Bore the 3.1 to a 3.2???

[90TGP]

Would the TGP motor see any gains boring it from a 3.1 to a 3.2? I know that the Cavalier guys do it [sometimes].

Sure you would see some gain.  This bore would add approximately 6 cu. in. displacement.  Since this engine in stock form puts out more than one
HP per cube,  I would approximate about a 7-8 HP gain in stock form,  and expedential gains with Mods.
