Looks like you have a steady hand too No runs or overspray anywhere, lol

I'm not using the intake valve covers or timing cover so I'm not worried

Finally got around to pulling the carb apart. Carbs going to get a complete overhaul. I think someone left it outside. It's got pitting and water damage the carb smells like a toilet too.
Air horn feels like it's welded together I hope the float bowl doesn't Have any water damage.

While that carb can surely work, it is not the style I like to use myself. I like the newer ones with added screws on the front of the airhorn. They resist warping as easily and have an APT lean stop that is externally adjustable.

Perhaps it's time for a moderator to move this thread into the LSx + Carb Swaps section.

I pulled the air horn apart and it's actually pretty clean. The carb was sitting outside though. Air horn gasket was swelled float looks new.

I think this carb has potential. I mean its an 800. They're cheap to rebuild and maintain and they can handle up to 650 hp.

So I finally got the motor up on the stand today. Pulled the intake off and it's pretty clean in there. I thought the motor was locked up at first but I think it's just got a light film of rust from moisture. But I got it freed up after work.

I think I got a leaky valve on number 6. oh well if it smokes a bit at start up so be it.

Hi y'all back again. Some of parts got here, including my oil pan seal. Pulled the pan on the vortec motor and BEHOLD. 4 bolt main. I'd say this motor was worth the 500 at 116181 miles. I didn't know that truck was a 3500 though.

The factory engine in my 1500 van was a 4-bolt. That is also a nodular crank. A bit stronger than the standard cast units. It likely has a single roller timing chain as well. The bad part is it probably has a single angle valve job on those heads.

From what I have seen, if it was a 1-ton engine it would have a longer windage tray and matching 5qt oil pan.
