I have a mod man intake on a real mild 499. We run two 1 inch spacer/restictor plates and two edelbrock 800s. They are jetted 113/107 and i stepped the rods one step leaner on the idle side. Its run a best of 10.0 in limited tests due to us keeping it restricted back to a 10.50 index. I want to play with it and see how much is left in it.

You have a lot more plenum with the big indy intake as compared to the mod man i am running. How did you get to 113/113? Did track testing show the secondaries as being lean or dyno time? ok... somewhat mild.

So its not a true comparison. I ran 10.10 at 132 this past weekend with the restrictor plates out but the weight was still in the car. ( 70 lbs ) 7875805-IMG_3025.JPG (83 downloads)

Hopefully with some further tuning you will close the gap some. DVW I believe is running 572 ci with his Indy ram intake. Getting old just means you were smarter than some and luckier than others.

It runs decent, drive ability is good, others have used similar jetting, plugs look ok. My O2 sensor is broke. I'm sure there is more in it. Lazy 60 to 330. It would run better if I new how to tune with more than a stone, stick, and an ax. Doug
