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 .
Here's a pro point for EFI. LS1 motors seem to be in a world of their own. I've seen LSx based cars run a cam on the street with great manners that would simply not be possible with a carb'd application. The computer is constantly trying to smooth out the idle. The GM setups seem to be a little better at this then the Ford setups.
When its working right and all the parts are working in harmony with each other,.. EFI is great. I'll never argue that. There are guys tweaking their own EFI setups on 5.0 and 5.8 based setups. More power to you guys. You guys know what your looking for when there is a problem. I'm one of those guys that is too far out of the loop,.. too old,.. and lack the patience required to learn it. The whole premise of my post was not to put down EFI. Its already been proven on stock long blocks that EFI can pick up as much as 30 - 50hp more then a comparible carb setup. The carb is not very efficient. Its not the choke that causes them to not get that great of fuel economy,.. its the lack of efficiency,.. and the common bigger is better methodology that some guys throw on the biggest carb they can find. A carb,.. like EFI,.. can be tuned for economy or power. For power they are setup to dump more fuel with each push of the pedal,.. jetted richer,.. and basically,.. completely inefficient. The economical approach is the complete opposite,.. choke the motor down with as small a carb as possible,.. lean the damn thing out and use as little advance as possible in the ignition.
Where with EFI,.. you can get the best of both,.. they are so efficient at what they do,.. 300hp and 20+ mpg has become common place today,.. where 15 - 20 years ago,.. a 300 fwhp Target Master crate motor from GM was considered a bad ass setup,.. but no one ever expected more then 10 mpg out of it. My 396 Chevelle with Q-jet carb got 10 mpg on a good day on the interstate. My 455 GTO was doing good to get 6 - 7 mpg. But hey,.. I had a 20+ gallon fuel tank,.. gas was 0.66 a gallon and you could still buy 101 octane leaded gas. Cops used to come watch us street race in Ocala,.. Z93 radio station came out one night and played music at our Ben Franklin hang out on the blvd,.. and the DJ said I want to see 2 cars line up and I want to see some tire smoke. 6 cars went out on the street,.. all of them power braked at the light,.. they smoked out the whole plaza,.. and no police ever hassled anyone. Those were the days. Now you have little punk white kids who think its cool to act like a black guy from the ghetto and ruin it for everyone.
