Dyno'ed my car last night

Mostly just wanted a baseline

I dont really have a means to scan and post my graph, soo...

Temp was 93 degrees at 42% humidity

280.9 rwhp
305.6 rwtq

That was with the cutout open and the mods in the sig...i was expecting more like 265 hp and 290 tq.

Above about 4900-5000 rpm, the graph gets REALLY spikey, and I know thats because my plugs are trashed (at 46k miles and never changed them)

Up until about 4300rpm, my tq curve was FLAT as a board, I mean REALLY flat...dyno operator said hes never seen one like it...good 'ole LT1, eh?

Pretty good i think for basically nothing but a Cutout and CAI and really messed up plugs.

With the cutout closed it made 267.8 rwhp and 304.3 rwtq at peak, with about a 3-4 hp difference all the way along the curve. I suspect this difference will grow once I get headers

What do you guys think?

never been to the track...i want to go soon to see what i can pull off

After headers/full exhaust and newer better plugs/wires, I think I can hit around 300 rwhp

We'll see...

I think you'll probably be a tad over 300rwhp. You have a pretty strong car.
