need some input

[Z28 This]

A friend of mine has Motive gear 4.10s sitting around that hes gonna give me and i was thinking about switching out my 3.73s for the 4.10s i have stock heads and cam...and i was wondering would it worth it/ok to switch...i run prostars w/ M/T's with basic bolt ons and upper/lower ported and stuff like that...any input? thanks..

and also how much are the speed cals for 4.10s and what else would i might need to make sure the mph are dead on the money with the gear swap?

i don't think the gain would be worth the cost to have them installed unless your doing them yourself
