TBI to carb questions.

Firstly i can not figure out how to search. I searched for every possible thing to search for and it gives me the same exact posts each time that have NOTHING to do with this swap. *rant over*
Now i know this was descused befolre but i cant find the thread. I need to know what all is involved just as an ivestigation. As of now my plans arnt to do this swap but if its easy enough i might just consider it. I need to know what all exactly to do i know all the basic stuff like new intake and dist. and stuff. but how would i do fuel, make the speedo stil work, cruise control still work and every thing else.

Well you dont need a new distrubutor. It will still work all it needs is keyed 12V hooked to the positive on the coil. Thats what im running in my 454. You will need an intake with the 87 up bolt pattern. Your speedo should still work even without the injection harness hooked to the computer. Your cruise will work if your speedo does. I'd used an adjustable fuel pressure regulator with a return line to cut pressure to 7 psi.

Cool good info. How will the dist. vacume advane and centrifugal advance though?

Just get a distributor for a 76 350 or simillar. Mine is supposed to be on a Nova. Its curved fine for me. /forums/images/graemlins/k5.gif

I did this to my 89 TBI, Used Edelbrock Performer #2104 manifold, picked up a HEI distributor, eliminated the electric pump and used a mechanical one and recently replaced the old Q-jet for a new one, nedless to say it's running great.. /forums/images/graemlins/thumb.gif

What problems did you run into with this. How did you get rid of the tbi harnes but stll make every thing work? How did you just eliminate the in tank pump? does the speedo still work? what about the other guages?

Mine basically came off a 89 and I sold the tbi system and the guy I sold it didn't want the block so I got the intake and used the distributor and carb off the stock 84. If your speedo is mechanical it shouldnt make a difference.
