Don't feel bad about asking these questions Npost. When I first joined I had owned a an Iroc, and you can pretty much swap any old engine in there rather cheaply. However, Chrysler makes it hard and EXPENSIVE to do the same. Not to mention performance parts costs for our trucks.
When I first joined, you were very limited in performance upgrades, and the ones that existed were very expensive. You pretty much needed to do a cam swap to get any noticeable increase.
Now, there are more parts, and they are relatively popular so you are not paying for their weight in gold like in the early-mid 2000s!!
