Default emission mess & needed repowering

Here in NC , for 1981 vehicles, the only emission related requirement to pass inspection, IS: the original emission equipment has to be installed, e.g...smog pump, AIR, computer, etc..AND "Appear" to be functional..(.this appear is a nice loophole.)

I can't find a needed PROM for a manual tranny application, so I want to swap out the computer controlled dist. and carb. for a non-computer controlled set-up.

I doubt if the aircleaner will be removed from the carb during inspection, but the 81 dist has the coil on top which would be noticeable if it's replacement was different. I am partial to the Quadjet, Eldebrock is ok, but smell-no to the hOLLYS.

This squit is wearing me out! I would appreciate any and all suggestions
thanks, jim
ps: there is no tailpipe or any other testing or test.

hypertech makes one. You can also get a custom one burned for between 100and 150 dollars. With a custom you can leave all the smog stuff on just use blockoff plates and so on and the computer will not see them.

I got a 4spd chip from hypertech when my ECM went south and killed the original. If you are not going to far from stock it is a nice setup. IMHO the visual test is meaning less but one of the hardest to pass if you want to modify you car

Default Mr. L and stickboy

thank you very much for your imput! Mr. L, actually WHO will burn me a new PROM? A few friends have also said this , but no one knows WHO does this or WHO I can call.
Stickboy, hypertech requires you to run minimum 93 octane with their chip. With gas at $3/gal, no thanks; I want to stick w/my 87 which the car runs fine on. I thought Hypertech would be my ticket until I found that out.
Thanks again, jim

I wasn't aware of that, however my comperssion was bumped up to 10:1 and I was running 89 in it with only occasional pinging.
