The easiest way to go about this will be to use a Vortec TBI intake to reuse the TBI unit from the '87 on the Vortec engine. Reuse the sensors from the '87 on the '97 Vortec engine as well.

The spider/poppet EFI set up used on the '97 Vortec isn't a favorite among builders, anyway- even though they work OK for a stock or mild application. You could use a TBI adaptor (others are available, I believe Trans-Dapt are the least expensive) on a Vortec carbed intake instead of the GMPP TBI Vortec intake, this option could be cheaper if you can find a used Vortec carb intake.
