New motor...... let's talk about the drivetrain!!
Hey all... dropping a Blueprint 400ci in my RS soon. It's rated at 508HP/478 ft-lbs torque.
I was looking at a B&M street/strip 700r4, https://www.holley.com/products/driv...4/parts/117101 .. and I'm also curious about the rear.. should I keep my factory 2.73 or go with something different? I'm primarily looking to cruise and maybe the occasional launch at the traffic light. What are y'all doing for that?
