1980 emmissions hardware question
I own a 1980 vet,emissions inspection not required in nj registered as a historic vehicle. My egr valve is in closed position & diaphram leaks vacum so I plugged vac line going to it My smog pump is hooked up with fan belt intact. Can I just remove smog belt. Will this help or hurt performance( besides less drag on engine) can I leave my egr blocked off ? will this have an effect on drivability? This is not a show car but a fun driver for cruse nights. Any suggestions greatly appreciated

On AIR just remove the belt--3-5hp increase.
EGR is actually a good thing--it cools the combustion process--thus allowing you to set timing a couple of points higher--thus making the 'Vette go faster.

First check your timing mark is really at TDC. The balencer can slip, giving you and incorrect reading. Lars instructions:
