Motor had stripped the plastic teeth of the cam gear and that had been replaced by the mechanic, motor was a little tappety, so some lifter lube was poured in.
He drove it about 200km and it was sounding really bad like a collapsed lifter and dropping a cylinder or two.
After pulling a few bits off came across spacers between the efi intake and the manifold and 2 sets of valley pans, and a number of other agricultural looking mods.
Also didn't have the same shaft mount rocker gear that was in all the images on the net. After a bit more research, it appears to be 4.4 P76 with a 3.5efi system sitting on top. He always said it had a lot more go than his old 3.5 and that he didn't think efi and extractors would make that much difference.
Will confirm tomorrow when I go look for the engine number.
After getting all the intake system and valley pans off, looked in the valley to see about a dozen banana shaped pushrods, don't know how this was even running.
Most of the lifters were also very concave on the base and the the cam was severely bruised and very worn.
Biggest thing now is do we just throw another cam, lifters and pushrods in, or pull of the heads and see what damage to the valves and pistons?
May pull out the plugs and use compressed air to see if the valves are still sealing and decide from there what to do next.
If I can get it running would love to delco it, as it currently only uses the computer for fuel using a MAF. It has a nice reluctor type distributor with weights and vacuum advance, at least easy to convert with a camira module.
Will try and get some pics to post up for a laugh.
