It's a tight fit for a 1970 duster. I'm having clearance issues with the headers and the drivers side torsion bar. I can get more specific ones if you need...
Jason;
I have a 1970 Duster drag car that I am about to put a 5.7 in.
Were you able to able to put it in with trans and headers attached, or did they have to go in separately?
Also, power steering or manual?
Thanks
