Ax-15 to A833 swap

I just rev it to 7200=53mph, lol. Or
I flick the splitter-button, into First-over for 7200= 67mph. lol
But,
I'm kindof partial to shifting at 2800, cuz the engine is making this sweet song. Going from First (3.09) to Second (1.92) the Rs drop to 1740, and then my crusty old 367 has to wooook back up to 2800@ 33mph. She sounds so good singing under load!
Then into third (1.40) I get 45, then into GVod (1.09) I get 58, then, 65=2340 in 4-over, that's my DD mode.
Ok, I admit it, that's what I gotta do to get my wife to ride along, lol.
Hahaha gotta do what you gotta do to get the ol lady to ride along!!

I’ve looked into fixing the geometry for the clutch in my duster, called Malwood and asked about their kit , and it’s too much money and I’d have to pull the transmission anyways to do the conversion because I’d have to change the throw out bearing is what I was told. I also just kinda want the old school 4 speed for old schools sake.

If I throw the A833 in the car now and bolt it to the LA318 currently in the car, will I have any issues when I go to put a 340 in the car later? Is there a significant advantage to waiting and putting the 340 and the A833 in at the same time?
