HEY GUYS,IM BACK BUILDING ANOTER ENGINE AND NEED SOME INPUT.THE LAST TIME YOU ALL HELPED ME GREATLY.THIS TIME IM BUILDING A 406.THE BLOCK IS A .030 4OO 4 BOLT,IT HAS .030 FORDGED DISH PISTONS,STOCK CRANK AND RECONED RODS,THE 5.565 RODS,MAGED,SHOTPEENED,RESIZED WITH ARP BOLTS.RHS VORTEC HEADS WITH 1.94/1.50 VALVES.I WAS THINKING ABOUT GOING WITH A COMP CAM 284 EXTREME ENERGY CAM.WHAT DO YOU THINK?? I HAVE A PERFORMER RPM AND A VICTOR JR INTAKE ANY SUGGESTIONS?I HERD ALOT OF NEGITIVE THINGS ABOUT USING THE SHORT ROD.DOES ANYBODY HAVE ANY INFO ON THAT?? I FIGURE SINCE I REWORKED THEM AND PUT ARP BOLTS IN THEM THEY SHOULD BE OK FOR A MAX OF 6000 RPMS.I HAVE A 750 AND 850 HOLLEY DOUBLE PUMPER.THE ENGINE IS GOING IN A 1978 Z/28,TURBO 350,2200 STALL AND 3.55 GEARS. I HOPE TO HEAR FROM YA ALL AGAIN.  THANKS  

I would use a lunati bracketmaster cam kit p#00012LK witch has a .515 lift, the rpm intake, and the 750cfm holley.  

I completely agree with pontiac the victor because it is a single plane intake manifold it will end up hurting you more than helping. you will lose a lot of idle stability.  Like pontiac said the 750 Holley double pumper would be the better of the 2, but I think, if this is going to be a daily driver, that an Edelbrock 750 double pumper would be better. The way the Holley's were made with the float bowls sticking well over the intake manifold causes warping problems. The Edelbrock carburetors don't hang out as close as Holleys do. The cam is one of the few things that is very hard to find a perfect fit for the engine, because there are so many to choose from (hydraulic, mechanical, flat, or roller,) all I can advise you on is get something with a wide lobe separation this will get you better vacuum from idle throughout your rpm range.  

THANKS GUYS.I WILL GO WITH THE LUNATI CAM,RPM INTAKE,AND 750 DOUBLE PUMPER.DO YOU THINK THE CONNECTING RODS ARE OK? THANKS AGAIN  

The rods should be fine but I would keep the RPM'S down around 5800 or less.
