Article on using a 3.9" crank vs 4" crank
That's an interesting article. I knew most of that however, I didn't know that the 3.9" kept from having to use Oil support rails.
I've always wanted to use a 3.9 and even more preferably, a 3.8" stroke crankshaft. However, I don't know if they exist and I certainly don't want to pay for a custom piece lol.
I'd love a 4" bore 3.8" stroke engine for my Twin Turbo car.
