87 Suburban tbi to carb swap, question on tranny

If I swap out the factory tbi for a carb and ***** can the computer will my tranny still shift (its a auto trannny) ? (its a stock 87 1/2 ton suburban drive train) does the computer control the tranny shifting ? does the computer lock up or control the torq converter ?

can I ***** can the computer with out causing other problems ?

I ask this in the engine forum I have the some questions about a 87 suburban 350 tbi engine, (I'm lookin 4 more HP & TQ) my motor is hanging on my motor stand now. if i build a mild 383 with a touch more compression & cam, plus headers and 2 1/4 dual exhaust, will my computer still be happy ? or can I make it happy ?

i tried to give my tbi injected 350 a boost with a cam, it did not like it. everyything was ok with a carb, but you will need a distributor. also, be aware that that is not a "kickdown" cable on your tranny. see the TCI web page and search for "TV Cable"

I've done some research on the tv cables, what about the torq converter ? does the computer operate or lock it up ? so with a carb intake & distributor, all I would need is a tv cable ? removing the computer won't hurt me in anyway with a carb intake & distributor and a tv cable ? what about fuel pump in tank ? just regulate the psi for a carb ? any thing else ?




Thanks

two routes to go on converter: use a non lockup type, or use a kit from Painless or others to lock it at a specific speed. i suggest a mechanical fuel pump to go with the carb. ut you can make tank unit work with a regulator
