What will it take

[8door]

As soon as my 68 is done, shooting for Jan Feb 08,I want to try a little something different for me any way.
I have 1990 Chevy Astro van with a 4.3 and and a 700r that I have owned since new. Was going to sell it but found the resale on these things are extremely low.
So here is my thought. I could pull the engine and seats and steering A/C lots of parts and put into a truck. Maybe a 47-54 I know there is another board for these years, but there are more guys here and I do have a 68
Anyway what will it take to transplant the engine? Drive shaft is open older trucks are closed right?
What about the TBI injection
Is there a different type of fuel delivery as in pressure?
Any ideas?

All it would take is money and a lot of time fabing. I put TPI in my 71 and I did it all myself. No kit's back when I done it in 89. Anything can be done it's how much are you willing to put into it that matter's.

for one you will need an electric fuel pump, 9 to 13 PSI. this woule be best done with a rear tank swap from someone like Fuelcellguy.
I would rob all the engine wiring from the van along with the ECM.

the engine is a bolt in. that's the only easy part.

As it is a TBI, what would be the possibility of using a regular aspirated carb? Then I would not mess with ECM and other electronic controls.
Is the transmission sift controlled by the ECM?

There should be someone out with a carbed manifold for the 4.3.That would save some work as long as the engine has the old style distributor and not a reluctor wheel and coil pack set-up.You can use a toggle switch for the lock up function on the 700R4.You may want to look at the weight of the truck you want to put it into.A 49-55 first series may be a good choice.Check the frame(if it's not a unibody).There are a lot of 49-55 conversions using the S-10 frame.That may be a workable solution.

It has the old style distributor so that will work OK. I'm not sure I understand your reference to the weight? and frame?
The Astro has a unibody, that's the only way they were made.
I can get confused : I looked at your Join the Chevy GMC Truck International and thought what is the connection with International trucks

If the weight is close the performance and handling should be the same.If it were a vehicle with a frame it might be possible to swap a body on easier than swapping everything over to whatever you were building.If you use the 4.3 in a 1 ton dump you would probably hate the way it performed.If you used it in a Opel GT it would probably run like a scalded dog.

Since you have a donor car, the only wires on the TBI you need to change are:
constant power
switched power
ground(maybe)
and start signal.
You may cut some out that go to the instrument cluster.

It took me longer, but I have seen people do it(TBI engine swap) in one day.
I would keep it for mileage and driveability.

Sounds like I can keep the TBI and locate the electric fuel pump that it now has, maybe inside the fuel tank?
Or install an external one.

Hummm ..........wonder if I can use the rear axle.
