how to re-fresh 5.7 Hemi

i agree a complete donor vehicle is the best way to do it,,, piecing it together is to crazy and costly,,, if you go to street and performance web site,, there are some videos on there they converted a street rod over,, and they tell you a lot of info you wont find in the service manual,,such as the brake switch, that you CAN NOT re use,, its calibrated one time only,,and you will need one when useing all the stock stuff it controls the cruise control shut off, they show you how to calibrate it to your brake pedal movement,,take a lok you will see what im talking about,,, its on the 33 plymouth build videos,,,free on there site to watch,,
