'70 Dart 392 Project; what direction?

I had to go back and see what pan the OP is using. It appears the Holley pan utilizes those big bosses on the side of the block where the extra engine to trans bracket would locate. I'm guessing you'll find nothing that is a true bolt on because of that. I use the Milodon pans. You have to grind those big bosses down(as pictured in an earlier post) to get a mini style starter to fit.

It isn't the pan that is bolted to those 2 outer bolts. He must have the trans brace and it bolts around the pan to those 2 bolts (on both sides) and then to the bottom of the bellhousing.

I have the same pan and it doesn't use those bolts. Same as your Milodon pan, just in aluminum.

Guessing he will have to lose the brace, but time will tell.
