Hey buddy just wanted to try to help out alittle and give my advise. I havent posted much on here but just to let you know I have a 04 ecsb 4.8L and just put in our Z+220 cam ( 220-224 dur @.50 .551 .551 lift ) truck makes great upper power also needs min 3000 convertor. But I also did cnc 5.3 heads e-fans header and ory. Still working on tune but loving the power gain will post you a dyno when finished...If you need help or have any questions call or e-mail I have all parts needed in stock....

^^Guys this is a fun truck! Once we get this tune dialed in, the truck will be evn more fun to drive! It does need some convertor (3000 or so should do!), and with your 4.10's it would be killer!
