Good answer, Brent. And Gord's reply is right too. Getting it out is the easier part; getting it back in is what gives me fits!
I like this type of question because everyone has his own personal answer.
Only if the car is set up for fast engine changes can there be any fast times.
In 2002 when I ran my last model A hill climb at Riverside, I had the car set up so 4 of us with air wrenches could have the engine on the floor in 12 minutes. 18 minutes to reinstall, minus oil. If you build a car from the frame up, it is not hard to set it up for this. Expensive but not hard.
There was no reason to do all this except it was big fun and I had way too much time on my hands at the time.
Pete,
Talk of fun, I'll bet it would be fun/interesting to see a video of you guys doing that remove/install! Probably learn some of your secrets for such also.
I suppose this same scenario would work when installing a transmission to an already installed engine???... use two 3/8 bolts (-one about 2" & one about 3" long) and remove the heads with a hacksaw and sharpen the area where those heads were removed to a dull point. These new alignment pins can be screwed into the flywheel housing on opposite sides and used as aligning pins. Since one is a tad longer, as you are pushing the engine into the chassis you will align it first and then rock the engine so the pin on the opposite side enters into the respective hole on the clutch housing. This will get you very close on alignment for the input shaft to engage. Once the engine has married with the transmission, just back those studs out with your fingers and install regular fasteners...
Ok now, who did I lend that chainfall to? I went to install new leaf springs in the 49 and realized the spring bushings were bad. spent 4 hours looking for new ones now I need to order them. Nothing for me is as quick as it should be.
Never pulled an engine from an A before, didn't look at the clock, but I got half way thru my 6 pack.
