455 out of car I am gonna replace crank and bearing i want to install new camshaft bearing and crank I should be ok to leave the pistons in???? some machine builder told me i have to take it to the bare block i think is is full o it whatzzzs up ?????
Well the camshaft bearings, you can replace with the block in the car. All except the back one, for that the block has to come out. As far as the crank goes, it will come out OK, but I would imagine it will be difficult to impossible to put a new one in, and avoid nicking the connecting rod journals, with the rods sticking out of the bores. If you are going through that much trouble, I'd do the entire shortblock.
GOOD POINT never thought of trying to align cranks soooo you are saying for me to replace the crank that the rods will be difficult to line up with journals and i should pull pistons too? thanks
When you're doing anything to a motor, may as well not cut corners or it will always come back to bite you in the :moonu: That is coming from experience.......I tried doing just a reman crank on a furd once and it wound up being a disaster. Once a motor has enough miles on it to need bottom end work, the top end isn't far behind and the effort and $$$ you spend trying to cut corners will all be wasted in the end. Do the whole thing right the first time and you'll be glad you did. :bglasses:
thanks thanks for the advice i was gonna do just that ..cut corners ..and for no reason just building a spare up ... thanks will do it right and once ...nothing worse then looking back saying ..i should of ... mike v summerville sc 71 riv 72 riv 74 riv
Well, Think about trying to lay the crank into the block, with the rods sticking out, and trying to align everything so that you can drop it right in. Pretty difficult. That crank is no light weight either. If you've ever watched anyone assemble an engine, they are very careful when installing the piston rod assembly into the block. The crank is already there, and bolted in. It's good practice to put some rubber tubing over the rod bolts, so that you don't nick those rod journals, and bearings. Like Joe said, do it right the first time, you'll never be sorry.
do it 1st time sounds exactly right afterward i thiught the same that is one heavy .... i drink to that heres one to the rite way..... thanks for bringing me around
