Thanks and welcome to the site! Certainly the pistons are a great choice. Remember, I couldn't because I limited myself to an "under 500.00" limit. As for the cam, many good choices. Not sure what your gear ratio is, but in a truck you might want something with a 112 LSA, around 212* duration @050. Worst thing is to over cam an engine and have it be lazy from off-idle to 4000 rpm's. I like my cam in my 318, even with stock converter and 2.76's. However, my car weighs 3160 without driver.
