I just did a TR224/114 lsa a few weeks ago. I haven't got it tuned yet, but it makes good power by SOTP. It does sound a bit like I have a few sewing machines under the hood sometimes. It is very driveable and doesn't die too much without a tune (I'm getting one soon). I put the 918's, titanium ret., hardened push rods, double roller chain, and LS6 oil pump in with it for extra insurance. It will pass emissions too, if they sniff. I'm more worried about the visual inspection now, with the after market exhaust. I don't think I can get away with anyone not knowing that I have a cam right now. Maybe the tune will smooth things out.
