One thing on any engine install that saves any grief later is to run the engine on a stand or dyno first. That lets you know there are no leaks, everything lines up and good to go.
How many of the million dollar shops do you see on TV they are in a crunch put the engine in and crap is running out everywhere and they can't get it started. I saw one of them go in I think three times before they got it right. Professionals, lol.
An engine run in stand is not expensive and sure saves a lot of headaches of putting engine and trans and everything in and then take it out again.
My friend that does restorations has one and always runs the engine before in the car. Timing set correct, cam and rings broke in nothing to do when in the car but go.
Check around someone might have one to rent or loan.
