351 w throttle lag???
I have a 68 with a 351 w. I swapped the stock air filter housing with a open chrome one. Now have a lag at acceleration that was not there before. Any ideas as to what might be going on? I checked the throttle linkage and it is not hanging up so I am stumped. Thanks

It may be lean because if you are running gas that has ethanol the float valve is breaking down, and or, the carb jets need to be increased in volume because of the effects of the ethanol. I just read this months edition of Mustang Monthly and it goes on about the eefects of ethanol in our older cars. It struck me because my 70 Mach 1 has been giving me fits recently with "stuck" floats and abnormal atomization from the jets. I'm betting that ethanol is the culprit. The article recommends changing out the float valve every 6 months. Either that or drive the car everyday. I know I have lost about 3 miles per gallon in my vehicles since the introduction of ethanol. It makes sense that the only vehicle suffering performance effects is the one that "sits" in the garage most of the time. Up until now, I've never had a problem.
