V6 3791 cc | 231.3 cu in. | 3.8 L. 235 BHP (172.96 KW) @ 4400 RPM 330 Ft-Lbs (447 NM) @ 2800 RPM Bore : 3.8 in | 97 mm. Stroke : 3.4 in | 86 mm. Yes to hard to believe. Hope the spec chart helped.


Yeah, no. 9


Yeah no. 9,500 is in VTEC and RX8 territory. Not Buick.


Not sure that I would take the advice of a Pep Boys store associate or parts guy for something like this...LOL! They give decent advice on SOME auto parts. To think a Buick can red line THAT high is insanity, IMO.
