a daily driver?

    Being an an*l gearhead, I personally wouldn't trust anyone else's mods on an old truck to be done right. I've just seen too many mods with good parts done badly. Also, I can tell you very few people ever get 100% of their "investments" back on old cars and trucks. Many times $12K invested...

    Carb upgrade for 250 I6 in a C50

    Don't forget to optimize ignition timing and limit exhaust restrictions, such as a muffler that necks down from, let's say, a 2-1/4" pipe to 1.75" internally. According to David Vizard, a good bang for the buck is a performance muffler that's one size bigger than the exhaust pipe, using...

    Rearend gear ratios 1980-1987 most common

    My 82 C10 had a 250 six with 3-speed manual and 2.73 axle. Not at all suitable with the 250 six, but works well behind a 350/TH350 that occasionally sees 65-70 mph freeway speeds. My 81 C10 had a 305 with TH350C and 2.56 axle. What a slug that thing was in 4th gear with the T/C locked-up! I...

    Keep Frying HEI Coils PLEASE HELP!

    Alternator output voltage is regulated at around 14.2 volts. However, with the path the current must take to get to the coil (bulkhead connector, ignition switch, bulkhead connector again), you might find anywhere from 12.0-13.5 volts at the coil. I've seen less than 11 volts on old cars with...

    Keep Frying HEI Coils PLEASE HELP!

    Very good idea. The MSD Streetfire is light years better than the low-end cheapies. Also, a GM 93440806 doesn't cost too much and works well. It probably has a bit too much vacuum advance, but that can be modified. in 25+ years I have used both of these as well as Accel and stock...

    Best tire on a budget

    Then you don't a 60-or 65-series tire, or anything wider than 235. I assume your speedo reads slow with those short tires you have now. Taller tires will fix that problem, but you've got to do the math, or change speedo gears. Even a 205/75 would be 15% taller than your current tires. But...

    Best tire on a budget

    Rim width is key. I wouldn't want anything wider than 225 (approx 8.8") on a 7" rim. And make sure you understand the height difference between 75, 70, 65 series tires. For example 195/75 will be the same width but 1.5" taller than your 195/65. Your tires are only 25" tall. Way too short...

    Rear End Rebuild?

    Looks like you got what you paid for. :) I don't know what else to suggest unless you can find a complete rear axle somewhere. I think just about anything from a 73-87 C10 should fit.

    Rear End Rebuild?

    My only experience with a shop doing diff work is when a buddy of mine had his 77 Nova's gears replaced. In this case it was an 8.5" 10-bolt with 2.56 gears that he wanted to replace with 3.42 gears. He actually interviewed a few shops and found a guy who really knew what he was talking...
