lol.. i just said that to be a smart ass . guys calm down . carbs have there place its just not on my MOD motor. but with my car i have made well over 600whp and starts up and drives every day (not saying u cant do that with a carbed motor). as for efi and sensors i have a cheap comp program that plugs in my data port , i can look up each sensor and see if its working in the proper voltage range. takes guess work out of trouble shooting. but i would never put a carb on my mustang (i would if it was a push rod motor). im restoring a 47 Pontiac silverstreak i would never put efi on it .
