Question about removing a TBI from a 4.3

I bought a donor S-10 Blazer for my '47 coupe. It has TBI and I am in the process of removing all the wiring from under the hood and under the dash to run it. When done, it would be a S-10 basically power train-wise. I would also reuse the gas tank and emissions.

I had a reality check today, wondering if it wouldn't be easier to just put an Edelbrock intake on it with a carb. The five speed manual trans would work fine I assume with a mechanical speedo cable instead of the sensor, maybe I would need another tail shaft and housing? Could I still use the '92 factory cruise control?

the cruise won't work w/o a computer..... for the speedo, just get an electronic speedo.

if you wanted cruise, the Autoloc unit sells around $100 and some parts stores carry it, or there are a ton of internet vendors.


if you stay TBI, don't use the s10 tank, for around $200 you can get a brand new tank for your car that fits like the original and has the bosses in the tank for the fuel pump. www.streetrodhq.com has those

Cool thanks for the information. I just have no idea what is available these days. The more I read the more I realize how little I know. I think I'll go with a carb and a nice looking intake and air cleaner then get that aftermarket cruise. I can still use the EGR and vapor canister plus get a really nice distributor and headers. An electric fuel pump and the electronic speedo will work good too. I didn't realize electronic speedos were available.

Tuning on the carb might be a little hard with the EGR.

Carburated engines have had EGR's for years. I suppose the manufacturers of the pretty intakes have EGR built in so they will be legal but I'll check when I get that far.

I know that, EGR has been around since the 70's and is on many carb engines... Carbs have to be tuned to work with EGR's as the EGR messes with the fuel mixture.
