no..never even took covers off..it was a turn key engine he got and i just did the swap for him;;took the 312 out and built mounts and drop in the 429bbf..he was told it only had 400 miles on it and looks of outside engine it looked that way so had no reason to take apart..now it has me thinking is it a solid cam and some dumy put hyd lifters in?another concern i have is why didn't lifters pump up;;i can push 12 of them down with no effort at all..the other 4 not able to push in...
