Murray, I don't have the answer to your question...But, I do know that it can be done! As far as wleing a pan bottom inverted, that seems like alot of work, and don't foget that the oil pickup needs to be a precise amount off the bottom of the pan! I would suggest 2 things: first, go to
www.nastyz28.com and look around. It is a 2nd generation Camaro website, 2nd, go to summit.com and look at their healthy selection of pans. They have great customer service at Summit and will be happy to help. i wouldn't even bother mentioning the truck, just tell them what the engine is and that it's going into a 73 Camaro... Good luck with the build!
