I have taken what many of the Original members have listed on the old site of what is needed and what is recommend to get for the TBI V8 swap so here it is if I missed anything let me know and I gladly add it to this list and hopefully it will get pinned.

1) The V8 (Preferably same year as your van but not necessary)
2) Motor Mounts (Available Two places Through Jakepatch or http://www.jagsthatrun.com)
3) TB bracket from V8 if not on motor
4) V8 fuel injectors (Need to put them on Astro TBI don't forget rebuild kit)
5) 7747 computer w/V8 chip Or new chip from http://www.tbichips.com
6) V8 exhaust manifolds or Headman headers (68600) (use copper gaskets)
7) V8 distributor
8) Wire and connectors to lengthen some wires
9) Nipple for the back of the manifold
10) V8 knock sensor if using TBI
11) Truck valve covers
12) Thermostat housing for V8 (Don't use V6 housing hole too small)
13) Front tranny seal (better do it now while its easy to get too)
14) Transgo shift kit

The following has been recommended by several members
(You don't need but are strongly recommended)

1) intake w/ all acc. connected from an 87-92 van or truck 305 or 350 will make connecting everything easy to connect rather than trying to make the V6 stuff fit.
2) Tranny cooler
3) Oil cooler
4) Flowkooler disc in waterpump vanes
5) 3 flu radiator out of an 89 Astro (heavy duty)
6) Taurus electric fan
7) vette servo

hope this helps you all!!! :banana: :layrubber:

I took the motor mounts from a V8 and two pieces of 1/8 inch steel plate and bolted the steel plates to the engine then bolted the motor mounts to the frame set the engine in then marked the bolt holes with a marker from under the van
took the engine back up unbolted everything then drilled holes and bolted it all up. It took a few times to get it right but when you have more time then money then you figure it out. If you want to try this I can (after the snow melts) take some pics and measurements of mine for you. Just remind me in a few weeks as I am forgetful. Mark
You forgot about the exhaust Y pipe from a V8 truck
