throttle body opinons?

[Tylerrabbit93]

anybody own the Holley high-flow EFI throttle body? (http://www.summitracing.com/parts/hly-500-6s/overview/) if so how do you like it? thinking about going carb but currently trying to sell the 4l60e for a turbo 350.

What are your actual goals with the engine/truck? Because otherwise nobody can really give you helpful advice.

If you thinking putting it on a stock 350 then you are wasting your time and money. You will just over fuel that thing and make it run like crap.

Overall goal is as much power while still being able to daily drive it. Already has roller cam, forged pistons, rocker arms. Later on I would like a more aggressive cam and aluminum heads, haven't really looked into which heads or cam I'm getting yet though

If I were you I would get a 255 gph fuel pump and modify the tbi to adjust the fuel pressure. Increasing the fuel pressure gives you more fuel and better spray atomization. After doing a lot of modifications like you mentioned a wideband is highly recommended to help get you proper air fuel mixture.

If you want to DD it your going to want to keep the overdrive. Also the Holley injectors and fuel pressure regulator suck.
