questions about low 1st gear

[hardtimes]

my cousin only runs a 4.33 gear shifts at 6500 and his converter is 5100. has roller spring perches in the front and also runs a maverick springs and the calvert shocks his wheel stand is only about 1/3 of that one. but he wants his to look like that one. the two combo seems pretty close to the same, except the gear do you think it would make that much of a difference.
