As far as the carb goes I would probably go with a Holley 1050. But my concern on this combo is that it looks like it has a little too much cam for a 10.5 compression motor. With a cam that big, your dynamic or running compression is going to be from 7.5 to about 8 to 1. This depends on when your intake valve closes. JMO

I own a 1050 Ultra and it is very coinsistant on a 496 BBC bracket engine. If you are using it on the street I would consider having a carb custom built to get it right for you. Pro Systems would be my choice. I have an old Pro Systems 1050 also and it is just as good as the Ultra, just not as pretty.
