Last time on a chassis dyno with my old heads cam and unlocked 4l80E I made 469rwhp on 91 octane and 28* timing.

Today with 20* timing I made a pull with 91 and laid down 511rwhp.

With E48 I turned timing up to 28* peak tq and 26* peak hp (what it liked, tried a bit more with no gains), made 546rwhp.

Drained the tank again and put E85 in. Did not gain anything on E85 compared to E48.

Dyno sheet coming.

Combo:
418ci
13-1
PRC 237 heads
254/260 .62x/.63x hyd
Super Vic intake
Dominator TB
1 3/4 stepped to 1 7/8 edelbrock headers (think they are holding me back)
Dual electric cutouts
Power glide with 5,200 rpm verter
