what're you running in your 440s?? i know stock is autolite 85s. but the motor i've got is a little hopped up. idk how much because the customer bought it this way. its got a cam for sure but dont know specs (pretty lumpy though), weiand dual quad intake with dual 600s along with lt headers and 3" mandrel bent exhaust. any recommendations are welcomed. please put a reason to why you use the specific plug too.
Thanks!

 

Matt -

The Autolites actually have a good rep. I've been using the Accel shorties (AKA peanut plugs) for better wire to header clearance.
