No you couldn't-they'd have to be tuned length around 37" plus a proper length collector.
Honesty is the best politics as Stanley used to say. A 447 that makes 475 is a rebuild-period. That's been my beef all along and it's a shame (even) you got hurt for a performance build price.
At least you know Brent and the current crop of builders won't hurt you on price and it's cake for them to deliver a pump gas, mild 1.3 engine these days.
