Big block swap?

[dodgedarren]

Hello, I have a 1973 dodge Dart with a 440 and TorqueFlight transmission doner car.
Will the K-member bolt into a 1971 Dart?

Yes.

 

[dodgedarren]

Yes.

Are the upper and lower swing arms compatible as well???

So you have a 73 dart? WHAT is the donor car? no way to answer without knowing that.

The LCAs should be the same. The UCA has a large BJ compared to the earlier small BJs.

I do believe the steering linkage changed also. Might want to swap over everything to the 71.

I am still waiting for a answer to WHAT the donor car is.

 

[replicaracer43]

If he is sayin his donor is a 73 with a already transplanted 440, then yeah, it will all bolt in the 71, like has been mentioned.

Welcome aboard. As said the K will swap & the 71 uses biscuit mts as opposed to the spool type on the 73 K so each one would take a different aftermarket BB swap mtr mt setup. Center steering link (either 71 or 73 will work) tho they MAY each require a different idler/pitman arm(s)
