New guy Engine question
Hi I just got a 1980 Corvette handed down to me. I believe its a L48 350. 190hp is kind of weak lol but it will be a fun car to drive and when I save up alittle more money maybe drop in a 383. Im new to corvettes and older cars all togather. My baby is a 04 mustang. The cars been sitting in a heated garage for about a year now unmoved. I started checking out the motor tonight because I would like to get it running again. Heres my question, I took off the air filter housing and there are rubber hoses running every which way, Ive never seen anything like this. I believe most of them have to do with emissions. I was wondering if I could get rid of all that emissions crap? I would like to dump the smog pump and anything else that has to do with emissions. How could I go about doing this without wrecking anything else? Any help would be much appreciated! Thanks!

before you take anything off of your car check local laws. you might find that you could create a big legal problem by removing the emission equipment on your car. if you decide to remove the emission equipment keep everything in case you decide you want to sell the car in the future.

Not sure why you would want to do this, but......
To answer your question, if you have a 17080204 or 17080207 carburetor you can remove all the emissions components, including the EGR valve and shouldn't have any problems. Just make sure you do each one and test it before you move on to the next. Plug all vacuum ports that you un-plumb.
Don't expect any performance improvements. Those motors in stock form are neutered dogs - period.

Fortunately, your '80 is not computerized (the last!), so you don't have to mess with an ECM messing with your transmission, distributor, carb, etc. However, that means GM had to deal with emissions using non-electronic methods.
If you don't have emissions testing for an '80 where you live (BTW, please fill out your Profile so we know where that is), you can either modify your stock engine or drop in a crate engine. You won't gain much by just taking off or disconnecting the emissions equipment. You've got to improve the flow through the intake, cam, heads, and exhaust to get significant improvements.
It all depends on how much you want to spend and over what time. IMO, it's worth the $$.
