Sure you didn’t get a Chinese stamping?
Sometimes trying to help is like .For those that aren't aware of what Midlife Crises is referring to concerning the cam followers here is a picture of the new Ford redesign beside the original....the new design is the bottom one in this picture:

I must admit, this cam thing has gotten me uncharacteristically undecided and second guessing myself.
It will be a B326 with a DOB Gen3 TVS kit. I want to be at 700+ RWHP on 93 and approaching 800 on E85. Not interested in going over 800RWHP, as I want to stick with the returnless fuel system for now. This will be a fun street car that I drive on backroads, around town on a Saturday night, and to an occasional car show. No racing, so "peak" HP is not worth giving up driveability.
The influx of data:
I'm about to say "F it!" and just tell Brenspeed to stick with what they say works (450 and limiters).
- Everyone, including those on this thread, DOB and Lito, say lock the cams . . . except the people actually making the motor (Brenspeed). They say they have not seen limiters or the VVT fail under their current setup. But, they will lock it if thats what I want.
- Brenspeed recommends the 127450 cam (with comp cam limiters) for a nice power/drivability compromise.
- But, Brenspeed has not worked with their engine and this particular blower setup. Lito and DOB both say that, because the Gen3 will have so much torque, its worth the small loss down low to lock them out and ensure safety/durability.
- But Lito says the 127450 is not ideal and recommends a custom grind. I'm not interested in getting into custom grinds. If not custom, he says go to the 127350.
- DOB hates the 127350 and has had nothing but disappointment with it when used -- and especially if locked out.
- Comp cam recommended the 127350 with a blown setup, versus the 450. Says the 350s don't even need limiters.
- DOB says either stick with the stock cam or go big with the 127550.
- Many people, including Lito, say the 550 causes drivability compromises.
I never go bacwards with technology.
That's good to know.....…...He said they used to lock down the cams years ago because of issues, especially with the bigger 127550s. But, since the revision to the followers, they have not had to. He said that Ford did, indeed, change the design based on feedback even though the 4.6 was out of production. And, he reiterated that they were design changes based on lessons learned from the Coyote.
