Hey guys, been awhile since last time I've been on here...
Im FINALLY about to have my car paid off and im trying to do some research on building a reliable engine for twin turbos, my goal is 800 rwhp...
So far Ive found a 4.6L block im going to pull out of an wrecked F-150 but im trying to decide on if I should get a stroker kit for it or if I should keep the displacement stock...
Any suggestions will be GREATLY appreciated!!!

Oh and if this is a repost of anything, im sorry, just point me in the right direction...

Keeping the stock square bore would be ideal. You should be able to spin 8k+ rpm with the right valve train. Also because the engine is small displacement, twin 57's would probably be your best bet, and keep the a/r around .6-.7. and certainly not more than .96. Ball bearing is a worth while upgrade from a spool stand point

Yeah I was thinking the same thing with the displacement until I came across this article

But you do have a good point u can turn more RPMs keeping it stock displacement...

Which they used a crazy looking intake manifold (that I want to build but cant figure out the dimensions *NEED SOME HELP*)

no one else has any input?

I've read that before. A tuner by my installed an HP kit before, he said it was junk. He suggested going single instead of twins, but that's up to you. I wouldn't do a stroker kit, most people on here with one will probably tell you they wouldn't do it again. The mod motors have a pretty long stroke as it is. I would consider boring it over .020" though. It has to do with unshrouding the valves or something like that, you'd have to ask somebody with a bit more expertise in internals than me for that, but that would be the way to go over a stroker.
