|b00tz||if you really wanna do away with all the sensors and crap why not just find a muncie sm-465 (4 speed standard) out of an old chev truck? theyre tough as nails and cheap as hell.|

if you are going to a TH400, i dont know if your speedo will work right.

plus in 1990 your tranny should be a 700R4. making this swap super easy, basically all you need is
-Holley ByPass Regulator (http://www.summitracing.com/parts/HLY-12-803BP/) Has to be bypass if you plan to keep the TBI Pump.
-I would recommend a HEI Distributor
Steal the 12V for the Distributor from the Pink wire in the stock coil harness. '
Keep the CTS, VSS, OPS so your gauges work.

easiest way around the TBI Pump is to use a Holley By-Pass regulator.
Here is the info on how i did it.

|dnk5chevy||i think we missed the point dont want to convert ecm want to do away with all the computer crap, no sensors ect.ect|

"truck runs pretty good i'm just not that up to date on all the computer stuff nor do i have the budget for it "
Than just leave it alone, there is no cheap & easy way to convert, the ECM also ties into the 700R4.
IF you can find a pre 87 Astro van with a 305/350 & 700R4 with a non-electric carb, grab it up for the parts, harnesses and ECM and plan to send a week changing things over, then pray for the best.
Changing over to a CCC carb makes no sense, just as much computer control and more expensive. For giggles I just checked NAPA for parts:
a Holley rebuilt E4ME Q-JET is $700
Echlin rebuilt parts for mine is $250 + a weekend tinkering around
off-brand parts are $150 and questionable
This really does sound like an idea that should die on the vine, sorry.

|dnk5chevy||truck has 700r4 out of a chevy mini van, no cats 3in pipe into flowmaster w/dule outlets, looks like older style exuast mans,also looks like someone has been in ecm. truck runs pretty good i'm just not that up to date on all the computer stuff nor do i have the budget for it oh no speedo hooked up at the moment its elec.|

"thats it nothing else??"
which transmission does it have?
high pressure fuel pump for the TBI?
Electric speedo? Evap canister? Air injection for the exhaust and cat?
They are all linked together and the ECM won't work without the TBI in the system. Changing out ALL of the wiring harnesses won't be fun or easy, the electronics are not backwards compatible.
Sorry but I think techinspector1 nailed it, much easier to find an older truck to play with.

|b00tz||shouldnt be a big deal, just have to get the new style intake manifold with diagonal bolts,look for one from the newer style motor with the centerbolt valve covers, should bolt right on.|
