replacing a 305 TBI with a 96-2000 Vortec 350

[peglegs]

Ive searched a few 100 posts & dont have all the answers yet

I have a 1987 1/2 t, 4x4, 305/400 with TBI.

Im installing a 96-2000 Vortec 350 (create motor)

I will be installing the 305 TBI on the Vortec 350

Thus far i need to change the following from 1987 305 to 1987 350

* Injectors for a 350 TBI
* 350 specific knock sensor http://www.summitracing.com/parts/smp-ks7
* 350 ESC module (HEI module) http://www.summitracing.com/parts/acc
-35362/applications/make/chevrolet/year/1987/model/r10/engine-size/5-7l-
350
* 350 chip for my computer # 1227747

Ill also need to
* Change the 305 distributer gear to a melonized gear for the Vortec roller
cam
* I purchased the Power+Plus 4 bbl manifold

Questions
* changing to full length headers where is the most efficient location to weld
the sensor bung at
* instead of a chip if i aquire a computer that was installed in a 350 TBI
same service # as mine # 1227747 but had a 700r4 would the
fact that its programed for a 700r4 make it run bad ...w/o actually having
that trans? So far i cant locate my computer with a 350/400th. u have
one?
* Im a little unsure about the stock 305 distributor workn even with the new
melonized gear & the ESC module changed just feel like im missing
something here.
* the smog components will be deleted any ill effects ?does anyone have a pic of all the components that need to be eliminated?
