    7.4L Vortec Distributor Suggestions?

    LOUD rattle when engine starts

    You soooooooo! have an internal problem.. First just to be sure take the belt off, fire it up see if noise is still there ... that will rule out any accessories.. It really sounds like a pushrod banging away though. Take the valve covers of to see if something is broken or has major...

    Have to bump throttle to keep running. Won't run at any steady RPM.

    For fuel pressure an easy way is to make a t -type fitting at the fuel filter. It's much easier than trying to hook up behind the throttle body. The TBI doesn't have a schrader valve. Solus pro would work if you have the obd 1 attatchments . My prospects from what you describe I would lead to...

    CEL Codes, and a misfire.

    OK ,now we know more. Yes, with popping through the exhaust you have a timing issue for sure. However.... did you remove the heads or rockers? If you did your lash my not be right on some of them and that can cause some of the symptoms you describe.. Usually for the 1345 code crank sensor...

    CEL Codes, and a misfire.

    You should reread what you wrote because that is what it implies.. You didn't define it.. and where is the whole knock thing coming from?? Since when is misfiring a knock? A broken mount is not going to bang around and KNOCK during idle a bunch of times and at a steady acceleration.. Only...

    Fuel delivery issue 1997 k2500 7.4 vortec - random not starting

    I'm with him.. I think you have a wiring/ground problem possibly causing the pump failure..

    454 engine swap

    Not to mention HP and torque.. I would do all I could to maintain the Gen6 . All that effort just to go backwards in the end you will probably be disappointed .

    CEL Codes, and a misfire.

    Ok I've been working on cars for 30 years. You are going to have to explain to me how a motor mount is going to cause these codes or any on a 7.4 ..

    CEL Codes, and a misfire.

    You really are going to need some type of scanner to get some sensor values. Even most of the cheap ones show data.. That's what leads to figuring out what's going on.. The data is important. DO you actually have a misfire(like codes?)or just feels like it's missing? Scanner data would...

    Chasing P0302

    I would agree with that.. That's getting low. stock is around 150ish psi with about -20 psi for max tolerance.. according to my service manual.. Check it again and if the same, proceed with a leak down test before you throw any parts at it..

    p0174 454 vortec

    Usually with something like Besides checking misfires and the graph. I like to double check all of the ignition parts. Loose plug wire, loose plug backing out, wires rubbing thru ,wires snug on cap, cap solid on it's base . You would be suprised at how that one can get you.. Then kind of...

    It runs...but still an issue

    Yep, get it HOT!! Will take some time .. Unless you drove around a long time before you fixed it. If the cats were exposed to coolant for a long time (like days of driving around) then they may be compromised.. Go hit the highway for a while..
