Looking for a shop to do some engine work on my GTO.
Over the weekend I had a valve spring decide it no longer wanted to be a valve spring anymore. It snapped and dropped the valve and now I have valve in the shape of a pretzel. One piston is trashed, cylinder liner and one head is toast too. I haven't pulled the other head but found all the pieces so I think the other side is probably good. I also haven't pulled the bottom end but I think (hope) the crank and rods are still good.
Block is an LS7 block so I think it makes sense to resleeve it, rods are compstar 6.125 rods (I think they are the H beam) and Cola 4.000 stroke crank. I dont recall the specs on the cam so I think I will actually replace that during the process.
I dont feel like messing with it at all so I just want to drop it off and pay once its done (I dont really want to pay but I will
)
So I am looking for a shop to
Pull the block, disassemble it and have it resleeved
Help me pick out camshaft and possibly heads
assemble block with new pistons etc
re-install engine in GTO
retune as needed
Think that is it.
I know Livernois is a sponsor here so I will probably have them quote it tomorrow but it's always good to have a couple of shops quote the work So I am basically looking for some recommendations.
Thanks!!
Pics of carnage, engine had some major carbon build up for some reason. You cant see it in the pictures but the cylinder has 2 small cracks (or thats what it looks like to me).
