Default TBI to Carb swap

I'm thinking about swithcing my '88 IROC from TBI to carburated but I'm not sure exaclty what that involves. I'd probably have no problem taking out the the TBI assembly and installing the carb itself but if I need to do anything to the fuel system or anything else it may be too much of a pain. Any info would be appreciated.

You will need to replace your current intake also, You will also need to replace the fuel pump in the tank because the stock fuel pump I believe is 9-15psi and It is too much psi for the carb.

Yep you will need a carb and intake manifold but the fuel pump will be fine you will just need an FPR with a return line provision if you have a return line on the fuel system now. You may also need to get a kickdown cable and bracket for the trans.

I'm sure you could find a nice 350 to put in there rather than wasting time on the 305.

So basically I should save up money and buy either another Camaro with a 350 or a 'Vette or something.

You could do that or just buy a 350 for a swap.

Or if saving money like that isn't something that you are able to do all at once ... just buy parts for your 305 that will swap to the 350 so it will give you more power on your 305 while your saving for your 350.

Since I have a TBI right now, if I bought a 350 TPI engine to swap in I'd still have to buy a new... pretty much everything engine related. That would have to be more expensive than just buying a new car.
