Highest flowing sbm heads?

Show me some quick W5 times, combo, and tracks the times were made.

I made a bit over 700 HP on 340 inches with W5 heads.

In the car it went 9.30’s-9.40’s at 139ish MPH. And the car had issues.

If I had a virgin set today I could easily make another 30-35 HP over what I had.

Aint not chink head doing that.
