Let me add another thing - my whole argument against CIS (and Motronic too) is that they are throttle-body induction systems. In order to run a more aggressive cam, you need to have individual throttle boddies, like on the MFI system or Weber carbs.

However, I'm not a huge fan of simply bolting carburetors onto a CIS engine. You will get poor gas mileage, an emissions nightmare, and decreased performance, overall. You may get a bit better throttle response, but it's at a high price. The only time I really advocate ditching the CIS system and bolting on carburetors is if you're going to swap out your camshafts.
