Default Fastest Stock CI LS1?
Hey guys i did a search but did not find what i was looking for, Who has the fastest Stock CI record in an F-body? By stock CI i mean LS1 346-347. I know Peck has been 9.30s on a stock short block, but i did not know if any one had been faster on a forged bottom end?
Thanks Ricky

Harlan's car was a beast that 8.1 run was ahead of time...
I can't believe its been over 4 years now maybe more I can't wait to see the new setup of that car.

Here is an old video

I went 8.90 with stock block, crank, ls6 intake and hydraulic cam. Think Paul with the twin turbo Z06 went mid/low 8s as well with a 347.

Seriously, tune and fuel used is the answer.
