Way back in'08 efi diy and I did a demo at the Inliner Picnic at Bonneville. We put a temporary GM TBI with a Megasquirt on the 270 GMC in my '53 Chevy pickup. I never made the permanent switch because it was intended for another truck. The '53 is just a couple of hours away now. I guess I should just do it. There are some posts here about it and about the help that Marc gave me on putting my Megasquirt together. Here are some pictures that may help. I could try to dig out some of the old posts if you want.
