Not really that easy bro nor that inexpensive. Pistons and rods are weak links in our engines. Most piston/rod kits are based on Chevy parts and not "Made" for our engines. Tolerances can be machined to accept Chevy rods, pistons, and even lifters! Problem with these parts is being offset pins in pistons putting additional stress on cylinder walls due to offsets. Use parts designed for the Viper engine!! You also need to figure in bearings, gaskets, seals, etc. while in there may as well add a cam, lifters, valve springs and pushrods. It's very much a dominoe effect but it is common sense to do it all at once while inside. Plan your machine shop to have a few thousand in balancing and blue printing short block.
It's the best investment for your dollar! It's the basis for any build whether Chevy, Dodge, Furd, whatever make. If you plan to spray, boost, or bump compression it should be your first consideration.
There are reasonable amounts of boost or spray with the Correct tune that can lead to many miles of fun, but usually one will keep going for more.....
then Kablooey!!
