Good product. | | | Re: 1997 Chevy Express Cobra Conversion | Joined: Apr 2007 Posts: 249 Likes: 59 G Van Man | OP G Van Man Joined: Apr 2007 Posts: 249 Likes: 59 | Nice score; especially on the OPTIMA battery. Good product. Thanks! I spent some more time over at the shop last night. Working on building trans cooler lines. The Trucool D7B I have been running compared to the factory cooler still laying around the shop. DB7 is roughly 50% larger(wider and taller) and roughly twice as thick. It probably has 3 times the cooler fin surface area the stock one does. Replacing the leaking factory lines and quick connects with AN on it too. My previous converter was a 10" job that stalled 2,700 rpm and the D7B plumbed in after the radiator cooler kept the trans around 160°F max even towing my travel trailer. The condensor has a nice trans fluid stain on it that is filled with dirt and it is absolutely full of small rocks and debris. Good thing it is getting replaced with a new parallel flow.

My van is a cobra too but from '79. https://www.vanning.com/threads/ubb...e-ultimate-custom-camper.html#Post403571I wonder is it the same people or did the name just get sold on.

My Cobra was made in Elkhart, Indiana by Advantage Enterprises. Advantage Enterprises built Advantage, Cobra and Rockwood conversion vans. I know Cobra was around until atleast 2005 as I have seen a 2005 Express with the Cobra conversion. I have also seen a mid 90s G-van that was a Cobra as well.
