New Emissions issue, what do I do

[chrismoore701]

I live in Lake county Indiana where they check for emissions on I think everything 1976 and newer. I have a 1979 stepside I just tore apart and planned on building a 420 hp 383. The way to get around emissions was to simply plate your truck using 10,000 lbs plates. I just found out today they are not allowing this any more. I could plate my truck in another county, but would it be possible to pass emissions with an engine pushing the hp I am planning on? What do I do????
