[Cobraqcca]

Hi All-

So, not to beat a dead horse, on the EFI vs CARB debate, but, if you have a carb, how bad does it actually stink of gas. Running or just in the garage??

Original thought was to put on EFI and go - such has not been the case!!

I have a PJIII EFI on my 427W Ford Racing Crate Engine and I've had a lot of problems 'dialing her in' or even getting her to idle well....can get close but not right on...!! It started out with a defective TPS - that I think blew the ECM and now my O2 sensor appears to be fouled...I'm fed up!


I'm thinking I may want to go back to a carb for simplicity sake. No O2 sensor, TPS, ECM, AIR mix control to eventually go defunct...no electrical connections to corrode or disconnect!! And I won't have to spend all my free time trying to figure out all the tables and programming!! Besides, I think I'd be able to tune a carb just as well...at least for my driving. Only question is some calculations say 600cfm (street) and others say 750cfm (race)! Anybody done either one or both?? I'll drive maybe 5000 miles a year MAX!! At 535hp and 545 torque I don't know that I'll need the extra 150cfm - unless they would basically run the same except at WOT!!

Suggestions.....

Thanks,
Gary
