Glad to hear there is another Street Rod guy here. The cool thing about a street rod is there are no rules. Each car gets built, modified, painted, and accesorized in the manner that best pleases the owner.
Corvettes can be a little more difficult to deal with, but worth it.
The 1982 pump will not make enough pressure for the tuned port. However, I think there is something really trick you can do here. If the 1982 pump sending unit will fit into your tank, or if you can get a 1982 fuel tank to fit in your car--simply replace the pump for the 1988 T.P.I. Camaro pump.
When I put LT-1 motors in 1988 and up Chevy trucks, I simply swap the pumps as noted above. It works perfect. Think how trick that would be to have the pump in the tank just like the factory.
It is good you have the project planned for the Winter. This will give you time to detail out the T.P.I. and gather all the related parts to minimize the amount of time the car is down.
The Vette brackets may work on the T.P.I engine. The problem usually comes in with clearance in front of the throttle body housing for the air cleaner vs. the V-belts.
A fellow in my town has a 71 Shark with a 1990 Tuned Port engine and 700R4 trans. He ran the 90 Corvette brackets. It looks nice, but the 85-91 vettes have the air pump. Even with the air pump delete, it clutters up the engine bay. However the 85-91 vette brackets use the short water pump that gives more clearance on the radiator. I think you should try the Camaro brackets as the air pump is mounted low and can easily be removed. The only problem is the camaro uses the long leg pump. Don't know if it will rub anything.
Sounds like a fun project.
