5.7 swap questions?

Thanks for the pics on your build up. How did you get your gauges to work? Ive heard that this is a problem with this kind of swap. Now you also did the carbed version. What were your pros and cons? Did it affect mileage? what about power? Your 1/4 mile times, i noticed they were good, but could you have done better? were the tires slipping at all? Im sorry for all the questions. I just cant jump head first in without gathering all the info that i can. THANKS!!!
