Well i put the hot cam in my truck and i like it alot its sounds more then what it realy it is but i have notice big diffrence in it from the stock alot more pulling power sense i pull a lot with my truck thats a plus for me as far as gas milege i cant say anything there as my heads are ported and polished as far as you can take them and that hurt my mpg. Over all I thinks its a good cam for dd and u little more out of truck on the performance side to.
