Trying to figure out the highest Dyno numbers of a stock bottom ls1 with Stock GM Castings. My car make 448/398 on Serious HP Dyno here in Houston 2 nights ago. It's a Dyno jet. I'm thinking I might be pulling a record here. Here's the specs of the motor:

Stock bottom ls1

Stock 799 heads

Custom grid cam -
23x/24x .62x

Stock fast 90
92mm Nick Williams TB
LS3 Maf
MTI clear lid


1 7/8 headers
3" ypipe
Cutout

3.90 gears

3200 Circle D stall

Built 4l60e

Unlocked converter

Not the same, but for comparison we made 470whp on a mustang dyno cam-only ls6 with stock 243 heads fast 92 and all the bolt ons thru 4.10 gears and an m6 with a drag radial.

This is likely close to 500whp cam-only on a dynojet. But dyno numbers are just that.
We were able to confirm this on the drag strip.

If the track times can back up those dyno numbers I'll be very impressed
