cam swap
ok since the LT1 cam swap seems a fairly popular choice for TBI, i grabbed one on ebay awhile back for cheap and its been waiting around since
so I was playing with desktop dyno 2000, and i know its not accurate to any degree but I hear its nice to get an idea of what a cam swap might do for you etc.. and I figure im doing something wrong... but I cant get it to tell me that its a good idea
i mean +2hp and a noticable loss of off idle torque doesnt sound like a good idea
what am i doing wrong here? ;p
anyone actually dyno before and after the cam swap? (i mean the cam swap alone, not a whole buncha mods)

Are you sure your're putting in the correct numbers for the stock cam? It's something like 187deg at .050
