my 84 camaro i have stripped of the computer and iwas wondering if i put a lsx in would it be worth it to put a computer for fuel injection or jsut put a carburator on it

 

The choice to go EFI or NA is really up to you but the NA carb'ed route probably being the least costly.

 

Rarely.

You still need a "computer", the MSD (or other) control box that replaces the PCM. If you have an electronic transmission, you still need a box for it as well. Plus the intake manifold and carb.

A complete "dropout" - engine, transmission, harness, PCM - will have the computer (PCM). The car's original computer is no longer needed when you have the PCM.

Everything else you need for the swap will be needed whether you do carb or stick with the (superior) EFI.

Yes, yes, there are members that have carb LSx cars, and yes, they are fast. They are also race cars first, street cars second. And are not emissions legal, nor can they be made to be.

 

I think it depends on what motor you start with. If you're looking at a budget project, chances are you're starting with a truck motor, which is going to require a lot of changes anyway... intake, accessories, computer, harness, etc. In a situation like that I could see the cost of retaining EFI easily matching or exceeding the cost to convert to carb.

But... with a car based LS motor, you've pretty much got everything you need for the EFI.

As for transmissions, if you want to retain the 4l60e, then forget about carb. The electronic control module for the trans is about a thousand bucks, but if you've got a 700R4 to use, the carb idea isn't too bad.
