    '88 TBI 350 - multiple personalities

    Copout - guilty indeed. While wagering TBI parts bill against carb swap bill, quadrajet & HEI thoughts came to mind. GAS (gear acquisition syndrome) strikes again. TBI base is okay because the IAC came out broken, but in one piece. Thank you though :) The injectors drip inbetween fuel pulses...

    '88 TBI 350 - multiple personalities

    Haha, good points all around, HotRod. Thanks for the laughs on an otherwise deflated day. Just put a new trans in and was looking forward to a test drive. EGR, plugs, cap, wires are new with maybe 3000 mi on them. The injectors spew fuel out. EGR and IAC get flooded with fuel every time I've...

    '88 TBI 350 - multiple personalities

    Vehicle is a 1988 GMC Vandura 2500, TBI 350. When cold sometimes it stumbled upon acceleration. Sometimes it idles high and slams into reverse or drive. Sounds like an intermittent vacuum leak, but now the problem is compounded. Vehicle now won't start without 1/2+ throttle opening. Runs very...

    Planning a 700R4 to SM465 swap

    Gotcha. More things to consider . "When in Rome," heh. Had a Saturn engine rebuild that got a case of the "while-I'm-here ...." bug :D

    Planning a 700R4 to SM465 swap

    :D HotRod, I'm going by what the 700R4 does. A 700R4 in OD @ 65 turns 1848rpm, assuming a 3.42 rear with 220/75/15 tires. If I used the SM465 with the 3.42 gears it'd be really different from how the van is stock. That being said, I thought 1848rpm @ 65mph seemed low. Would be nice to see a...

    Planning a 700R4 to SM465 swap

    Been thinking about rear end options; the 2.41 rear (GU1?) seems like a good option for bringing the SM465's gear ratios into a useful Vandura cruising range. I'm not sure how to go about getting that, though. I found a 2.41 pinion & ring gear on eBay for pretty cheap, but that's only one...

    Planning a 700R4 to SM465 swap

    I keep forgetting about car-part.com - thanks for mentioning it. Some SM465s pop up there too if you punch in the right vehicle info. Craigslist double-shifter van is a great find :D Looks like a real friendly guy who'd own that thing. Installing the stick backwards was my hope -...

    Planning a 700R4 to SM465 swap

    Whoa, looks like the NV3500 is a pretty good choice after all. There are a few on Craigslist well-priced, too ... hmm ... might be back to the drawing board for me. Well, work early tomorrow morn - gonna have to call it a night for now. Thanks for your help guys - got some new thoughts to...

    Planning a 700R4 to SM465 swap

    Next time you see her you can tell her how a junkyard boy with a creepy van outside Philly is jealous of her

    Planning a 700R4 to SM465 swap

    Wow man, if only I could grab the parts right off that page :D Finding that linkage would be so hard I bet. I know of a truck junkyard about 10 miles north of me where I got a few things for my '86 F150 and a new grill for the Van (took it from a Suburban), but I might be lookin for a long...

    Planning a 700R4 to SM465 swap

    Wow! Yeah that manual would be awesome to have a look at, Jay. Fortunately and unfortunately, planning this swap is definitely an endeavor in "fun" - since I was a little kid I always wanted a big, stickshift van. Eh, we all have our dreams :)

    Planning a 700R4 to SM465 swap

    Yo that MY6 A833 sounds pretty cool ... helluva a lot easier if I got my hands on one of those. Thanks for pointing that out - I wasn't able to find out what manual trans the vans came with

    Planning a 700R4 to SM465 swap

    I'll keep some passengers handy, hahaha With the inner hood off the van, the top of the bellhousing is to the right of the driver's seat; reckon a toploader SM465 would place the shifter inbetween the front seats

    Planning a 700R4 to SM465 swap

    Hey all, I'm hoping to get some info from GM gurus, at whatever price I have to pay (I'm prepared to be very laughed at). I have an '88 5.7 TBI Vandura 2500 with a 700R4 acting up, and I don't want to play games - well, not with fixing an automatic at least :D Don't want to spend more than...
