Well last night I installed my MSD 6A in about 2.5 hours. The hardest part was mounting the Dang BOX. I ended up takeing off the small grill under the windsheild, and mounted the box up above the heater hoses. I put it all together and took it for a test run and once I got on the gas I could tell it had better throttle response. Once I figure out the proper gap I will let yall know about the Gas mileage later when I can do it on a long trip. GO Easy and many thanks to Phillip at MSD he is a great guy (he even was able to call me at work and help me out.) "Philly87 on CK5" Later KEN DANGIT it's not a bronco!
