Hi EFI-DIY,
I am also planning on building a 4200 for my '53 truck. I have a low mile 02 motor coming from a friend soon. At what stage are you on your ignition and injection. have you made your brackets/mounts for your EDIS system? I would interested in seeing your design and possably going in with you with your machine shop if its reasonable. I do most of my own machining but if you already have one made and they can just duplicate, no sense in re-inventing the wheel right? I plan on turbocharging as well, but not at this stage. I think I will pull the head to do a little porting and cleanup, maybe open the chambers up a bit to lower the CR. Feel free to email me.
Hans
