The specs on ebay don't seem to match whats in the parts list that was provided.
ebay "390/428 rods"
list "390/427 rods" (could be a typo)
Then there's the mention of 428 service block, 406 was made for 1 race season 62/63 and based on the 390 block
The 406 is a solid lifter only block (not drilled for hyd.) the list says Hyd. lifters.
I agree something says "stay away from this one"
