273 cam general driver/MPG/lowend ?

if you read my other post i described it.it was in a 3/4 ton chevy truck with a stock 350 and TH 350 auto trans.it had a slight chop when cold but was pretty stock sounding once it warmed up.the only power adders it had were headers and an and dual exhaust.i imagine it would have a slight lope in a 273.if you call isky they have great customer service and will grind you a custom cam for your application.if you were concerned with the idle quality or the 256/62 you could have it cut on a 112 lsa instead of 110.
