EL5 340...
"what does that sport?" I guess your asking what motor? That one is a factory '69 440/auto 'cuda package notchback with 67xx original miles, NOM or trans.....Drag car from day 1. All original metal except fender well header patches with paint re-shot in '88-'89 (car not taken apart).
How about some pics of your EL5. Auto or 4spd?
If you want to post fender tag pic, i or others will decode for you.
