Hello,
I am Getting ready to pull out my 3.07 FD because it is getting a little noisy. First of all, I have a rebuilt 455 with a RV cam and headers in a heavy Royale and I pull a 92 Tracker. I have been fairly happy with the 3.07 and I normally cruise between 65 to 75 mph, probably closer to 75 mph.
Has anyone out there replaced their final drives to the 3.21 and been really happy? Or really disappointed? Wished they would of gone with a 3.55?
I have searched past posts and have only found opinions with the 403 engine.
I would think a 3.70 would be overkill for me. I don't pull extra heavy loads or travel the Rockies.
Thanks all!, Scott.
