Who built the engine? I'm not thinking that there is anything wrong with the assembly but sounds to me like the cam is advanced- thats bad for an injected 5.0. Lots of engine builders recommend advancing cams 4 degrees. A engine builder that doesn't have a lot of injection or Ford experience might do something like that. Just an idea....
I bought it from CREB builders in Rhode Island. I actually swapped out the timing cover and verified for myself that there was not any advance on the cam, at least I think I did. The sprocket marks were exactly lined up with each other, I think that means no advance on the cam install.
He said his timing is 14 which is pretty fair, now as long as his total timing is in the low 30's then I dont see any problem with his timing. If all cylinders are holding pressure, everyone is firing, he fixes his lean problem and his timing is working then I dont see what else it would be besides drivetrain soak. He's got a weak ass cam and hes pushing through an old 4 speed, dana transfer case, and a built 9 inch with big tires. This isnt a mustang so stop thinking with your mustang heads. I say change the cam, break in the engine, drop the timing to 10* making sure the distributor is correctly advancing, and make sure your A/F is around 13/1.
Yeah I am definitely lean. At anything over 3600 RPM I am over 15/1 A/F ratio. I am running the C&L Mass Air, the tuner tried to get my A/F in better shape with my pressure regulator but couldn't get it any better than that, so I guess I need to switch Mass Airs, or get a chip, or I read that if you run a 19# sample tube with the 24# injectors that will fatten it right up.
Thanks
Hey folks,
I was just out in the driveway messing with the Bronco, and guess what? The guy had the thing in four wheel high instead of 2 wheel high. So he was spinning the entire T/C, front driveline, front diff., front axles right out to the hub. The hubs weren't in so the wheels weren't turning. I guess this guy has never dynoed a 4x4 before. I would think that had to soak up 60 tyo 80 HP turning all that crap.
