LT1 Dyno Archive
I did those numbers before the PCM was tuned / no cut-out / stock internals
I hoping with the PCM tuned now and Electronic cut-out I can do 330 ish HP and 350 ish TQ.
On the old numbers (323 HP / 343 TQ) the car managed 12.61 @ 109 mph
with a 1.8X 60ft.
I'm hoping with the pcm tune & cut-out the car can go 12.30's @ 111 MPH
Watch out for those stock internal all bolt-on LT1's

my cam was one a 112 lobe but had smaller lift numbers. Keep us updated. For instance if you had a baseline and then you added something let everyone here know what the gain was.
If you didnt dyno but you have track differences please post your ET with your MPH since the MPH shows horsepower better than your ET(less variables)

made 370/433 on speed inc's dyno after intmd8 tuned it. passed emmissions (with cats on) that same day
so far best pass is a 12.3@112 with a 1.9 60ft and a nasty misfire up top, shooting for 11.8's @114 with some traction now that i figured out the misfire

My normal 60ft is 1.48 to 1.50. The tires could not hold anymore after it was tuned at the track. The tires also killed the mph, because the 26" QTPs made me run out of rpms around the 1000' mark. Just got a set of 28" Mickey DRs, Kooks stepped LTs, K member, A arms, race seat, LW carpet, and an even meaner cam from my boy Joe

best run
14.2@107mph
2.569 60'
Horrible night at the track. Raced cammed ls1 vette, he ran 14.1@107. No traction to be had anywhere. Next time i go ill be running slicks and a 12 bolt
Oh yeah, definately could have squeezed mroe mph out of it, that was shifting around 6000rpm, should spin it to 6700. And if i could get the 60' down to a 2.0 or better, id have some respectable times.
