    Crank relearn and cam retard offset question

    I'd pursue the tune, too. IDK how or why you'd need to do a Crank relearn. The crank sensor says, "Now, now, now, now, now..." and that's it. It's mechanically keyed to the crank in one, fixed position that TELLS the ECM where the crank is. I don't think I'd want to be "relearning" the ECM...

    Where to buy 94 5.7 TBI Intake Manifold studs or studded bolts?

    ^That^, or a nut and bolt house. They may not have 'em on the shelf, but they can get 'em. Fastenal Bowman Grainger Lawson etc. OR a local nut/bolt house.

    Unhooked parts in my engine bay.

    You simply push "in" on the white plastic retainers/clips. If you look at the connectors, the white clips are open on one side of the connector, and closed/connected on the other side. Push the closed/connected side of the white retainer/clip, in and pull the connector off the nipple. Easy.

    Really wish ppl would stop bringing me trucks with hydraulic fluid in trans

    Actually, it DOES apply. The assertion that the OP was really making, is that none of us are lube engineers (or engine, engineers), yet you got every Tom, Dick and Harry, telling themselves stories and rationalizing all manners of arbitrary concoctions as being a "solution" for their particular...

    Am I underpowered?

    I agree with the others who said that you need more gear. Also, if you really want to know if you're engine is making expected power levels, MEASURE IT. And I don't mean by using the famous "Peel-O-Meter". Put it on a chassis dyno or down the 1/4 mile to get a trap speed, and calc your...

    Not really. Anyone can cherry pick some, single example to show me "how wrong I am!". But my feet are both fine. My "generallizations" are generally true. It's good for the people who don't know, to know. For the rest? If you dig 30wt in your oil-hole? Use the wee out of it. :waytogo:

    305 Vortec Cam

    OP should state his budget. We don't know what it is. I think the cam is a good start, since the stock cam is so small; it's low hanging fruit....especially if the OP is going to change it himself.

    305 Vortec Cam

    ^I agree^...you CAN do, just a cam. You do not NEED, screw in studs, especially for mild cam upgrades, which it seems the OP is talking about Finally, you do not NEED to measure and change push rods with a mild cam upgrade....anymore than you could and "should" measure for proper push rod length...

    1998 GMC k1500 engine swap 5.7 l

    They're compatible; same dimensions/bolts in. Wait to find a 5.7. The 5.0 is gutless, IMO.

    305 Vortec Cam

    Used cams are a viable option since: *It's a roller cam *It's a low RPM motor (even after a cam) *Even "a cam" -that meets these criteria, is still going to be quite conservative and easy on valve train. Keeping budgets in mind, I'd look for take-out, stock/factory roller cams from anything...

    This is ODD (305 Vortec issue)

    There is a dimple in the gear just below, and about the same diameter as the roll pin. That is used to position the distributor shaft, relative to the housing, before installing the distributor. This is only required on the '96-'99 Vortec. Since you said flat tappet, the TBI doesn't require...

    Having trouble with a no-start 98 5.7 vortec

    I agree, 7 years of sitting+ good fuel pressure, + runs on ether = most likely: stuck poppets in the spider. And yes, it's possible to fire the injectors w/the plenum lid off. Have a fire extinguisher handy. I've had good results tapping on the injector/poppets w/a light device to give it a...

    This is ODD (305 Vortec issue)

    I doubt that the cam teeth are bad. We'll see. For now? Runs great. Smooth as silk, no CEL. No power either (same as ever), but it "Gets on down the road" just fine, which is about all one can expect from the 'ol "Grandpa Truck". :rofl:
