What kind of an LT1 vette puts out 275 rwhp stock? I thought that even the LT4 only put out 260 stock, or is that one guy's signature wrong?

Which ain't 275 rwhp.

For my C5, it ran close to $100/hp for bolt-ons, and I expect the C4 to be about half that. I look at it this way- I buy the best thing I can afford. If it means I have to save a little while longer to buy real headers, so be it. Obviously things like cams and spray give you a lot more power for the cost.

Most LT1 manuals I've seen dyno about 265-275rwhp - the auto around 245-255rwhp.

The LT4 dyno's around 295-305rwhp
