    Convert to 350 vortec

    You sure it’s not a replacement block? Gm sells replacement blocks continually since like 2017 for the final revision of engines and that casting is the crate engines iirc

    Doubledingo's 2005 4x4 Tahoe LS

    interesting seeing a denso alternator on your truck The rear doors may have had the lights if those panels are original. if they are swapped your truck may have not been made with them. doors lost them in 03-07 it seems DRL on these are nice in that they dont use your headlights to work, so...

    Convert to 350 vortec

    The blocks of cars were roller, but the trucks still had flat tappet The engines block , drilled for the keepers or whatever, yes. The vortec wont have any provision to drive the push rod, if you have a machined boss you can use a mechanical fuel pump to simply act as a fuel pressure...

    Doubledingo's 2005 4x4 Tahoe LS

    A new 14 volt DRL bulb, P/N 15199562 (trade bulb #4114K), is now available for use whenever a DRL lamp bulb on the above listed vehicles requires replacement. This more robust, higher voltage DRL bulb replaces P/N 1999482 (trade bulb #4157K). These bulbs should be replaced in pairs for customer...

    Unusual radio issue

    hmm. if it wasnt a radio and also dangerous if grounds in the truck became bad, id say switch the ground pull the ability to stay on , but that is risky and would be noise inducing im pretty sure

    Too high Hydrocarbon on emission tests-Help

    yes, good questions, gets to the heart of the problem and offers a solution that also makes a quirky feature lol

    Unusual radio issue

    id recommend a resistor on the wire then, not one that will light a fire of course, but something, the electronics are looking for current and the tiny bit not being soaked up triggers the thingy, so maybe a little resistance would make those instances not happen. it works for LEDs ghost...

    Unusual radio issue

    have you ever done your ignition switch push rod or the switch at all? these trucks wouldnt surprise me if there wasnt a fair amount of ghost voltage in the wiring from miliamp level shorts at things like bulb bases , cracked wires etc. You could run put a small resistor on the wire for power ...

    Unusual radio issue

    I didnt even read this thread again but its funny my suggestion last year was the thing i suggested is possible this year LOL. The radio youre talking about is a aftermarket right, not OEM?

    Too high Hydrocarbon on emission tests-Help

    if i had to guess, it would be because of the high idle cam of a carburetor And a 4 barrel 1406 is a LOT of carburetor for a stock 250 inline 6, and it will probably have some touchy driveability I advise something like a Holly economizer or some other 2 barrel preferably progressive. unless...

    youd get access to the top and back of the engine at the expense of the front

    Too high Hydrocarbon on emission tests-Help

    but youll be down to a 1 barrel, unless you get something aftermarket Id recommend something that lets you install a rochester 2jet but realize the varajet ii is complex but its the most versatile 2 barel that allows you to get the most use out of your 250 its a progressive 2 barrel Another...

    while waiting in line to test, the cat might cool down, running at a high idle might help oops,nvm, awesome!

    Search for a spare 15-inch wheel or two

    yeah that was NOT easy for me back when I did the intake manifold, no matter where i stood it was hard, but i figured out with the plow out i could easily kinda "plank" from the front , with out a board and kinda awkwardly look like i fell in and then just feet at the plow mount under the top...

    Th350 behind 4.8ls

    I now feel the need to ask what kinda things were done to make the th350 compatible here, because the issues you have may Just because the pCM is expecting a transmission signal of some kind and cant get it, so its assuming youre in limp home which means it cant reliably know what youre trying...

    Front brake dust shields

    heres 1978 D44 front shield on the hub, sorry about the snow The only differecne that I know of is that the axles in half ton would have smaller brakes for 15 inch wheels, but i dont know if that means the whole thing is smaller and the rotor is, or if the thickness of the rotor/hub is...

    Front brake dust shields

    i think you need to compare to the knuckles, the reason the old ones are functional both ways and those as you say are not, would make me think the knuckles are some way not able to work both ways
