Carb motor in a 99 silverado?

[Trevor]

yessir. And a 700r4 should be same size as 4l60e, you'll just have to run vac line to the module.

Turbo 350 isnt the same size? they seem to be easier to find but it really dont matter to me what tranny is in it. Also what do you mean vac line to module?

Also will whatever line connects to my transmisson to shift it from park work on the older style tranny?

What will swap off my motor accessories wise? Alt starter power steering a/c?
How will the alt wire back up with no engine harness?

And i know how the supply fuel line connects but what about the return line? and idk much about engine so the older engine has a egr valve what will that hook up to?

How bout this?!?!?!?

Get a LSX motor from a yard. Prob anywhere from 500-1K.

MSD sells a kit that gives you a MSD box and intake to run a carb on a LSX engine! Retains the crank sensor pulse so you can use all 8 coils. But you get to run a carb that sits on a edlebrock non-Fuel Injection Intake.

And you don't have to mess with motor mounts, headers, etc...

Then let the computer control the tranny. Or th350 or th400
