Default STOCK LS1 dyno numbers

First of all its a stock LS1/T56 in a '84 Z28..Stock intake, exhaust manifolds, cam, heads, etc..ALL STOCK. the rear is a 3.42 posi setup with 17" wheels all around.

318 rwhp at about 5500 rpm
348 rwtq at about 4100 rpm

I don't know the AFR numbers and the pull was on a mustang dyno.
What do yall think?
The torque was over 300 at 2000 so I was happy with that. But the hp fell off early eh?

Holy **** 318/348 on a mustang dyno in a stock ls1, thats awesome!!! Thats a factory monster right there. Start modding that bitch!!!

The power fell of a bit early most likely because it has an LS1 intake on it, if you get an LS6 intake it will keep pulling up top.
