Do you have to have the computer plugged in still our can I eliminate all the wires and computer to?

 

the computer controles the ignition all gages speedo ect.
also the starting cranking cooling
just wandering why caberate

 

long story but I have to go carbed now. I sold all the injection parts. So I leave the computer plugged in but don't use any of the wires coming out of it. That kinda makes no sense. I wouldn't need any of them with the carb and convensional distrbuter.

 

You need the computer to run your factory gauges.

 

okay I'll leave plugged in and tuck in the wiring harness by it. Any of you guys ever done this swap so I can mail you if I have any ?'s. Thanks

 

what are you doing for an intake the lti bolts are angled different from old small block
does someone make an intake for that ive seen em for the votec v8 but not lt1?

 

one more ? is it really possible to put a convetinal dist. on a lt1

if so i like to know becouse that would be sweet in my old tuck

 

You just need a intake for 87 up SBC.And GM has 2 or 3 different intakes for both the LT1 and LT4.

 

will the dist stab in lt1 block

 

Yes once you get the carb intake there will be a hole for the distributer to drop into.

 

having the hole there isn't the big deal, getting the distributor to fit under the cowling area is. People have done it but not without some fabrication.

 

Not true... the fuel level, oil pressure, voltmeter and coolant temp gauges are driven directly by sensors and do not require the PCM. The tach is driven off the ignition. Only the speedometer/odometer is driven off the stock PCM.

Another thing you have to consider is the fuel pump. That is turned on and off by the PCM, and if the PCM doesn't see the low resolution pulse from the Opti, it won't turn on the pump. You probably aren't going to use the intank pump (45psi) for a carb'd setup (5 - 10psi) anyway.

Big problem would be the speedo, but I think with a box from Dakota Digital, you could solve that one.

 

Or you could rip out your stock guage cluster, fab up a panel from brushed aluminum to fit, and mount a set of AutoMeter guages in there with the Speedo, Tach, etc...
