Hi, i have a 1973 maverick with a 351windsor, and will be running it mostly street with days at the drag strip when i can. I have no idea where to go with gear setup. i am trying to get the best of both worlds high and low end. if anyone has any ideas they would be helpful. thanks in advance
That 3.89 is a great gear,& they last a long time if set up properly.Run the math on it & any gear that ends up w/ a # that goes to infinity(.9999999 or .66666) has the best gear pattern & they mesh better so they last longer.
noone asked what tire size you plan to run? stock 8in axle? or replaced with 9 in? if 8in and do decent amound of hiway with no 0/d 3.25 otherwise 3.55 as suggested 9in i'd probably go with a 3.40 o/d or not for traction unit look into the DPI Platnium track(8 or 9)
Just curious why you say that. What does the diameter of the ring gear (8" vs. 9") have to do with what ratio you would run?
the 8in doesnt offer a 3.40 jumps from 3.25 to 3.55 to what a 3.80 9in you have more selection to have a possible happy medium with no o/d a 3.40 with say a 255-60-15 or 275 a 3.40 will do pretty nice on the hiway while having a somewhat fun launch 3.25 will do well enough on launch or hiway weather its a 28in tire or a 25.7 17in low profile but yeah, if you have an o/d its not really going to matter a whole lot, unless you're paranoid about rpm of your driveshaft
If it was me I would get a 9 inch out of a GMV with a 2.47 gears and install an old school performance wide ratio 4 speed with a deep 1st gear. 4th gear would act as an overdrive.
UMM...........you're wrong here. The 8" that my 77 had when I bought it had 3.40's. It's now got a 9" with 3.50's.
Motive gear has a 3.40 8" gear set. I think is one of the more expensive ratios for an 8", though. http://www.provenforce.com/rear_end/8.0_ford_ring_pinion.html
sorry it takes me awhile to get back on the computer. it has an 8" now but i planned on getting a lincoln 9" posi to put under it. dont know the size of tire yet. as far as overdrive goes i think that is out of the question with my b&m racing shifter? also have been looking for v8 motor mount if anyone has any good ideas? thanks for the help so far and again sorry it takes me awhile to reply.
You need to make some decisions before anyone can help you, otherwise it's just a crap shoot. What is done to the engine? Decide on what tires you want to run first. Then decide if your daily driving will be mostly highway or city street. Then decide on what percentage of time will be street time vs track time. What RPM are you comfortable with on the highway? Do you plan this gear in your current 8" or the future 9"? Until you make some firm decisions, there is no way to really give an intelligent answer in my opinion. SPark
dpi platinum track or Strange Engineering S-Trac if you plan to get a 9in built.. best multi pupose unit as it locks as good as a locker, but street friendly like a posi
