The Bluesmobile struggled at 8700' Crater Lake in this years Great Race. SO I have a nice 440 out of a 73 Imperial with the steel square bore intake. I want to build it to 69ish stock specs and run the new modern self learning EFI. I see some info on older threads but I would think these things get better every year. Not looking to scrimp $$$ so which is the best? We build engines and tune carbs so we should be able to handle install. As always, any advice appreciated. Stephen
