Getting ready to swap a 5.7 into my 73 Dart Swinger

I actually have a second job now just so I can throw some money at it. I forgot to mention to the Builder that there's a dowel on the front of the cam that is broken not sure if I'm a need a cam as well kind of hoping he'll give me a good deal on getting a Comp Cam if so. My second job I build cages for side by sides going from that thick metal 2 thin gauge welding headers and y pipes really throws my groove off but after the build all I need is a wiring harness couple other things and I'll be wrapping up this chapter of having two jobs
