The "why not?" part would be easily answered for me by the $1329 price tag. I did a similar upgrade to my 292 but I used parts I picked up here and there for cheap. I probably have $200 in it. I don't have any idea about power/torque increase because I don't have a dyno and I don't drive it hard but I do get 18 mpg with an OD transmission. I have a small holly 4 bbl, offy intake, and split stock exhaust.
