Factory cam regrind results/combos

curious of how many of you are using regrinds instead of buying after market and how well are you doing 1/4 mile wise?i was going to go big block but might stick around the magnum builds.la and big blocks are hard to find around here so I’m thinking about staying 5.9 they are everywhere and a reliable engine my 73 duster is s daily driver and like the idea off these mild 5.9 running so good
