Re: HELP Running lean with 50lbs injectors
Now ya have me thinking. Before it was dot to dot. When I went to the 50s I also set the cam 4 degrees advance. Thought that would bring my power band down in the lower RPMs. But I just can't get myself to beleive 4 degrees could cause this. Maybe I need to put it back to straight up.

Re: HELP Running lean with 50lbs injectors
You have to watch degreeing cams. Lot of the cams out there nowadays will have so much advance or retard built in them.
I know its a pain in the a** but I would put the cam back 'dot to dot'. I gotta feeling its going to fix your problem.

Re: HELP Running lean with 50lbs injectors
What are you using to measure air fuel. If you are using the autometer with the stock o2 you are pissing in the wind. All that does is tell you if the o2 is switching. Unplugging the mass sir with 50s will make it so rich it will foul the plugs out in no time. Get that thing to a dyno with a real wideband then make your next move. Headers glowing red is usually from Low Initial Timing. Double check the balancer and make sure its not spun or damaged. Keep us informed.

Re: HELP Running lean with 50lbs injectors
Put that cam in straight-up. It probably has a 112º LSA and a 108º intake centerline? That means it's got 4º advance built in.

Re: HELP Running lean with 50lbs injectors
degreeing the cam in at 6 degrees advanced will only lower the power curve where it comes in faster. Exaclyy how did you degree the cam? was it with a degree wheel.

Re: HELP Running lean with 50lbs injectors
No degree wheel. On the cranksproket there are 3 position went with the on that had A on it. I talk to a couple of engine builders and they say 4 degrees either way won't(shouldn't) cause the headers to glow it just moves the powerband up or down. Talked to another person who said I MUST HAVE A CHIP OR PROGRAM. I plan on pulling the cover off tonight, But I agree with shankin if I unplug the meter it should foul the plugs in a matter of seconds due to the 50s and it don't.

Re: HELP Running lean with 50lbs injectors
yes a chip or programmer would definitely benefit you but I still think the cam being installed 'straight up' is the root problem.
