Depends on how much power/torque you are planning on putting through it.
THM400 will take more torque, but the THM350 is lighter and more
You may want to consider a 2004R or 700R4 if you plan on driving the
vehicle a lot. I know there are people who have strong opinions as to
which is better, but I have no experience with either so I will reserve
Planned specs on the motor, tires, rear gear (if known) and driving
plans for this vehicle may help us give you more specific advice.
replace "roosters" with "cox" to reply.
The 400 is less efficient, but not a big deal in a hot rod. It is the
absolute best transmission Chevy ever used that's not computer controlled.
If gas mileage is important to you, the suggestions from nate are right on.
You should have told us what engine and what you are planning to use the
For what it's worth, I have a 73 Nova with a mild 454 in it. Runs 12.0 @ 113
MPH. Many years are on its 350 with no problems except for a leaking dip
What is the intended use of the truck?
Want to get better mileage and still be able to drive it without
problems put a 700R4 in it. No computer controls and you get overdrive
and lower gear ratios to boot.

I knew they owned Around the House. Last I knew it was still open. I try
to stay out of that area, especially THIS weekend. I have been giving
directions so many times I'm thinking about just painting a map on the
side of the shop!
Between the Jordanville wind farm site, the Jordanville Monastery and
Cooperstown, I'll bet I can recite those in my sleep....
The truck will be for light hauling.
I want to put a Chevy 6cyl 292 in it with a automatic.
There is one problem I have to work out.
Where am I going to mount the starter?
I havent looked at this 292 in a while and dont remember seeing a
starter mounting pad under the engine.
It may be that I'll have to keep the original 4 speed floor shift truck
trans. I would prefer no to though :)
Look again. Not saying you are wrong. Maybe has 2 bolt-mountings--one
in b/h AND one into eng-bottom? What year is your 292? Seems as if I've
replaced starters in ~1966-1968 pkps that bolted to engine--plus, again it
*seems* they had 400 turbos-----been 30+ years, tho! Hope I'm right, as
it'd be easier on you! s
BTW: I'd go for the 400. It's inherently stronger, rebuild kits *used*
to be cheaper, and you can make it shift crisp w/out buying a shift
kit--Google & you'll probly find how; if not, email me & I'll try to
remember where to drill those 2 holes bigger in the v-body plate! And if
all you find is the really long tail-shaft one (375?), it's really a 400 w/a
long tail-shaft! s
never heerd of either of those.....
srry.....me be'n a tranny tech and all...i'd like to help,
but not being familiar with the options posted...
i must defer to brighter minds...
~takes a toke.......tightens up the last convertor bolt
on the thm400........mmmmm.....this ones gonna last
