I think they are asking if you know your compression ratio. If you or you engine guy cc'd the heads and you know what head gasket you are using, we can get close.

-----Hard to determine without the compression ratio as every point is a bunch-o-ponies.

I thinking around 9:5.1 or close to that-It was built to run on "pumpgas" & with a Nice Shot Of Nitrous Oxide, But I havent got that FAR yet- its a Fresh Motor And So far On the street Its Torquey...But I just wanted to see What kind Of HP She's got...

I'm sure it's a stong runner. You could say it's a 500 hp enigne and be safe.
I personally feel whp is the best way to speak about what a car's engine is producing. How about doing it in true New Yorker style and have it dyno tuned? For now, got a video of that thing? I'mm sure it sounds great with the cam! |
