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 know the cam is to big at the time thats the only cam i had, on the carb should i use a 2 or 3 circuit, and the holley is better than the quick fuel, what size cam would be good, thanks

If it were mine I'd get the Ultra 7320, 2 circuit 1150. Your engine will be much happier.

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.
