Go for it Tom you can sell what you have on the car and recoup half your costs. A word to the wise however, make sure the replacement plenum has ALL the tube connectors so you dont have to take any off your plenum when it comes time to sell. I bought a spare plenum to expedite my down time and it was missing a couple of tubes that Jeffvette had to scrounge around for. The porting and polishing job is a very labor intensive process as you well know so this sounds like the best least amount of down time option for you. You should see about 15 HP inporvement if you match port the heads as well. About 30 HP if the package includes a set of long tubes. Keep in mind you will need to get your prom retunned due to these mods. Have fun. GC
