Going with a Gillig
Greetings to all! i can't say how awesome it is that i found this site.....well, alittle back ground first i guess.....i'm coming back from my last deployment in Iraq pretty soon and after taking with my wife, we decided to convert a bus(something i've always wanted to try) and travel the northern states. So, about 3 months ago, i decided on a 1978 Gillig (78 pass.)pusher with a 3208NA connected to a 5 speed spicer...i got it off ebay and drove it back from oregon to southern cali on my R&R break..... it's a blast to drive! but not knowing to much about these buses.....well, i'm just starting the conversion and have alot of questions so any help will be appreciated!
my first problem was that i'm getting about 50mph @2600rpm(fuel mpg was 7)....i've considered going to a 7 speed spicer with the overdrive but that was looking to be about $3000....so digging alittle more, i'm pretty sure now that i have a timken 5.68 rearend...so if a changed the rearend, what should i go to? what kind of cost would i be looking at? any thoughts?
