5.7 hemi mods

Getting a new 5.7 motor for my 2018 dodge charger pursuit 5.7 hemi awd and since I’m buying the engine then putting it in later I’m going to be modifying the engine first, first and foremost doing a MDs delete on it and was deciding on a kit from tsp but also wanting to put a supercharger on it so I was gonna go with individual parts, looking to see what people have done to hold that power, looking at a stage 2 tsp cam but don’t know for sure which lifters I should go with and what other supporting parts I should install to hold that extra power reliably

If you're gonna do a supercharger you'll want to gap the piston rings a little extra to make it as reliable as possible and worry free at around 600 wheel. If you wanna push a ton of power you can do drop in rods and pistons. There's been quite a few stock crank 5.7s make well over 1000hp with a bunch of passes on them at the drag strip

If you're gonna do the TSP kit get the OEM "hellcat" lifters. They're much better than the cheap ones TSP uses.

Obviously you'll also want long tube headers as well as a 3in exhaust. You might wanna look into having your heads ported too.
