That is just sexy. Port shot of nitrous in the upper of an L35. Guy has to be spraying at least 100 on it, probably closer to 150. I venture it would make a CPI engine a great deal more entertaining.

Nice score, and great troubleshooting. Amazing how quickly some people can "give up" on a vehicle.

The other source you might want to consider getting is on Ebay.That is the factory service manuals and electrical supplement manual for your yr van.They are normally pretty cheap and way more informative than anything else you could get.They where published by Chevy for the dealerships.Just do a search where you find people selling them used.
