thats what i need to know, what would be best for street and strip, the cars weighs in at 3,070, may be i need to go with a shorter slick, less gear, then go with a taller tire for street use
That's not bad. I don't think high 12s are outta the question if you can drive well and follow the MP suspension manual. Read the 13 second recipe in the Mopar book. Although it says 3.91 gear, the maximum weight is well over what you are. I don't think 12.90s are out of the question. Might take some time tunin to get there. the book also says only 9 to 1 compression and you probably have more. You also have more camshaft.
