In my book if your looking for cheap fun use what you got. Use the 8.25 and try to put a suregrip and some gears in it like 4.10s. Use the 727 with a b&m shift kit and factory hi stall TC. 340 cam with torker intake and 600 eddy, open headers and try to get it light. My guess would be 14.90s to 15.30s in the 1/4
