Here's the dude's PM; I don't know the guy so I'm not gonna bring up a name.

if youre thinking of building a 20r/22r hybrid or even any 20r or 22r, avoid engnbldr!  I used to buy a lot of engine parts from him, but I quickly learned that he provides crappy parts in a flashy box.  I have seen countless failures in these motors from ENGNBLDR's parts. you need to use JAPAN made parts and NOTHING else.  no USA bull crap parts.  Its always best to use FACTORY parts, but anything made in japan will work great.  trust me on this one, I have learned the hard way many times over and so have a lot of people I know.  basically...you get what you pay for.  engnbldr has inexpensive parts for a reason.  Definatley dont use his cams either.  He only offers 2 different cam profiles...and either one doesnt get you anywhere.  Dont use engnbldrs valves either.   Their parts work, but they dont last AT ALL.  Using their parts is asking for failure. 

if youre gonna build that hybrid motor, I can give you very detailed information on what the best parts are to use (for YOUR truck) and HOW to actually set up the entire 20r/22r motor.  its not as easy as it sounds.  theres a lot of little tricks and a lot of parts that ARE NOT interchangable.  theres also many many little tweaks you can do here and there to get more power out of these motors.  I have a wealth of information about these motors that im willing to share with anyone who can use the help.  dont let the complications of this hybrid motor scare you away from doing it though.  its totally worth it!!!!!!
