Message: [QUOTE="tbsimmons, post: 732114, member: 2026"] I just glanced through the toughest climbs. I agree with some because they are the ones I have been over, but I have been over some that would demolish the ones posted. Take 46 between I-5 and 101. Take 166 from I-5 to 101. Take 101 between 46 and 166. All these are in the summer. 46 is steep dont know the percent. 166 is 7% after a pretty long stretch of 4%. Both can be in the high 90's to low 100's in the summer. Last time over 166 it was above 90 degrees at 10 in the morning. 166 is known in my area as the tranny killer. Which i think all the ones above are harder than the Grapevine. But you are right the 6.4 tuned and deleted is towing machine. [/QUOTE]
