    Collapsed Lifters 95 GenV Big Block

    If, IF the studs' threads are OK, why not R&R rocker nuts with same OE "interference" type, but New?

    I need mental help!!! What should I do?

    If it's a keeper, my vote's for swapping in the van's LS --- freshen-up/touch-up that 6.0L LY6 along w/ its 4L80E --- buy the proper ECU/PCM/ harnesses & fuel pump --- Instantly very reliable & 360+ hp.

    Oil Priming on L31 Vortec

    Did you replace the small oil gallery plugs (Right & Left) at front face just behind top timing sprocket? If so, did you replace with same type; OE L31 have a small hole in both R & L plugs ? It matters.

    Oil Priming on L31 Vortec

    I've used a cut-down old dist as a prime tool. But ya don't have to do that --- instead & with Any dist installed, ya can use a $10 cheapo pump-up garden sprayer and pressurize the system while rolling motor thru at least two complete revs

    Had intake leak and now what

    seems Dorman's 615-300 sub-par lower intake for L31 has been discontinued. crazy! 'bout 8 years back, a local yard paid my friends to install an L31 for their customer, it has a slight rattle so it had to be replaced; and my friends got paid once again to R&R motor. First one ran good but...

    Had intake leak and now what

    Yup, that's too stupid for me; Anything more than $200 New ain't on my radar. Big fan of L31 but, thanks all the same.

    Had intake leak and now what

    How & when did you find the first JY manifold was warped? Was it discovered only after you had installed it and it failed?

    Building a stroker motor

    If I had unlimited funds I probably wouldn't be screwing around w/ $10K pickups. That said, if ya want truly BIG inch sbc, our kiwi friends were doing a 600" sbc for jetsprint race boats. JMO, there's little more ballsy than jetsprinting except Isle of Man TT mo'cycle races (rather lethal, June...

    Building a stroker motor

    suggestion: if ya go more than 3.8" --- suggest go to a bigger bore like OE or aftermarket "400" piece. They breathe so much better with a larger bore; bigger bore helps unshroud the valves, it matters. No doubt the shrouding effect can only be increased by a 4" stroke in a 350 block. Of course...

    1993 Yukon crate motor hydraulic roller lifter cleaning and adjustment journey - (Solved)

    Seems many of that style VC are cast magnesium and seems all have little to no room for any roller rockers.

    starter bendix gremlin

    next time: upgrade that old heavy amp-hog 10MT starter to a modern PG260 Permanent Magnet Gear Reduction starter for a newer truck (e.g. 1998). Integral to any such upgrade is to get the newer bolts as well; the old bolts will fit but you'll never get em to stay tightened in a new-style starter...

    Heads and cam?

    since ya have little money in current JY motor, suggest start a new build with another JY motor: this time choose a roller block or, even better, a vortec L31 motor (eighth character in donor VIN is an "R") * ya really NEED to pull the lower end apart to clean out any metal from failed...

    Ball Joints Brands

    I remember "Precision" brand U-joints (alternative to Dana-Spicer or MOOG) Dunno if Precision U-joints still marketed; nor who any parent may be. I probably still have an older Precision U-joint catalog somewhere.

    Door card insert Material change

    I grew up w/ family JY in SE USA --- no spring chicken --- all i ever heard/used "door panel" --- until some UK-based used car flipper shows turned up on cable. Dunno, seems David Vizard calling NC home these days; but he's a motor pro not bodywork.

    Vortec intake manifold pitting

    ^^^this^^^ And instead of the "bad" biscuit roloc discs, years ago I switched to 3m "bristle discs" --- Far less aggressive. Yes, they cost more but results are worth it. Works for me, YMMV https://www.3m.com/3M/en_US/p/d/b40064937/...

    Vortec intake manifold pitting

    if what you're doing doesn't suit ya--- Kevin Blanks Performance (434) 374-2188 6909 Highway Fifty Eight Clarksville, VA 23927 * not exactly Eastern NC but not so far either. For real race car blocks' lifter bore bushings, I've driven it from Eastern SC. pretty much about 80 miles Due North of...

    Had intake leak and now what

    Jeez Louise ! did a brief search for a New replacement LOWER intake manifold for L31 Vortec 5.7L V8 --- seems neither GM, Dorman et al offer them now. that leaves little else but: 1) DIY fixing what you have via weld, epoxy, flat-file etc or 2) finding a good used one (fleabay etc choices are...

    Best Intake gaskets

    I prefer the rubber-steel Vortec L30/L31 combo. In addition to Fel-Pro, Mahle also has a good rubber-steel intake gasket. On a Vortec 4.3L V6, I've been pleased with rubber-Aluminum gasket. The rubber was a light mint green color silicone on an Aluminum carrier. Sorry, don't recall brand...

    Budget 350 build combo

    JMO begin with a JY core L31 Vortec 350 that's chosen (in part) because it has no tell-tale signs of overheating; build that core, thereby supporting your local auto machine shop. If ya don't support em, they won't be there when ya need one. food for thought: with TWO glaring exceptions, the...

    1995 GMC 1500 Manual Transmission- Do I have a Transmission Cooler on the Radiator?

    :waytogo: maybe that'll help lower price for rad? Although, you probably could drop-in a rad with EOC/TOC if that's only version available.
