TPI to Carb

[jefferson123]

I know this has been disscussed many times,but i need to know.I have a 1999 2500 4x4 and i want to put on an edelbrock with a 600 cfm.Is thier anything else i should know like distributer? or automatic shift cables? Please help.
I have had enough of this pile of **** fuel injection.Very costly airflow sensors,o2 sensors and the list goes on.

It can be done but it is an expensive conversion and you will be running afoul of federal and/or California smog laws in doing so - potentially subjecting yourself to a $25,000 fine. If the engine is an LS type (Vortec 4800/5300), you will need a special front cover that fits a Ford small block distributor (it is available, can't remember the GM part # off the top of my head), plus a special carb intake. If it's a small block Gen 1 engine, you will need a carb type Vortec intake (earlier ones will not work), plus a vacuum controlled HEI distributor.

It will run like crap, cold blooded and I know of one doing this in a 1991 Chevy truck.Was converted to a carb,would not run right,had to pump it a few times and ran like crap.Electronic Fuel Injection is more reliable than a carb.The carb has more parts than EFI and that is one reason why automakers switched to EFI.

Thanks silicon but not worried about smog laws as i live in Northern Canada,and they dont check this far up.Engine is a 1999 vortec 5.7 and i planned on putting on a edelbrock vortec,but wasnt sure of HEC or automatic trans shift cables.

Automakers did not switch because of moving parts,they switch because it was more efficient and responsive in MOST cases, but not all.
As far as a 91 goes thats TBI not TPI,and thats simple to change to a carb,and make it run efficient.

You will need an aftermarket controller for the 4L60E/4L80E tranny (not sure which one you have). TCI makes one GM might even make one. There are no shift cables. You could switch to 700R4 and use a vacuum switch to do TCC lockup but the 4L60E/4L80E will require a controller.

Here is the link to TCI's Controller http://www.tciauto.com/Products/Electronics/default.asp

Ebay may also have some. GM Performance Parts may also make a controller.
