Here's the problem..... By Royce - 05/17/2004 9:12:42 PM; IP 4.224.87.216 The 450 CFM carbs have Generic Motors type throttle arms. The linkage holes are further away from the throttle shaft, so the geometry is screwed for using the factory style progressive linkage. You might be able to use one of the kits from Lokar more effectively. I believe Edelbrock also offers something. The factory carbs (BJ - BK) are rated 600CFM apiece in single 4V configuration. They work a lot better and are worth the slightly higher cost due to zero need to modify them and the tuning will be close to spot - on right out of the box. Royce
