My Clay Smith cam

Hi Guys,

Need a little input from all you hotrodders. I have a new Clay Smith cam my friend gave me. I will be rebuilding my SBC 400. I want to know what kind of buildup I would need to do to use this cam. Here are the specs.
318 degrees advertised duration , 276 degrees at .050 - 555 lift and ground on a 108 lobe centerline. I will be using this motor in my 2002 Chevy S10. It's backhalved and will be used for street and strip. Mostly strip. Have at it!!!!!
Thanks in advance.

Thom

That is a really big cam. You will need a lot of compression, gears, stall, intake, carb, head, and exhaust. Not sure you could drive that on the street.

13:1 cr min, 4.56 gears and a 4500 stall, 1-3/4 headers and 3 inch exhaust, 215cc head, victor jr intake with a 950cfm carb.

what kind of buildup...SBC 400...will be used for street and strip. Mostly strip...
Block? What are you going to use for internals? Any ideas on the stroke you might want to use? Big deal too, how much in the budget? What head choice??? 23* or other?

I had an idea to use someWorld Motown Aluminum 23° Cylinder Heads
Quote:
World Products introduces two great new cylinder heads for small block Chevy applications. First is the Motown 23° with 215cc intake runners. This Vortec-style head combines high velocity ports with a quick-burn style combustion chamber. This is perfect head for serious street performance. For larger displacement small blocks, as well as highly modified engines, World’s new 235cc intake Motown head is the answer. With huge 2.100” intake and 1.625” exhaust valves, coupled up with highly efficient port designs and Right Cast® technology, these heads flow incredibly well. The screw-in rocker arm studs are installed at 23° --the same angle as the valves. This assures optimum valve train geometry throughout the rocker arm arc. Offset rocker arms are required in conjunction with longer-than-stock valves to maintain the correct geometry.(+Technical Specifications)
in the 235 runner size for a 400 based build. Not a race motor, but a real thumper. I don't know anybody who has run these, so I could guinea pig myself out on them. You would probably be best off with a set of AFR Heads. There are some other awesome heads out there, depending onyour goals, how much your sled weighs/combo, how much head you'll need. What trans/converter, gear,? 4 link, slide a link, or type rear set-up? Slick, street radial, size?? Does it/will it hook? Give some more specifics on the rest of your combo. You're going to build this motor because this is the cam you have? If so, maybe sell that cam and figure out exactly what you'd like the mill to do for you ET wise. You can make 700+ with a stroker very easy, but there are limits if using a stock block. Have you thought about destroking?
