1988 GMC Pickup Motor Swap

We are going to put one of those 330 hp GM vortec motors in this pickup, we are switching to an HGI distributor and a edelbrock carb, does anyone know the fuel changes we are needing to make, I'm thinking a 4-9 fuel regulator and then we need to mod a return line to the gas tank? Has anyone done this before, any other items we're going to encounter? One more thing, does anyone know what would be the result of using an adapter plate with the TBI instead of a carb. Is the cam too much for the TBI?
Thanks

88 should have return line to the tank because its fuel injkected. it should but im not 100 per poswitinve.

you needd to run pretty much nothing more than a high out put fuel pump, mounted inside the tank. and cam that the engine can run. or a cusatom cam with custom programmed computer to make everything work right.
