Only 460hp

Compression is what stands out to me as holding back some hp. For a street car it sounds like a very nice engine. Everyone always wants more hp, but how often in a street car do you use all the hp anyways?
Yeah that's the first thing I'm addressing. Brian Haflinger from IMM engines commented I could raise compression to 10.2. I'm gonna take his advise. Trying to find flat top pistons with the correct cc's is an issue. Trying to avoid a running another dish.
