Hi.....the F-code engine with supercharger: what state of tune was it in? For example, was it like the 245-horse engine but with a supercharger?
What about the 2x4 engine? Was that the same as the 245-horse engine aside of carburetion?
What about the heads?
And, lastly, what was different about the E-Bird upgrade to 285 horses? Was it just compression or was there more?
Thank you!
