Suggestions/help for my 440 build/swap

Well

that would save me from having to scrape and grind all the old undercoating off the front fender wells!

Just remember to install a J bar of sorts from the firewall to the front frame near the radiator support so you can connect the shock tower to it. Once cut out, there is very little support. Not hard to do, just remember to do it. Then you can change your plugs through the wheel well while sitting on a roller chair using a ratchet and long extension if needed. I did this on most of them when I was hurt.
