No it’s an aftermarket engine at that point. A BBC platform, but fully aftermarket, nothing factory about that.
Everybody has an opinion on This ,I feel as long as the architecture of the original design is true to the brand IE: bore space ,deck height ,port layout etc .it is still a brand ..a 598 BBC with a dart block for example is Fairly true to its roots ..you get the idea .. Once you start changing port configuration ,Siamese to symmetrical ,altering deck heights ,just because the timing cover bolts on is it really that brand anymore ..I get a chuckle when I hear people wanting a Hemi head for this or that ..just put a damn Hemi in it then don't reinvent a head that was never offered for your engine .just my 2¢
For the money you have to spend on a 1000hp Buick your not far off an SMX ,proline etc which isn't any brand but is waaaaay better .
