347 in and running

I got it to idle and run. I have a pretty nice vacuum leak somewhere. I'm only making 3" at idle. I had a lean pop that I could hear through the intake. I hooked my wideband up and it showed 33:1 lol. I ended up putting the idle fuel in the PMS to +114% idle fuel to bring the idle a/f to about 18:1 which is a hell of a lot better than 33:1. The excess fuel i need is probably due to the big vacuum leak. I also have a high idle, about 1200 rpm. It drives kinda crappy, it bucks and jerks. I think once I find this leak, the car will run a LOT better. I'll probably have to lower the idle fuel too. I'm not worried about power tuning yet, just fixing the vacuum leak and idle/driveability. I also gotta change the oil too. Hopefully it stays dry tomorrow!!

I replied in the 5.0 forum.

Do you think this guy could do my combo in a year or so when Im ready? Only thing is, I would want it assembled.

Let us know how it's running when it's all tuned.

He assembled and tuned mine and it runs GREAT! You won't be disappointed.

I got a Vortech SQ like you on a 331 w/AFR 185's

I need to update my siggy
 
lol! The header decided to melt one of my msd wires a while ago so I had a few spare FMS wires in the garage :D

Its pouring rain today so I didn't work on it. I picked up a few cans of carb cleaner so hopefully I can trace this vac leak down.
