Northstar powered car vs Bonneville GXP
Hi, I dont know if this is the right section to post this since its not specific to a model. My question is, what are the differences between a Bonneville GXP and say a Northstar powered Seville of the same vintage? Does the GXP have better/higher flow exhuast than its Cadillac counterpart? Thank you for the info.

Re: Northstar powered car vs Bonneville GXP
I think that the GXP does get better flowing exhaust, but I believe it also gets the 3.71 gear ratio with the 275 hp engine. 3.11's went with the 275 hp engine and 3.71's went with the 300 hp engines in Cadies.
