[QUOTE=mike100;577837]I thought a stock LT1 was less than 260 rwhp (it is only 300 hp crank, right?) maybe you meant LT4.

That's what I was thinking. Might be a bit hard to squeeze 280 RWhp out of a 300 hp engine. I got 259 rwhp out of my LT1 with 145k on it with an A4 so you might expect a little better with a manual.
