Hi Fellas, thanks for the input.
Hey scotty, as you know I sure do value your advice. So I'm gonna expand a little to see if I can change ya mind
I've got the 3.31 jag diff...I would be willing to change to a 3.55 of more some time later If need be. 295/50/15 rear rubber.
I'll be running a 393 Windsor with maybe 450hp and maybe 430 lb.ft...Cam range will be 1800 - 5800...limit the thing to 6000rpm.
Herewith the TKO11 and T56 ratios:
first 2 3 4 5 6
TKO 3.27 1.98 1.34 1.00 .68/.82
T56 2.97 2.07 1.43 1.00 .80 .62
Seems a lot on this site say that the 3.27 in the TKO is, if anything, too low and hardly useable....mind you, many are using 3.5 or 3.7 rear gears.
Now, I know you dont recognise the speed limit in Queensland of 100Klm/Hr (60mph)
but I'd like to cruise in an overdrive at that speed.
At say 100 Klm (60mph) the T56 should pull about 2000rpm in fifth...hopefully the cam wont cause snatching etc at those revs.
And..there is a spare .62 still to go for those odd occasions I get caught speeding.
First gear with the T56 would be
..............3.31 rear 3.55 rear
2000rpm 16mph 15mph
2500rpm 20mph 19mph
3000rpm 24mph 23mph
3500rpm 28mph 26mph
4000rpm 32mph 30mph
4500rpm 36mph 34mph
5000rpm 40mph 38mph
Given the light weight of the Cobra together with the excessive torque, do you not think the thing would pull that 2.97 first, or have I missed something??
After all, the WC T5 many are using have a 2.95 first.
Notice fellas...I debate with Queenslands but argue with those....well... you know who
