    1987 V3500 Engine update

    Owned 2 C30 cab/chassis 1988 and 1989 1-ton DRW 454. Both were TBI. Do remember working on customer dual air pump carbed 454's during that time, unsure what year they were. Horrible to work on, guessing 87.

    Bleeding rear brakes on 1978 C30 dually

    Most of our trucks were cab and chassis. And yes, very tight. When replacing shoes, always check the bleeder before installing anything. Stuck or clogged bleeder usually means removing the wheel cylinder or at the very least unbolting backing plate for access. Plate can be pulled away from...

    Bleeding rear brakes on 1978 C30 dually

    These are what I used. Bleeder should be 5/16 or 8 mm. Sometimes a long combination will work. If tight will need a box end wrench. top Matco SPW100 3/8 5/16 bottom Snap on B1458C 1/4 3/8

    Can’t find a heater core for my c20 suburban…

    Could be parts consolidation? Even on much later vehicles heater cores can be slightly different than OEM.

    1979 c20 charcoal canister

    Use number on top for internet search. Could also try used and with a vacuum pump check proper operation. Finding new ones may be difficult. I got lucky found a new one like you have near the radiator but that was a year ago.

    350 small block

    All carbs with an open bowl vent, fuel will evaporate with time. Overnight no, a week or 2 yes. Ethanol and higher temperatures it will be more problematic. I haven't installed an Edelbrock carb recently but in the past most needed jetting and adjusting of some sort. They are generic, not...

    350 small block

    Above + linkage has adjustments. Accelerator pump is in the front right corner. To check operation, engine off, open choke plate, look down venturis and open throttle. Should produce a reasonably strong squirt of fuel. Ethanol fuel is not your friend.

    Dynamic compression

    Cam design can relieve compression. 8.8 should be fine. A well-designed cooling system will help.

    Filling in seams

    One of mine has been painted so many times the seam on the B pillar is almost non-existent. Guessing 5-6, stripped 3. I like the look.

    Collapsed upper radiator hose

    Could you explain further. Depending on configuration, isn't it possible air could still trapped in the system? The return hose goes back to the water pump in many cases. The air is now in the block and could uncover the stat? Systems that have returns back to the radiator right tank, agree.

    Collapsed upper radiator hose

    Had Tylenol in the toolbox will those work? lol Anyway use whatever method is easiest to vent the air. There will almost always be a little residual, usually need to add coolant after first heat cycle or 2.

    Collapsed upper radiator hose

    When filling an engine after repair good idea to leave thermostat housing off and fill until coolant is present. Then install stat before starting. Can do the same with a heater hose if located high on the engine. By the time a thermostat opens from steam engine is overheated.

    Power Steering Squeel

    What I ran into [hindsight should have been quite obvious] was the water pump pully had 2 groves the same diameter, crank pully 2 groves of different diameters. Was off just enough that belt slipped without noise. When more drag was placed it was enough to create noise being as the belt was...

    Power Steering Squeel

    Respectfully disagree, had that problem on one of my trucks. Drove me nuts until I figured it out. Water pump pully diameters were not matched to the crank pully. One belt had to always slip. Didn't manifest itself until the belt was put under a higher load, squealed. It's actually quite easy...

    Best tires

    Used to be a studded tire fan until I tried a set of Blizzaks for the daily driver. Whatever the tread is made out of works. Michelin has another ice tire but haven't tried those. Only use that car about 5 k a year so I leave them on year round. Have been getting 25 k miles out of a set. They...

    Best tires

    I was a tech at a shop that sold tires. Hankook and BFG were the best tire for the money, casings were round and didn't need as much weight as some other brands. Have a set of each on 2 SB. Both are quiet and work decent in all but extreme conditions. Will say this however, neither stop very...

    Idle timing

    Vacuum advance units can vary from about 10 - 30 degrees. Centrifugal weights, and springs can be much different as well. Usually, heavier [higher GVW] the truck lower total advance is. Although total advance may have been conservative back in the emissions days have to remember octane today...

    Oil pressure sender switch and coolant sender what type of thread sealant to use since your not supposed to use Teflon so it can ground correctly

    Liquid teflon never hurts if used in the correct places and not over applied. One thing to point out, in an ideal world those fittings may be fine without additional sealers. Problem is we are dealing with mostly used parts and not clean threads. I have been burned too many times not to add a...

    Dual Tanks Fuel switch delete

    Done on larger [higher] over the road trucks. Our company used low profile trucks. Factory would not install dual tanks like that because the possibility of damage and fuel spill.

    Finding smog pump 1985 Chevy K20

    Using early manifolds lower ac bracket is a problem. This truck has those on it when I bought it. They can be made to work but requires modifications. Using an early 6 bolt manifold on the right side requires an adapter plate for the 7-bolt head. Mine always leaked, poor design. You will also...

    HEI module dwell time.

    Those Sun machines were state of the art and expensive. Cost 8k in the late 70's. An 1115 came up for sale close to me cheap, bought it. Needed an infrared board and a lead. They take up a lot of real estate in the garage but worth it if working on points vehicles and carburetors.

    HEI module dwell time.

    Basically same as valve float. Inability to control opening and closing. Solving point float sounds easy, increase closing spring tension. Problem with that is increased rubbing block wear and wear to advance pin, especially on Fords. A friend had a Sun distributor machine. Was educational...
