Yeah i would go with that motor, it's already built with good parts and seems like a good deal...
When I rebuilt my tl1 i did it with a stock crank, rods, pistons, Fully ported heads & intake, stock size lighter valves, comp cams 305 cam (.510/.510 lift) crane roller rockers, comp cams rods, and some other goodies, Didn't spend a ton of money, but it made good power, the guy i sold the car to dynoed it at over 345 to the rear wheels. so you can make good power with out having to stroke it,....for the price i'd go with the motor that the guy who posted above me is selling.....
