My Dyno #s for bolt on LT1. Look ok?

I was expecting about 300hp so I was a little off. Do these numbers seem right.

291hp and 319tq.
Mods are: Moroso CAI, 1 3/4 SLP shorties, CSI h20 pump, 3" exhaust and Flowmaster, and timing is bumped 5%(all values).

I also sprayed a 100 shot dry to it and got these:
372hp and 464tq. The a/f ratio went off the chart at 10:1 so it ran a bit rich. I figure getting the a/f right on the bottle will help a lot but it looked good NA at about 13:1 until 5k where it richened to about 12.5.

Thanks for looking and any input is welcomed

It is an m6. I was thinking the torque was a little low on motor but wasn't sure.

If I were you, I would either get rid of the biggest restriction you have now, that pile of crap Flowmaster. It probably hinders you more then helping you. Gets almost no hp value. Just get a cut out, and you will probably hit 300hp and it will only cost you about $40-70.

How restrictive can it be? It has to be better than stock. Are there any mufflers out there that you would recommend? One of the guys at the dyno with me had a cutout on his 305 and it made no hp.
