Re: Can you help identify this Aluminum 427 engine
074 heads are the only factory correct ZL1 heads...there is nothing wrong with those heads on this engine...yes, that is the correct advertised compression...
ZL1 = 427 cu in and L89 = 396 cu in....same stroke different bore, thus different pistons...
Nathan...do you know how long that car has had the "stinger" hood on it?...
