I am still trying to determine what to put in my 71 challenger convertible. I bought it with a 1972 400 that needs a rebuild. Its going to have a 5 or 6 speed tranny but I don't know if I should build the 400 into a stroker motor or put in a 5.7 or 6.1 hemi from the bone yard. I know the conversion kits for the hemis have got much better/easier.

What would you do if you had the choice? I'm also assuming the prices will be somewhat similar after all is said and done, would you agree?
