Maybe….
Not seeing it.
I love manual transmissions. Knowing your first gear ratio is a really good thing to know. I do have one thing though, I’d like to say, the 3.55’s will limit camshaft size or you’ll be a dog out of the hole and a screaming top end that will take a long time to get to.
In the other post, you mention a cam duration of 243. IDK the overlap amount…. But a duration like that would (strictly IMO) of at least 3.91 with small tires (smaller than 27 inches) and 4.10’s as a min with a taller tire like at 28 inches.
(I’d do 4.30’s on a 28” tire.)
Oh! I know…. I know…. Been there done that still doing it!
So tell us here… what’s “Fast” for you and are you more so in the street or track?
