Everyone here has a favorite for their own reasons, but the guy building your motors should have his own combination and after all isn't that why you picked that builder?

Just my opinion.

I also like 18 degree dart for this CI motor. Big Chief, Big Duke and Profilers are also good choices. 705 is a BIG motor!!!

To get 8:1 compression on a 705 you need a total combustion space volume of over 200 cc. Since big chief style heads were designed for 15:1 drag racing engines, they have very small combustion chambers (65-80cc). What piston would you run?
