So a few months ago my truck was used in an unnamed tv show (can’t say til it airs) and unfortunately the motor was destroyed. Good news is it was covered, and that’s all I can say about that for now.
I myself actually blew the original motor about a year ago. Some friends and I were in the mountains messing around, I hit some small jumps, enough to dislodge the OEM liner on the drivers side, so when I went through a puddle, water went directly up the intake tube and destroyed the motor. It truely was a perfect storm. So I had the motor replaced, and that second motor was the one destroyed by the show.

That being said, I decided this time to do go all out. I called Livernois. A few months later and a lot of phone calls and emails, my 6.6L 400 cube stroker race motor is finished being built. This is the most powerful Raptor motor they make without a supercharger. Yes some will ask why not a much cheaper LS motor. The main reason is, besides very high end trucks and race vehicles who replace the entire brain, no one really has done it for the average person, and I was not about to be a guinea pig! (Motor specs at bottom)

The motor is going in next week, I am leaving it NA, so we set the compression to 9:5:1 Its being paired with stainless works ceramic coated headers and full 3” exhaust off road pipes, not cats, and 2 magnaflow mufflers. Intake will be an SB intake, BBK throttle body, and a Moroso oil catch can. Also adding Advanced Fiberglass Concepts fenders +2 with liners so I don’t have a repeat of the first motor. As soon as the motor is in it’s getting dyno tuned and properly broken in. As soon as I have pictures of the motor and the install I will update this post as well as the progress and hiccups that I’m sure will happen. As well as the dyno with the HP gains.

It will be interesting to find out how much this puts out without a blower. Most of these have gone into Whipple trucks. And a few twin turbos.

After talking to Livernois and going over the motor and the other add ons, they’re expecting around +100 rwhp

Make sure to post pictures and videos as the build comes along. I plan on purchasing the 6.6 as well.

What are you doing for your transmission? I know a couple of guys that have had the transmission rebuilt/upgraded.

@Truckzor have you did anything on your transmission?

The trans is stock for now until a need arises. I have upgraded the pan to a larger AFE and a larger cooler.

The craftsmanship on these motors look impeccable!

Are you having a shop in Colorado do the install?
I think so too, such attention to detail. I’m having someone I know who’s a motor genius assemble and install it, then it’s going to Rocky Mountain Competitive Research for tune & dyno. And the piston compression is set at 11:5:1 since no boost, typo on original post.

You can check my build thread for all the details of the path I've taken (needs to be updated soon, as I've done a lot of new stuff) but off the top of my head:

I have a Circle D billet torque converter, upgraded clutches from Exedy, 300M intermediate shaft from TCS, larger pan, and larger OEM trans cooler from the Dubai Raptors. Also the PA dipstick.

I don't think OP needs to do anything, though, since he is staying naturally aspirated. Sounds like his truck will be pretty close to 450 RWHP, which is really pretty good considering a Roush stage 1 truck that is otherwise stock will typically only make up to 480 RWHP.
