Yeah I got a bit luckier than that and had one from a 70 monte carlo. Actually still have the motor on stand 16 years after selling truck. According to the net it looks like it should have been 330hp-410ft.lbs in stock form and mine just had aluminum intake and headers. Before swapping that in the truck had a stock 350 4brl in it so the 402 was a big improvement at time and actually picked up 1-2 mpg using same Q-jet, the 350 was pretty tired though.

For gearing if you want better highway rpm you might consider getting a m21y gearset and swapping it in. I thought about trying the M21Y in my Chevelle but ended up going to a T5 since I found one for decent price.
