I wouldn't myself unless money wasn't an issue. If your car has a 318, it's easy to build it or build another bigger cube small block to go in the hole. If you build a big block car, you have to change a lot to make it work. Purely economics for me. Like I mentioned in another thread, I can drive 4 hours north to a car show for less than $30. My friend with a 500 horse wedge costs him north of $75. Economics.
