GM used T400s behind big blocks, T350s behind small blocks & six cylinder engines. T400 strongest auto trans made. 36 ft 454 RV that weighed around 18,000lbs had a T400 in it. I wonder how long a T350 would last in that application.
Thanks for the vid brother, very insightful. Pro tip. Get a head mount go pro or a stand to free up your hands. You already have great quality looking and sounding videos. I think it would help us out🤙
Ive always used T400s in all my drag cars. Better to just start with a beefier unit designed for heavy duty use. Good, simple, strong transmission. Bolt right into a G-body with a 200R4 crossmember. Even stock shift linkage bolts right up. Easy swap.
I always here about hp...does vehicle's weight become a determining factor? honestly im looking to buy a transmission and im between a 350 and 400 so this video came in clutch...im a disabled vet so I only get to spend money once a year on a bigger purchase so if I make a bad choice its a long year paying for it... any info I'd greatly appreciate brother 💪🏽🇺🇲
Ill never be able to make the decision between 2-3-4spd on my car. Keep leaning toward an 80e other than parts are pretty steep. Just the normal 900ish hp tubro ls car around 3000#
@@jakeshoe in theory it is true because of the heavier parts of the 400, simple physics. The question is how noticable is it in the real world. A direct comparison would be nice. Running myself a TH400 and think about a swap to 350 but is it worth the effort and money?
I ran a turbo 350 with a Hughes kit trans break two extra reverse clutches a .060 thick also two two extra direct clutches the stock input drum and input shaft A HD spray in my methanol powered small block 427 NO power adder . The car with me weighed 2720 it made 660 hp it ran 1.25 to 1.30 short times 9.28 in the 1/4 mile for six years never a problem . Launched it at 3500 to 4000 off the trans break . I took it out to inspect it it was like I just put it together. It was tied in to a 8.5 GM diff with a 33 Moser spline spool and axels .
Excellent! Have never seen the comparisons between the 3 most common transmissions used by GM. Impressive how much power they can actually handle!
3 garbages but good videos

where is Jakes Performance?
Thanks for the video , so what would you recommend a 350 turbo or a 400 for a 383 full roller stroker motor ??
400
I love videos like this. Thank you!
There are cheap alternative hard parts from coan for the th350 handle lots of power.

I have a 84 caprice sedan just fyi so not a small car

Nice video, thanks for the information

The parasitic drag of the 400 is much greater than a 350.
That's the internet myth but doesn't prove true in the real world.

Not enough to matter.
I would think it would be ok behind a Ford
Yup, it's kinda like a fuse
lube curcuit is better on a 400 than 350 also

Which Hughes kit?
