    Newer GM crate motor with TBI?

    Ah. For some reason I recalled that you had a 400 cid in there

    Newer GM crate motor with TBI?

    Yeah, if I were starting over, LS. If I have to scrap TBI, I'll keep the crate engine and get a beefy TPI system or alternative. There are so many options, just not many that I know of that will be relatively-easy to make compliant with smog checks. I'll keep tabs on your project and chime...

    Newer GM crate motor with TBI?

    Sorry for the late reply. I've not been on in years. To answer your question, it worked out, but I had to pay a lot to get it running right and get a custom chip burned to match my config. The chip Blueprint Engines "customized" for me was way off. The 454 injectors I could only find used...

    Flat Towing w/Atlas 2spd and 700R4 AT

    Just in case this is helpful to anyone else, I flat-towed it with the steering unlocked (of course), the trans in park, and the Atlas in neutral and it went well. Thanks again for everyone's help.

    GM TBI 200 RPM idle

    I got my TBI running well, the timing is on, injectors flowing, new plugs, wires, cap/rotor etc. It revs smoothly and idles, but barely and at 200-300 RPM. I know the ECM controls the idle speed and that there's no manual adjustment without mods. I'm trying to understand how the ECM controls...

    GM TBI swap,running way way way rich..need help

    Your symptoms sound exactly like what I was experiencing with my timing issue on my GM TBI just a few weeks ago. Mine would idle rough, run rich, rev very slowly with hesitation to about 1800 RPM, then backfire and die. Timing was the last thing I checked because I "knew" the timing was...

    Wanted: 700R4 inspection cover

    Wanted: Inspection cover (AKA flywheel cover, torque converter dust cover) for a TH700R4 4WD trans mated to a SBC. I think the trans is ~1991 if that makes a difference. thanks Edit: Also need the bolts or I could pick some up at the hardware store if anybody knows the size

    Flat Towing w/Atlas 2spd and 700R4 AT

    Thanks for everyone's help. Here's what I found out from AA: For the short runs I'm doing, there's no need to remove the driveshafts, so putting the tranny in park will be fine. If you're flat towing hundreds of miles, they recommend removing driveshafts.

    yeah, it's a 1990 YJ with a 1991 GM 350 ECM OBD I

    Flat Towing w/Atlas 2spd and 700R4 AT

    It's going to drag on longer than 15 days, unfortunately

    Brilliant! Does anybody know if doing this front-wheel-drive idea would prevent a shop from being able to perform an emissions/safety inspection?

    Flat Towing w/Atlas 2spd and 700R4 AT

    I'll try AA again even though the last interaction I had with them was not very helpful and took them weeks to respond.

    Flat Towing w/Atlas 2spd and 700R4 AT

    yeah, joking. Reminded me of the time though that I had AAA tow it instead (I considered doing that again, but depending on the tow truck driver, they might not tow it)

    Flat Towing w/Atlas 2spd and 700R4 AT

    LOL AA as in alcoholics anonymous? AAA won't do unregistered vehicles (except that one time I tipped the driver extra for pretending like he didn't notice) and buying a trailer to tow short distances isn't going to work for me for several reasons, mainly because I don't have any intention of...

    Flat Towing w/Atlas 2spd and 700R4 AT

    So I can't send you a bill if you're wrong? ;) Problem with pulling the driveline is that every time I take it to a shop, I'll either have to re-attach the drivelines in their parking lot at dropoff and remove at pickup or let them tack that onto my bill each time.

    Flat Towing w/Atlas 2spd and 700R4 AT

    I just installed a tow bar on my YJ and have never flat-towed a vehicle before, so I've looked all over the net trying to find solid info on how to do this while protecting the trans and t-case. What I'm finding is a lot of conflicting information (even Advance Adapters has conflicting info)...

    Yeah, picking up some whiteout on the way home from work today. Thanks for the suggestion.

    weird timing light problem. Any ideas?

    Yeah, definitely on #1 and tried things like moving the pickup clamp to a different part of the wire, checking that the wire was separated from other wires and metal and wasn't arcing, etc. Made sure the ESC was disconnected.

    weird timing light problem. Any ideas?

    383 sbc TBI using ~1991 350 donor ignition parts When using a timing light, I see several marks at once on the balancer instead of one clear mark. The balancer has only one actual mark on it, but when the engine is running, it looks like it has at least half a dozen marks showing up. I've...
