So after the many ups and downs ive had with this truck since ive last posted its come to the point to where its getting a 5.3 put in it. Initially i had swapped in another sbc. This time it was a built bottom end 355 with aluminum heads and ive had nothing but issues with the carb and the top end. So ive finnaly decided on putting a 5.3 in the truck. Now i love the sbc plat form but after doing the dod delete on my 2007 5.3 ive since fallen in love with the ls based engines.

The 355 ran great for about 30 minutes and blew a plug out for the cam oil galley, after getting it re-threaded and all sealed up it hasnt ran right since, currently its had a new carb, distributor, plugs+wires, and about everything in the top end re adjusted and it still hasnt ran right since. Thought i was being big brained when everyone told me i was taking a step back with the carb and everything but little did i know those very smart people on here were right. Currently i am tearing down the 5.3 to do gaskets and a cam while ive got it appart, The Btr stage 4 v2 truck cam in my 07 is coming out in favor of a more mild stage 1 or 2 and is going into this 5.3 along with blue ls springs and some other odds and ends.

I spent nearly 3 weeks buried in my laptop trying to put all the info together to do this swap. Although the info is all over the intrawebs, it seemed many questions were still unanswered and part numbers left out when I needed them. I also spent a good amount of time finding the best prices for...
