bbc tranny?
jdmhatchracer94:
ok 90 Silverado 1500 350/700r4 trans is dead and engine is on its way out. I have a 90 454 sitting here but what trans should I through behind it? I have read the 700r4 wont hold the tq of a bbc? A 4l80e is expensive and needs a controller. any have experience with a 700r behind a 454? dunno what to do with this thing.

Th400
snm95ls:
For what you would spend to make the 700 actually last behind the big block, assuming you plan to actually hook or tow, you could have gone the 4L80E route.
FWIW, there were 4L80E equipped truck in that era, so dig around and you might be able to find the proper PCM.
Otherwise TH400 is pretty bombproof unless you are getting absolutely silly.
Cadracer:
4l80e is the way to go and a stand alone controller is only 450.00
Can source that trans from alot of place easily and cheaply. 1400 dollars for a 700r4 to handle the stock torque of a 454.
i got a 4l80 setup with transfercase out of my 94 suburban with the stock 454 tbi engine. Still looking to do my cummings engine swap so looking for buy to purchase other parts.

When I was dinkin around online all I found was 4l80 or 80e assuming the none e numder is just like the standard tranny none electronic?
