dual cases or 4.7 in just a single

[lal357]

i'm stuck ya'll on trying to figure out what would give me most benifit the price between the 2 our close so i can throw that out

i have a 80 yota with 20r motor,5spd l52, stock carb, headman heade,r 4.88 gears spooled/aussie on 36's and i am looking for some more low end emmf out of it now i here with duals i can get like 20 different shift combo's vs just the standard 10 (5 hi/5 low)

If I could I would go dual, but my wheelbase is to short. I have 4.7s and wish I could use the stock 2.28 sometimes. I think the duals is a good combo for allround use.

I've been thinking about this myself.So far what I've come up with is this,If you go duals then like Mr Willy said you'll still have the stock ratio for the times when you don't really need to go sssssllllloooooowwww.But then when you need to you can with the other case.
On the other side,with gears you would be stuck with the low ratio at all times,but you can always grab a higher gear in the trannny.
As far as cost,the intial purchase of the adapter is a little cheaper,but then you must modify the drive shafts,cut the floor pan and also you will need another case for the crawl box if you don't have one.With the gears,from what I understand is all you will have to do is make some modifications to the inside of your current case,nothing else to modify that I know of.I think I covered everything if not someelse will correct me.

Dual cases deffinantly.  It will be easier to get 4.7's later after you already have the duals.  Duals will give you more gears to play with, give you a better front driveline angle, and be slower.

Go Duals
I had the 4.7 to begin with and was happy but not as many gear choices as w/ the dual.
Go dual and add the 4.7 later.

If you can afford it, go duals. The prices aren't actually that close to do it properly. With the 4.7 gears, you just take your case apart, modify the inside for the gear set, put it back together, and re-install it. Total cost is $450 plus tax, shipping, and handling. So figure $500 total. For duals you'll be looking at the adapter ($339 plus tax, shipping, and handling), A new crossmember for dual cases (Marlins is $195 plus Tax, S&H, and is about as cheap as you can get for a decent dual case cross member), the driveline work. Most drive shaft shops around here will lengthen a drive shaft for about $100, and shorten one for around $60. If your front susp. requires that you have a long slip front shaft, then you can go square tube (roughly $60 worth in steel). Assuming you have the rear shaft properly done, a square tube front shaft, and a dual case crossmember, then you're looking at right around $780-800 (that's 339+195+60+100=$694x7.75 for california stata tax, and it equals 748+ $15 to ship the adapter, and $25 for the crossmember=$787.) That's assuming adapter shipped seperately from crossmember, and 7.75% california tax. So to go duals, you easily spend an extra $250-300, not including donor T-Case (around $100). The duals are better, because they give you a 5.2 low range and better options for higher gearing. More bang for the buck would be 4.7's

I also vote for duals..Better drive shaft angles,,better gearing options,,,and low range 2wd option is also fun to have..
