that would be a good start, but if you can afford it buy a rebuilt long block from GM and save yourself alot of headachs.

400 is good since you own it but I have always been a fan of the small block chevy 350 with HEI ignition. Again a lot less headaches especially if you can find a 4 bolt main.

a good 383 stroker would pick the front tires up nicely
