hi,my first time here.i've got a v12 engine to rebuild eng# H115449 as far as i can tell that should be a 1941. now,it has solid lifters,i can see wher they tappad the oil feed to the lifters and plugged it. i will put it back to hyds. the rod thejournals are hollow , you can look right threw them.i'm ok with that. the engine i pulled out of the car a ,48 the crank is solid. but that engine was not the original one for the car the block is cracked. i could not find the engine # one that one ,it had a hyd. cam. i just want to make sure i can use the componants together with this eng. and am wondering what year the crank is etc. thanks.
