Final track pack thread
#61
When I had my Track Pack in for the Timing Cover oil leak, I also asked the Master Tech who worked on my vehicle to listen to the clutch. I had a noticeable noise from the clutch (Not the Pedal) when letting the clutch out. He thought the noise was not an issue and mentioned he thought the Track Pack cars had a different clutch than a standard GT. Anyone else heard of this?
Clutch is the same for all 5.0's, even Boss cars.

The 2013 gt has the same aluminum block as a boss. They do have forged cranks, some kind of coated pistons and rods the reason you get diff part numbers for the boss vs gt is that they are diff. The gt has forged crank and hyp pistons and looks like standard rod. The boss has a BALANCED forged crank, matched by the BALANCED piston and rod set. So they are deff diff but the gt did get upgraded in 2013. They also def have no oil squirter at all for the piston. Im a tech at ford and we just took a 2013 apart trying to identify this tick issue. We ordered all new parts and I have a 2011 I blew up on boost that I had the parts laying around still. They are def diff pistons crank and block w no oil squirter. i still dont get why it matters. W out the rods and pistons to match a forged crank it doesnt matter a bit. The crank has never been the weakest link lol! And you cant just throw boss rods and pistons on a gt crank due to the balance. But you can throw mmr rod and piston set on the gt crank and be stronger than the boss and the boss would have to rebalance for the manley rods n pistons. But yea thats whats up w the numbers. This applies to all 2013 gts not just the track pack.

My buddy has a boss that had a problem with it's clutch sticking. They told him they put in an upgrade part that was ordered from ford racing. I'm assuming they did the same for you.

To further throw a wrench into things here... here is some better clarification of the part numbers you have listed, along with actual Ford P/N spacing Con Rods : BR3Z-6200-A vs. CR3Z-6200-A The only difference between these part numbers is the prefix, which just identifies the model year they were released for. B = 2011 C = 2012 The rest of the part numbers being identical, leads me to believe they are actually the same part, even the same "A" suffix. Although this may not necessarily be the case. A regular 5.0 engine assembly could call for the BR3Z part, while the Boss engine assembly could call for the CR3Z part. Crankshafts: BR3Z-6303-C vs. CR3Z-6303-A These part numbers have both different model year and suffix differences. This lends me to believe they are in fact different parts completely. The difference in suffix is really where the difference comes in. In this case, the A suffix looks like it's the forged, and the C suffix looks to be the cast version.

You might enjoy this thread. New coated pistons, different oil control rings eliminating the need for under piston squirters (which also reduced windage) and improved oiling, which apparently resolved the #8 failures in the 11/12:

Any truth to the claim that we have the entire Boss 302 axle, not just the finned cover, 3.73s, and Torsen? I believe the Boss axle tubes have additional welds holding them into the diff housing, and I remember people were twisting axle tubes on stock GTs. I'd like to be able to beat on my car with some sense of security.

Has anyone installed an aftermarket set of headers on a Track Pack car yet? I took a gander underneath the car yesterday preparing to install my Borla long tubes when i noticed the oil cooler plumbing may make things difficult on the drivers side.
