Just talked to my buddy Dave
www.tropiczoneracing.com . He built the sister (coupe) car to my 69.
He suggested looking into one of those STS rear mount turbos. Here is the idea. Keep the sidepipes but remove the inner baffles. In stead of exiting out in front of the rear tires, turn them in to a Y pipe at the diff and feed into the rear mount turbo. The air cleaner and oiling system goes in the rear. From there I can run a single feed pipe up the belly (which is wide open on the side pipe corvettes) up to the motor and plumb it in.
There is a TON of room behind the diff on the old Vettes occupied ONLy by the spare tire/carrier.
This has a TON of potential and is very exciting to me. The only real trick is getting the sidepipes to turn in and look/work right.
