    Crate engine swap advise please?

    The Summit one MO pointed to looks OK too. http://www.summitracing.com/parts/sum-850001r/overview/

    Crate engine swap advise please?

    This one looks right. Has the adjustable vacuum can. Just dial it in to 7.5 crankshaft (15 camshaft) degrees using a timing light. The instructions say to hook it to ported vacuum, which is nonsense. Connect it to manifold vacuum, the driver's side port of the Edelbrock...

    Crate engine swap advise please?

    Oh, and agreed with MO. Get a new stock HEI distributor, with standard curves. You got so much custom and mish-mosh of parts on that thing, no telling what is going on. The stock HEI distributor is not a bad piece, actually. We were overjoyed when GM brought that thing out. Made life much...

    Crate engine swap advise please?

    OK, I read back over the whole thing. One big question mark is the cam. We don't know what it is. For getting off the post, you need torque down low. So one thing to think about is getting a cam kit -- cam, lifters, springs -- and going with either the 12-300-4 or the 12-230-2, for example...

    Uh, roger that. :Insane:

    Crate engine swap advise please?

    That sounds lean on cruise and rich in the power circuit to me. If you take pi*r-squared for the jet and subtract pi*r-squared for the rod to get area of the opening, you are 0.0063 square inches on cruise and 0.0116 square inches on the power circuit. I would think numbers closer to 0.0080...

    Crate engine swap advise please?

    This all sounds OK to me. I would run R45TS at .045", but if you are not getting oil fouling that's probably OK. The MSD stuff I don't know about.

    Crate engine swap advise please?

    Wow. Been busy, just catching up. Yup, with low vacuum you should use lower step-up springs. The general rule is that the step-up springs should be half your idle vacuum. So if you have 18" of vacuum at idle, like I do, you use the 8" springs and stretch them a quarter-inch to get them to be...

    Engine stalling issue

    First thing on the Edelbrock is to pull the air cleaner, then loosen the step-up piston covers and swing them out of the way. Pull the step-up pistons out, wipe off the pistons and the rods, use Qtips with WD-40 or carb cleaner to clean out the step-up cylinders. Reassemble. Second thing is...

    82 K10 Gas Tank Replacement

    LMC shows only one part number for the filler hose and vent hose, regardless of whether it is the 16- or 20-gallon tank, but looking at pics of the two tanks, I think you may be right. It sure looks like the filler hose fitting on the tank will end up in a different spot.

    82 K10 Gas Tank Replacement

    And replace all the rubber hoses and clamps back there while you are into it. No difference in the filler hoses, fuel lines, senders, mounting straps or anything else between the 16 and 20 gallon tanks. Same-same. The tank is a bit longer is all.

    New Engine Coolant Leak, Hi Temp.

    Change the two gaskets to the block when you change out the water pump. It may come with them. Actually, water pump and radiator is good news. Like DoubleDingo said, the (copper) radiator can be soldered for cheap, and water pumps are cheap, and both are easy to get in and out. Really...

    Synthetic oil after break in

    You will get better lubrication and less wear with synthetic oil. I use Mobil1 10W30. If you run synthetic oil in an older engine, you will find out how much better it is at getting into every little nook and cranny of the engine, because if yo uhave a leak, synth will find it! I also run...

    Really hot after shut off?

    Understood. We are both describing the same reality, which we both understand. I just phrased it a little differently, in the way I think about it. I thought an additional explanation might help the OP because he indicated he couldn't understand why it would happen.

    Really hot after shut off?

    The core of the engine (pistons, bores) is hot when running, and that heat is conducting away through the water jacket, which is being circulated through the radiator. So in the steady state while running, the engine core is much hotter than the water jacket. When you shut the engine off, that...

    best way to improve fuel economy

    No, I agree, a new properly tuned Qjet will get a little better mileage than a properly tuned Edelbrock. My recommendation is to talk to Sean Murphy over at SMI carburetors. That'll set him back 400, and maybe perform best with a new intake manifold, depending on what he has on their now...

    best way to improve fuel economy

    Carb to TBI will help, and no it isn't worth it, dollarwise. Your Edelbrock is running rich as a cob. They're setup that way right out of the box so you don't lean-kill the engine if you don't bother to tune it, which most people don't. I have 350/TH350, 31" BFGs (not known for gas mileage)...

    Cam

    Again, a high-rise manifold is intended for high rpm horsepower, and will reduce low-end torque. Just go with the 2701 like MadOgre says. firebane: 12-300-4 is what I have, as you know. Maximum torque at lowest rpm and stock lift for long-term reliability of the drivetrain. I love it. I did...

    Cam

    Yup. A loping idle means the engine isn't set up to run at low rpm, but at high rpm. That's a great setup for a track vehicle, but not for a street vehicle, especially a truck. Probably the best all around cam for a street vehicle in the low-compression 350s is the Comp Cams 12-230-2. Do not...

    Coolant Temp Sensor Question

    OK, that's what I thought. I didn't want the OP to think that having the cap off during the swap was what you meant. We're good.

    Coolant Temp Sensor Question

    Do NOT replace the sensor with the cap off! The coolant will run out like crazy! Instead of a small glug-glug-glug, it will pour out. Once the sensor has been replaced, idle the engine for a bit with the cap off to help cycle the air out. MO, I think that's what you meant, but I want to...

    Look at what I scored! :)

    These guys have a lot of stuff on CD. http://www.detroitironis.com/General_Motors_CD_s.html I got the 73-78 parts manual. They are pdfs. Getting hard to find, though.

    Coolant Temp Sensor Question

    Yup, that's how I did it. 1) engine off, truck cold, pressure relieved by opening the cap, then put the cap back on and seal it so no air can get in the other end. that's what slows down the coolant from leaking out. 2) put liquid teflon pipe sealer on the threads of the new sensor. you...
