3.5 to 3.69 or vice versa would not be very noticeable for either of you. for you decreasing to 3.5 would give you slightly better gas mileage, maybe 1mpg, your car would accelerate slightly slower. your top speed would technically increase, but you wouldnt be able to find out since you are drag limited. Even 4.08 gears can do over 167mph, how fast do you really need to be able to go? Also, changing final drive does not affect horsepower or torque at all.
Tell your friend to purchase 4.08's for his 350, you should leave your 3.6 alone.

Will this extremely small difference in Final Drive does anyone feel it'll dramatically affect my SRM experience?
Since I'm looking to go FI anyways I figure I could do this swap now to help my buddy and myself for the future.
Any other benefits from a Final Drive swap such like this where it's lowered instead of increased?
**EDIT**
What increases/decreases will I see for below?
MPG
Top MPH
Horsepower
Torque
