The title is right. I’m putting a 5.3/4L80 in an OBS bronco. I’ve owned this thing for a while and am tired of sbf problems. Not new to the ls scene. Had several GTOs and have a c6 z06 (434ci) now.
I traded a set of sbf heads for a gen 4 5.3. The goal of the build is midrange power and torque as it’s an over lander and prerunner build. Eventually I’ll supercharge it but for now it’s NA.
- what heads does a gen 4 5.3 have? I thought I saw 243 which is what I want. I don’t want too much flow as it would decrease low and midrange power which is where I want to live.
- should I get a tbss manifold?
- I’m keeping it dbc so I need a new throttle body. Recommendations for a non ported tbss manifold?
- Dod delete. Texas speed or someone else?
- I want linkbar lifters. I don’t like ls7 lifters. I was eyeing the Johnson 2116 as I have them in my z06. Seems overkill for this build.
- anyone have experience with the cam motion truck titan 2 cam?
- headers? I have a set of ls7 manifold from my Z06. I might use those but any recommendations on shorties? Kind of uncharted territory.

Hi, I have worked on many race-winning Broncos. The drivers, Ford-sponsored racers, were PJ, AK Miller, Bill Stroppe, Steve McQueen and others.
I would like to help you with your project.

Hi, I was asked to help GM engineers Decode MY 60-2 (58x) crankshaft Target Wheel.
Thus they shared information about LS engines.
MY Bronco "best" engine would be the LS-1 AND I was the first to create/modify a 346 CID LS-1 to post 600 Bench HP.
That engine was fitted with my ITB Intake.
MY information is that they stated the best head was the LS-1/HIGH SWIRL intake port cylinder head.
