    5.7L Cold Air Intakes?

    I know this post is extremely old but I'm pondering the same question myself. I have a 4in cowl hood on my 97 for clearance issues with the intake spacer and 80mm big bore throttle body on a built engine with unfortunately OEM style mpi injection set up, would love to obtain a marine intake fuel...

    AC Delco 41-993 spark plug issues

    Bad thing is the tube is bent so far over that it melted the MSD plug wire and then it cracked causing it to arc on the header. if they weren't ceramic coated I'd give them a good hammer tap for space.

    AC Delco 41-993 spark plug issues

    Has anyone had issues apart from the one post of no start on new plugs? It's a couple years old now. So I put new engine in a year ago and fast forward 12,000miles or 18months, and I'm fixing to have to install a new set of plugs wires and distributor cap. Mainly plugs, but here's the kicker...

    14 bolt swap question

    I read through this and I know it's an old post but maybe this will help someone else. Yes they can have LSD'S in the K2500/K1500 9.5 14bolts, and just to clarify yes it's the wider 4x4 axle. I'm installing one from a 1998 k2500. Also be aware that it's not just a simple 8 lug shaft to 6lug...

    1500 heavy half 14 bolt Qs:

    I read through this and I know it's an old post but maybe this will help someone else. Yes they can have LSD'S in the K2500/K1500 9.5 14bolts, and just to clarify yes it's the wider 4x4 axle. I'm installing one from a 1998 k2500 that had an OEM LSD instead of the Govlock posi. Also be aware that...

    Did I totally bung up my swap? (97, 1500, 4l60e, 1 vs. 2 piece)

    Based on my experience having a 97, built in 96 with a 1piece transmission, you have to have a 97 1piece to bolt and plug up exactly without modification based on mechanics and transmission shops/ builders. However based on so called professional mechanics lately I don't trust them, not all, but...

    PRNDL switch

    The transmission. I would have still left the black box PCM in and then it would still work the transmission, but without the TPS sensor the 4l60e wouldn't work correctly, same way 700r4 won't work with out the detent cable or a th350 or th400 without a vacuum line. I put a carburetor on my...

    PRNDL switch

    I finally sent them a picture showing it called both and asked how they were adjusting it the other week if I didn't have one in the truck. Otherwise I'd have a mess of wires bypassing it. I've run into some crazy stuff here lately. Next time I'm putting a carburetor with TPS sensor and saying...

    PRNDL switch

    I don't mean to sound stupid, but can someone tell me what a prndl switch is verses the 4l60e neutral safety switch. Pretty sure it's the same thing but apparently not according to what I'm being told now by the people who tuned my truck. If anyone wants to hear some crazy stuff private message...

    High idling in gear and taking long time to idle down at a complete stop

    It was definitely a vacuum leak. Did a smoke test and found it. Then I replaced the upper plenum from where they messed it up when installing the engine. I put my old one back on that was new in November on my old engine. https://photos.app.goo.gl/CanpoZzDTDxaWLR78

    High idling in gear and taking long time to idle down at a complete stop

    Replaced upper plenum, problem solved. No more leaks as can see in video below. https://photos.app.goo.gl/EftV347qtb37PiEY7 One other thing I might add, everything is brand new and been replaced once, twice and some 3 times since installing the new engine in February. The only thing I've not...

    High idling in gear and taking long time to idle down at a complete stop

    Problem solved, had to replace upper plenum. Check out my smoke test if you like. https://photos.app.goo.gl/CanpoZzDTDxaWLR78 Hey I have an issue and based on my search most have the same type of high idling issue on older TBI models. Just had my new engine Dyno tuned with the 0411 PCM swap...

    Won't idle, new 5.7 vortec crate engine, all new everything and 0411pcm

    Thanks, unfortunately the shop that installed it won't listen to me and connect to the computer to make adjustments or see what the data tables show. I checked the distributor and timing marks today, everything was like I figured dead nuts because no codes. The fuel pressure is good. same MPFI...

    Won't idle, new 5.7 vortec crate engine, all new everything and 0411pcm

    Watch the video in the link, https://photos.app.goo.gl/kkNjVZGdbMum4dF88. It won't idle ,no codes on new ATK HP74 315+HP crate engine. Fixed vacuum leak and now it runs worse than it did sucking air past injector assembly. I honestly don't think they tuned the 0411pcm correctly. I'm beyond...

    answer to any 4l60e trouble

    I just come across this post and thought I'd offer my 2cents with anyone having issues with a TCC SOLENOID CODE P1860 on 95-00 4l60e and 2000up p1870 on 4l60e,4l65e,&4l70e. I had a freshly built 4l60e 1000hp stage 2/3 transmission built in 2016 that we replaced solenoid and valve body to find...

    Speedometer was only off by 5mph and now progressively off? Why?

    So if the thing is calibrated correctly in the pcm, the 120 speedo is always going to be off if I understand you correctly? Is there a way to adjust the pcm? I have the 0411pcm in my truck. I'm 42 and used to carburetor engines and actual speedo cables and gears in the transmission. This...

    Speedometer was only off by 5mph and now progressively off? Why?

    I haven't bolted them on yet but according to all my research the pacesetter long tubes from summit.Here is the link. https://www.summitracing.com/parts/PSM-72C2262/applications/drivetrain/4wd Also if you have an EGR delete you can do away with the tube and put a plug in the intake and a cap on...

    Speedometer was only off by 5mph and now progressively off? Why?

    Awesome, thanks for your help. I've been searching 2 days online for a definite answer before I posted on here. I'll have it recalibrated next week when I get my initial crank up tune on the new crate engine. I'll have it checked again in a couple of months after the initial break in and I put...

    Speedometer was only off by 5mph and now progressively off? Why?

    Has anyone found a solution to this? I just had my 97 5.7 k1500 recalibrated when I installed the 0411pcm for a performance engine upgrade. It read dead on with the OEM 100mph speedometer. Then 2weeks later I did the 99-00 Escalade 120mph swap. Now my speedometer is reading anywhere from 5-7mph...
