Pls be kind I'm new to performance and building a truck from ground up but I've been working on my own vehicles since I owned my first car at 16 and I've learned a lot over the yrs (now 42) doing my own work, but I dont know crap about performance parts or what's what and how to decide what to go with. I'm rebuilding a 2000 dodge dakota 5.9L R/T super bee, the body and frame is shot so I'm pulling the 5.9 motor, tranny, rear end, PCM, ECU and wiring harness (donor truck is complete)and once done I'm putting it all that into my 2002 dakota with an wore out 3.9 but a mint frame and body. Ive always dreamed about having a 2nd gen dakota lowered with a 5.9L with about 300-350 HP. But before I put everything from the 5.9 into my 02 I want to rebuild the motor (has 245,000km) and I've seem some rebuild kits that includes pistons, piston rings, all new bearings, frost plugs, timing chain and so on but when it comes to rebuilding a motor and adding more HP, I'm completely lost when it comes to performance parts and what to go with. It would greatly appreciated if some of you more experienced ppl in building up the 5.9L motor could give me some advice and tips on what to be looking at and where to look, I wanna expand my knowledge and build this truck from ground up on my own. My build limit is $3000 for motor, tranny and rear end. I know that's a low budget (in my eyes) for what I'd like to do but I'm in no rush so if it's a little over my budget it will just take longer lol. I'd greatly appreciate it if one of you fine mopar lovers can help me figure out what parts I should be looking at replacing and what to replace it with. I have a good idea what parts to replace just not what to replace them with. I think I've covered my plan well and all the details I know or have, if you have any questions to help me achieve my goal then pls ask away and I ty in advance for any and all tips
