327sbc Carb vs Tbi
Hey Guys and Gals. I have a fully built 327 (3858174) with forged internals and 305 heads (ported and polished). My question is, How much horse difference will be between my 305 tbi setup vs my edelbrock 1406 carb? The 305 tbi setup is on it now. It runs good and pulls strong with the Tbi

Probably very little difference and you will lose fuel economy with the carb

Any Idea about how much HP I can estimate with the Tpi setup on it now? Because I have owned some FAST cars in my days and this feels amazing to drive and mpg isn't bad at all!
