Fuel pump arm swap SBM-SBC?

So geometry wise...how confident are you that the pivot points, arm length, and plunger throw is going to render this functional? I admire the creativity, I made my own fiberglass bumper in the same spirit. And only 150 man hours later, I had a decent bumper at least 82 percent as nice as an AAR, and I saved at least $8. Lol
