BTW, what did Mark find with the differential? With the Trans-Am, he settled on a spool. It's the right answer. The diffs in our cars need to be much tighter. Torsens do not get the job done. The only good thing about them in there's nothing to...
It was that team. The engines were all 5.0 liters, but the fresh head gives a little better top-end seal and that plays nice with a bottom end that has gotten nice and broken in.
Well, I said, "equivalent drivers." I know a lot Corvette and Porsche guys who have faster cars than me. That doesn't mean they get around the track quicker. (see full post)

The general guideline is not to touch them at all when hot, as trying to torque them down to the cold number can stretch the stud, deform the threads, or outright snap the stud due to them now being over-torqued when they return to their cold... (see full post)
That was the trick in FF2000 30 years after he found it. If you put a fresh head on a 500 mile engine, you'd make 1-2 *more* HP than you would when the whole thing was brand new. (see full post)
A totally fascinating thing (which there are tons of in this book) is these fact he discovered that a broken in bottom
end with new heads produces approx 30 more hp. That makes total sense when he describes it and they dyno tested to confirm...

I agree i’m sure it’s work. The car is from AZ and you probably seen it. So what car isn’t a lot of work? i got a brand new mustang and now im thinking about changing tons of stuff on it? It’s and endless cycle. Kinda like Donohue talks about in... (see full post)
Always right before i go out. Not when i come in so usually that’s at least an hour. Or two. Is there a hot and cold torque rating? I know the coated studs at op use less torque all around (see full post)
I think @flyhalf is probably one of the most experienced with the transmission. Even though he moved on to smaller and better things (sequential) lol.May find a lot of what he did in his build thread.
