alright, get some pictures of the underneath, what bellhousing is it? take some pictures of the transmission and transfer case.
Check the angles of the driveshfaft.
What is left on the motor? What type of motor mounts and adapter did he use? check the rear sill and the door sills underneath.
The tierod isn't hooked up to the power steering. It looks to be a Saginaw power steering pump. The radiator isn't in, the pulleys aren't hooked up, he did a shackle reverse on it, the heater core is missing, honestly man I wouldn't pay more than 4.5k-5k for that without the motor being ran. It has a new water pump but he has the front bib on without the entire motor being put together meaning he gave up. We put our motor in and everything hooked up and ran it really quick so if you are handy and got pockets go for it. It looks like it was a wheeling rig, fenders are cut and a really ****ty shackle reverse. so depending on what you want to do with it you may have a deal.
With a 350, plan on a new radiator and a shroud. You will run hot temps and make sure there is room for about a 18" fan. Check the power steering pump as well. Have to have a good amount of clearance. See if it is advance adapters conversion, Its a 4 speed so that is good but I would make sure the conversion is done right.
How old is the engine?
Background- I have a 74 that I just put a new 350 in and have been all the way through what your doing. Depending where you are, I assume he is asking about 8500? If you are in Austin or Dallas that's what I would assume. I paid 7k for a 350 conversion with a blown motor. I am in it for about 10k, new transmission, TC, Motor. gas tank etc.
Id be happy to help but get some more pictures of the entire drivetrain. Hows the fuel tank? that's 500 from a Toyota dealer. How are the seats? Hows the radiatior? has he had cooling issues?
Mine is just a ranch vehicle, but everything is expensive as hell on these. If you are handy, they are a blast.
I drove mine before he blew the motor so I knew the rest was good to go. Check his power steering clearance if he is selling half way through a project and the motor is in, id be curious why its not much more to get going from there.
