RustyRatRod's Guide To Hot Rod Bliss

These are my old cam specs. Not a lot of lift but lots of duration and overlap. While I loved the lumpy idle, I was not so thrilled with the low vacuum at idle/off idle and want to tone this build down some for a more streetable ride as was mentioned in the beginning of this thread. I'm not a punk kid anymore and don't foresee racing it, and I've dropped the compression down to a more reasonable 10:1 so the big bumpstick isn't necessarily on the menu anymore.

My first 273 build was a solid 284 duration .450 lift cam. The Direct Connection Manual used to say the biggest cam for a street car was the Street Hemi Grind, about 284 duration and .480 lift. They later updated it, same lift but 280 duration and faster rates. Supposedly better lower end and vacuum with no loss at the top. Your cam is a big cam. I use solid cams in my own cars, typically a Racer Brown or Isky cam. Proven designs and they hold up well. I'm building a 72 340 and I'm going to use a Racer Brown ST2, 218 duration at .050" with .450 lift. If I was going hydraulic I'd just use the 340 cam. Why not start your own thread giving as much information you can and see where it goes?
