    engine problems help!

    Stick your tongue to the coil wire while a buddy cranks it and see if your gettin enough juice to the spark plug wires............. NO IM JUST KIDDIN! Are you gettin a good enough spark? It should POP when it hits. Its fairly easy to check the ignition module, pickup, and the ignition coil. A...

    Engine dies, then cranks back up.....

    Didnt fix it. It died again this mornin. A few times....... Bought a new toggle/ignition switch and so far so good. I re did all the wires pertaining to the ignition/starting/charging and instead of tape I used heat shrink on the connections. I feel better atleast. The truck did catch on fire...

    What have you done to your square lately??

    Installed a new ignition module today and balanced the tires. Were slow at work so maybe monday Ill get around to somethin else. I would change the oil but it leaks so I just change the filter.

    Engine dies, then cranks back up.....

    Last night it did it and I pulled off and before it cranked back up it produced one hell of a backfire lol. It was bout 12am and Im in the country so no noise. Shoulda heard the echoes. Woulda thought somebody was shootin a 30.06 or somethin. All other ignition stuff is brand new and the...

    Water-logged 350

    Id take the caps off and spray everything down and clean it real good and use engine assembly lube on everything again. Maybe even since your tearin it down just put all new bearings in it. Cheap, easy to do..... I found a set of Vortecs for $550 they got big valves, guide plates, screw in...

    350 Vortec Sluggish...Why?

    The new Chevy/GM trucks have a 3" inlet with a 2.5" outlet. I have a Magnaflow 1 in 2 out in the garage right now that came off a new Chevy. The smaller the number the more tq the higher the less. 2.25 is sufficient with a mild engine. A 1 in 2 out Magnaflow or a "knock off" Magnaflow is your...

    Turbo 350C to 4L60E

    My 350c has a vibration also. Along with a ticking...... Have to shift manually from 1st to 3rd around 35 mph. 2nd will hold upon a downshift but slips like crazy. 3rd is also slippin like crazy. I have a knock like convertor bolts are loose but I have to overfill to get it to hold any gear. I...

    350 Vortec Sluggish...Why?

    350 Vortec Sluggish...Why?

    Did it fix it? I replaced em on my 95 Blazer before. The spider assembly went bad and dumped a 1/4 tank into the motor and hydrolocked it..... Wasnt cool.

    My Mean 350

    Just stop.......... You can build your high hp 383. Remember it needs torque........ Trucks are heavy. IF you build your engine first...... Just know that everything else needs to match. Do it in whatever order you want. If you have 500/550 or somewhere around there, TH400, 3.73's, 2800...

    83 305 wont idle

    This happened to me the other day on a 5.3 at work. Didnt get the EGR tube back in all the way. I was also gonna say if you think the carb had some junk it it you can get a friend to keep it runnin while you put both hands over the primaries and choke it down then pull your hands off real...

    My Mean 350

    Youll like the lowend. Its a heavy truck. If it was an S10 or somethin I could see movin the range up. What are the specs gonna be on the 383?

    My Mean 350

    I went with a XE274 from comp. It lopes nice. Has a nice choppy idle around 900 rpms. Im stock stall with what I beleive to be 3.73's (50mph reads around 80mph) and its trouble if you stomp it from idle. I beleive the 700R4 has a lower 1st than a TH350 dont it? Bigger carb, bigger intake hurt...

    406 stroker?

    Have you gotten your hands on a 400 right now? If you did congrats, they are hard to find around here. And I assume you already know how fast you want to go depends on how much money you want to spend.

    Pull that cam out and put somethin smaller in it. Youll be happy you did. Just cause it sounds badass dont mean it wont run like a dog.

    NO Spark...... TBI 88 GMC 5.7 350

    Carbs are easier to dial in. BUT without the CEL YES it is harder to diagnose. You have to pull each plug wire off and get shocked a few times to find a missfire and all that. BUT you have less sensors and wires. EFI is simpler to a point and carbs are simpler to a point. Just depends on what...

    Carb questions??? Please help!!!

    Edelbrocks are easier to learn for starters and IMO are more "streetable". Holley is more of a performance carb and you can adjust more on a Holley also. Never seen a Quad and if I have I didnt know what it was. Prolly scared me away lol. Also I think Edelbrock/Carters have a cruise circuit...

    Intermittent Random Missfire

    The harness is junk anyway. The guy before me hacked into a bunch of stuff. The PCM is still in there tho...... Im sure its non Cali emission stuff tho. Would it matter?

    Intermittent Random Missfire

    I took the ground strap back off. I remember I took it off last time cause it was gettin smokin hot while cranking it over. It didnt make a difference in anything on or off so Ill just leave it off... Still got a missfire. Maybe some of the wires are bad. I really dont have the money to work on...
