Default ProSystems Dominator

For sale: ProSystems Dominator. It was just rebuilt by ProSystems in December 2021. I had Patrick upgrade everything possible. It has all of the XC program upgrades. It was built for my 484” IA2 Highport motor and it ran great! Only reason I’m selling is because I’ve switched to EFI in preparation for turbos.

“The XC program includes VENOM Blocks, our Red CNC Billet double step boosters, our adjustable air bleed configuration (that actually responds to tuning), drag float, jet extensions, live-tested, wet-flowed with a complete wet-flow portfolio that shows all of the hi to low jetting parameters, for easy jet selection (if any is needed we're usually dead-on or within 2 jet sizes).”

$800 obo shipped lower 48 states

I emailed Patrick and he said it flows 1086 cfm. I forgot to ask about the venturis. My digital gauge shows it has 2” (1.998) bores measured front the bottom.

I drove it on the street a bit and had no issues. It didn’t load up and ran clean.

Yes, it drove great and was very responsive. It didn’t load up and it started and idled great. I was very happy with it. I told Patrick I’d be street driving it when I had him rebuild it so it’s possible he adjusted a few things.

What might you need that you would trade for? I would like to try another carb on my 461 Pontiac.

I’d be open to it but I just finished a huge round of upgrades and I can’t think of anything left that I need. Maybe a transbrake for a T400? I can’t think of much else.
