V6 3 speed manual

Like Aj said, the A230 is not enough and the 727 is overkill.
You typed A230.
Did you mean A903?
Cuz I think, according to the math, the A230 could be a reasonable and cheap compromise, with probably just a little tunnel cutting to fit a floorshifter.
Course if you think about it..... wherever an A230 fits....... so does an A833, and in this case I would recommend a Commando.
To the OP
With an A833,now; 3.09-1.92-1.40-1.00.. and 2.94s, you could be cruising 32= 2380 and down into first will get you 3840., and 65~2522 There is one for sale on FABO right now, put your money down.
