When I saw this build thread I thought of agjake11 (jake) right away. This thing is going to rip!
Full build thread here

Hey guys...before the flaming starts...i just want you to know i am excited about doing this conversion. and i fully understand that putting an ls1 in a 99 f-150 is sorta sack-religious..with that being said... I DONT CARE...and i came here for help!
SO FLAME AWAY! i love my truck and i hope this motor is as amazing as everyone says it is...

So i am a newbie to the ls1, but i have done some conversions such as a 3.8 GN motor in a toyota and a couple others.

So i have a 99 ford f150 extra cab Long travel pre-runner and her name is Sally!
It started off looking like this...

then i bought some suspension for it..

took the bed off and did some other mods..

and now this is what it looks like..

and last but not least...the new motor that is going to go into it!

this build is solely for offroading/prerunning. I like simple and yet effective vehicles. There will be no turbo/blower setup on this motor.
i want a naturally assperated 400hp motor or so...to put in my truck. I heard the LS1 is a great starter.
So things i was hoping to get help with...
simplest way to get to 400hp and what tranny i should use..and any other help i need along the way would be greatly appreciated!
