Being the vortec heads flow far better than the stock TBI swirl ports ever dreamed, then you will need a custom chip burned and likely some dyno time to get the tune correct with a TBI. If you go with a carb you will need a older HEI with mechanical and vacuum advance. You will also need to reduce the fuel pressure down to around 5 to 6 psi, as thats about all a carb can take.
