Critique my mismatched Teen Build.

Thanks all.
All comments, advice and criticism much appreciated. As I said, first build so am still learning.

It looks like my HP estimate figure seems to be around the mark then.. that's great.
So if i was to move up to an Xe268 hydraulic or equivalent, there would be perhaps another 20-25 HP available to me maybe. Similar torque though?

At this level, is there any gain whatsoever by switching to a solid cam for what is really a Street Car? Personal preference only perhaps?
I'm guessing any gains would be at the very upper end of the Rpm range only?


Cheers,
Teedog
