WTF????need alot of opinions on this one!!!!!!!!!!!

ok. here is the deal. 1st car: i have a 70 340-4 speed duster, numbers matching engine,trans......... the front framerails are gone from accident years ago. needs quarters and all other normal rot fixed.

car 2: i am picking up on wensday a 72 340-4 speed car. the problem is, at some point, someone stole the vin tag off it at a body shop.so, the guy turned around and put a 73 duster tag on it and has had it tagged for 15+ years like that. i did get the origional fender tag that matches the rad support and trunk, showing it to be a real 340 and 4 speed.

bot cars need the same amount of work, and time put into them.

the 72 does not have the origional engine or trans. it has a ram built 360 that is putting out 465 h.p at the crank. it is an older setup, but has not been run much at all.

the numbers correct drivetrain i have prepped and was going to install it all in my 70 pink duster, but have been thinking.
1. should i instead, install the 360 and 4 speed into the pink car, and leave the numbers matching setup available, in case once i am done with pinky, i would have another project?
2. continue on as planned and put the 340 and 4 speed setup in pinky, and just pick up a solid roller to drop the ram engine into?
3. just part out the 72, as it has a like mint set of black buckets, either dougs or tti headers, all 4 speed stuff, i need the column for my pink car, 8.75,............................

give me some answers!
