I really like those 4th Gen Camaros and they are starting to get cheap. But I won't even attempt to work that complicated engine.

Would it be a bad idea to pull the motor with all that electronic spaghetti and replace it with a simple carbureted small block? Without the engine computer, will the transmission/anti-lock brakes/airbag/etc. work correctly?

The smog check won't be an issue since I'm moving to a state without the smog check.

This probably sounds like a redneck thing to do, but I won't drive anything that I can't fix myself.

you can do it but an HEI wont fit i think you'd have to go with a "crab" cap and external coil... other than that i hitnk it would work(would need a cowl induction hood also)

I have seen it done before. That by itself does not make it a good idea however.

Among the issues is clearance for a carb. The engine is half (or more) under the cowl in those cars as you know. Dunno enough about to 4gens to comment on airbags and such. Maybe the guys at ls1.com or ls1tech.com could help you out.

Try to keep an open mind about the LS1. It is really not that complicated and in many respects is easier to work on than the old school engines. In addition, it runs circles around any old school factory small block and is extremely responsive to mods.

Ok CA72RS, I'll trade you my carbed 355 for the LS1 in the 4th-gen you buy even up. I'll even trade you my 4-speed for your 6-speed so it'll bolt right up for you no problem.

Guys, dont you know that there is products to convert the LS-1 to carb?? MSD makes a box that works with the computer to take care of the timing and ignition.

i say learn to use the electronics to your advantage. its not that hard to work on those cars and the electronics will actually help you if you use them. going to a carbed motor isnt that easy. i haven't seen it done on the LS1 eventhough i know the parts are there to carb it. the LT just has clearence issues that make it difficult to do. but id still say stay with the EFI. do yourself a favor, go drive one or ride with someone for a trip trough the city or something. those cars are so livable, but completely brutal when you get into it.
