Yeah I don't know why people are buying stroker kits for 5.7s, they cost as much as a hellcat short block brand new from the dealer ready to drop in. All the extra money machining and time assembling for another 200 CC and your local machine shop probably ain't as acurate as the factory? It also seems I heard the 6.4 truck engine was all forged guts, it should be a good turbo build also around the same price.
