A 950 or 1000hp will wake it up.

A 1050 dominator is even better but you'll either need to modify or change the intake.

This is provided it's not a 8:1 2.56 geared 7000# Lincoln with a stock convertor.

I am thinking about going to a 1050 also, do the Quick Fuel 1050cfm 4150 carbs work close to a dommy? http://www.summitracing.com/int/parts/qft-rq-1050-an/overview/

I am running a Performer RPM manifold right now. If I go to a Dommy I will need a manifold too.

My experience with the big 4150's has always been that they leave power on the table compared to the dominators. But in some applications a dominator just isn't practical or even alowed by some rules.

Thanks Dave.
It will get some street use, there is a lot of options for the dominator. Lots of studying!!

Carb main body

Post  manofmerc on January 18th 2016, 6:31 am

You shouldn't have a problem using that baseplate to build yourself a 950 .Quickfuel can provide a main body .Just ask them for jetting details .My situation was opposite .I had a 950 main body left over and some metering blocks off an old 830 .Bought a new baseplate and some other parts new carb to use .If you go to Proforms website pull up their 950 carb for jetting and air bleed details .Your engine will love the 950 .I put mine on my 427 merc comet .It ran better than the 750 I had on there .Good luck Doug
