C-3, 1970 Corvette 454 cam specifications

[D S.]

Hello. I am having my 454CI/390HP engine rebuilt. I am going with a stock standard rebuild, no frills. What camshaft is recommended for this and where do I get one?

Thanks,
Scott

You can get a Crane-manufactured reproduction of the original camshaft in a kit which includes lifters from GM dealers under GM #12364055. GM list price for the complete kit is $177.13 which makes it a very good value, especially if you buy it for less than this price from discounting GM dealers.

If you are doing a stock rebuild, the above is what I would recommend doing. Whether, or not, there might be "better" cams depends upon what you're after. If a stock rebuild is what you want, the above is what you need.

The 1970 LS-5 camshaft, which was also used in many other big block applications over the 1966-72 period, made more torque than any other engine ever installed in PRODUCTION in a Chevrolet-branded car, either before or since.

The above-referenced camshaft may or may not have the rear camshaft journal groove required only for 65-66 big block applications. If it does, then, according to Chevrolet, you need to modify the camshaft rear bearing by soldering shut the hole and redrilling to .060".
