Hows this combo sound

Adam, I'd think the 268 would be a good cam. If you are planning to run the Magnum heads, I'd up the compression if you can..They will help put off detonation, and give you more punch...Maybe .5 a pt? as far as a carb, I like the eddy myself, but second choice would be a Thermoquad. I ran a '68 340, with the High Energy 268 cam(no XE then), with a '71 stock intake, and 1.5/8 headers..The thing ran like mad, from idle up. And passed emissions for two years, with some special tweaks.
