Help me new to 12 valve!!
So I have been over heating the search option on my computer to find nothing but the same results... But in diff. Format !! I'm looking to make 600-650hp to tow my crawler and drive it daily... I know guys please hang in there with me..
My story is this the rig has well had 238k on the motor as about a week ago the KDP decided to kill and in the result of that I have a broken cam gear and cam, timing cover and case, and well 6 bent exh valves and 6 exh push rods... Yeah can y'all fill me in how this happens? I know kdp but broken cam and bent valves and such.. Needless to say I pulled the motor and it's off to the machine shop getting a .20 over and marine pistons I just need help with the HP part of the help
So PLEASE let the best ones throw your ideas out there!!!!! I'm willing to listen and learn
This is what I have so far to bolt on and install
AIR: 66-71-14 htt gated, afe magnum intake, custom built "by me" intake manifold and plate, maybe equal length header? 60# springs ,
Fuel : new era 200hp injectors I think 6x..? , 093 lines, full cut DV, high flow holders, 4kgsk, p7100 at 22* , 100 plate , afc spring kit, air dog??
Exh:5" TB
Motor overhaul with .20 over bore marine fly cut coated pistons, balanced rotating assembly , polished crank, hemilton street cam, billet push tubes, studs, ringed, marine HG..

Diesel Bomber
Back on the subject of the KDP, I know you had asked how it could cause such destruction. Here are the three options of scenarios that can happen when the KDP comes out, stolen from a post by Whit 
Option number one: you get extremely lucky and the pin falls through the maze of cam, crank, and injection-pump gears and lands harmlessly in the oil pan or on the bottom of the gear housing-and nothing happens. Total cost for repairs: $0.
Option number two: the pin falls, and it comes in contact with the cam gear and smashes into the gear housing on the front of your engine. When this happens, it is steel versus aluminum-and steel wins out. The housing will crack open or lose a big chunk right where the dowel pin was forced into the housing. If this happens, you'll wake up the next morning and notice the Exxon Valdez in your driveway. Your total repair bill, including labor, will be approximately $1,000.
Option number three is the killer: the pin falls and munches up the cam gear or breaks it off completely. The valves will then smack into the pistons, creating a junkyard in your combustion chambers. Scraping metal doesn't work nearly as well as #2 diesel, and this can take out your heads, valves, and pistons-and possibly your engine block, making it impossible to overbore and rebuild. If this happens, there are almost no parts you can salvage, and your only option is to either to sell the truck for parts or pick up a new engine to the tune of at least a few thousands bucks. When option number three happens, you'll be left stranded on the side of the road.
