I would go with a 283 or a 327 but I do not have one available. On the other hand this 454 that I picked up for 400.00 is nearly a complete long block and it is stock bore. The cylinders still have the cross hatches from the original hone job. It probably only has 30-40k miles on it. It is a CWB engine code which is either a 73 Chevelle SS or Monte Carlo SS. I know it's only a two bolt main but 400! I've seen the short blocks go for between 500-700.
