It's a 6.4
Now, 10678 miles on this setup without problem
44 run 1/4 mile drag race
12 run 1/8 mile drag race
What's the engine combo and do you have any et's yet?
What size of rear wheel/offset are you using, and what size of tire? I assume you have full tub.6.4L 10:5 comp. so I can run pump gas, 608 lift cam, extensively ported heads, 2 600 cfm carbs. around 600hp and still very streetable. 4500 stall 727 and 488 gears on a 9 inch. 6.50s in the 8th on mickey Thompson street tires so it has to be babied off the line.
