Awesome build Brent what fuel did it need ?

[blykins]

93 octane.

Hey Brent was there a difference with or without the spacer. Did you run it with the dominator or is it just for photos

There was a pretty bad A/F ratio difference between sides without the spacer, so I put one on after the first pull and it straightened them out.  So all the pulls were ran with a 2" Super Sucker.

I ran it with both carburetors.  It made 538 hp with the Q-750 and 540 with the 1050 Dominator. 

[Stangman]

Just curious as to why the A/f difference from side to side, and that 750 really performed huh.
Were they both right out of the box. 

[blykins]

It's not abnormal to see an A/F ratio difference between sides and it could be that my plenum divider caused a little of it.   Spacer straightened it out though.

The Q-750 took some HSAB and jet work to get it there but I didn't turn a screw on the Dominator.  To be honest though, throwing the Dominator on was just something we did at the last minute for giggles.  Sometimes you don't know what something will do until you try.

Thanks Brent great job
