Great video, I got a 2013 Laguna Seca Boss 302 version and love. She is a garage queen, lol.

I have been looking for this video. Thanks for doing it and posting details . Can’t wait to see it come together

[@kriswest4808]

Super happy your working on the mustangs! That crank looks great! Can't wait for the next video.

[@paultavres9830]

During crank polishing did you block off the oil rifling or clean out the rifling

[@ebutuoyebutouy]

Awesome. Thnx for sharing. CDI still ok?

[@ALLMUSCLEUSA]

Yes it is. That car is me and the wife's daily driver. 40 mpg you can't beat it.

[@Dudebrotheguy]

This might be a silly question but is the road runner direct injection ?

[@Marcus2750-u1t]

Its not…. 2012/13…….. no

[@maximusvonce1381]

What was wrong with original boss motor from ford. Why are you rebuilding it.

[@ALLMUSCLEUSA]

The rod bearings went bad and took out the crankshaft. I bought a 22k mile replacement engine for the car. Then I decided to rebuild the original engine.

Boss Roadrunner is way better than a 15 Coyote, and even better than a Gen 3 Coyote. I know cause i have a soon to be Authentic True Boss Roadrunner in my 11 5.0 with gen 3r and mild pulley for 800wheel e85 daily driver. Boss Has forged Mahle pistons, high tension valve springs for 8k rpm, bigger cams, forged rods, way better heads with bigger valves, roller follwers, lash adjusters etc....Boss heads have thicker casting and added copper to strengthen heads, fully ported CNC job, Fully balanced rotating assembly, unlike any coyote. Better head studds, gaskets,,everything. Even a Gen 3 coyote not as good cause Gen 3 coyote still has cast pistons. Boss also has Sodium filled exhaust valves for better cooling. Block has rerouted coolant passages. Anyone who says Boss and Gen 2 or 3 are almost same is a fcking knuckle dragging meathead. Boss Roadrunner is designed for high rpm endurance racing. Its fcking sick motor. Glad i found one for my soon to be 800wheel 11 5.0 daily driver e85.

[@ALLMUSCLEUSA]

Everything is correct. Except the rods are not forged. Only the Pistons are. I have a complete set of the original Mahle pistons with rod combo that I might sell. We used Manley rods and pistons with lower compression ratio for this build so we can add supercharger.

[@maximusvonce1381]

@@ALLMUSCLEUSA Ford says the rods are forged. I can show you link. No point in using a forged piston without a forged rod

[@maximusvonce1381]

@@ALLMUSCLEUSA I am putting in manley rods anyways. Keeping stock forged Mahle pistons.

[@ALLMUSCLEUSA]

@@maximusvonce1381 Yes post that link. I'd like to see what is said about the rods. Good choice for upgrading the rods. You should upgrade the pistons too. Lower the compression ratio if you're going to add boost. Those pistons are meant for n/a motors.

[@maximusvonce1381]

@@ALLMUSCLEUSA Why upgrade a Forged Mahle piston. The forged pistons are boost friendly.
