I will have to look at it again now to see if it is a 440 or 340..... The other two are hemi's though...their hoods were open, the 6 pack wasn't. I am going back Monday, and giving him my SRT flag for his man cave. I don't need it....and it belongs with a guy like that... I will be going back to Chevy one day soon...so, it will have a good home...
