331sbf: the bad thing about the 400 is the horrible rod ratio.they wear out too
soon because of that(more wear on the thrust side of the pistons).the 327
was the best gen 1 sbc I think.they lasted longer and made good power.build
a 400 with a 327 crank and have fun :) big bore short stroke just like the
big boys(nascar engines).
burnnc10454: sounds poopy
toshamful: how much does a 400 coast
MrAbrink: now thats what Iam talking about!!! I want to build a torque monster out of
a dart block 400, its going into a 77 3/4 4x4 . just takes money money
JackBuck44: Anybody know how one of these would work in a 1957 chevy belair?
xorog: If your motor was cold and you rode it to 3100 RPM you're an idiot. Nice
motor but NEVER rev up a motor before its warmed up unless you feel like
replacing rods every couple days
CliffordTransAm: Sounds EXACTLY like the 400 in my 85 Chevy.
dan thompson: @xorog Don't worry i warmed it up before i made the video. might be cutting
out cause of the old gas.
i80steelers: junk that fuker
kendellewis95: How much you asking for it...
kain hall: OMG, i jsut found out my 1977 K10 has a 400SBC in it and not a 305 liek i
was told...... cant wait to get her timmed right!!
PT37: what mileage you getiin
Sal Alaimo: @tkhaze11 Doesn't sound good, bro! #8-\
dan thompson: @MrVicarious666 that actually sounds like a great set up for a 400. we have
another 400 we are building and planning on doing the exact same thing.
just make sure you have the steam holes drilled in the heads before you
have them put on your 400. the reason you need to have to drill steam holes
is because the 400 has siamesed cylinders.
devenson1: i think the super cavi could take it!! lol
dan thompson: @PT37 never calculated but i imagine pretty poor since i have 4:10 gears
jamespbrownjr1: i have a 85 chevy truck whit 408 it run in the 10s
corey4406: What mufflers do you have on this thing?
SuperJohncenarko: @gokuthaman777 i hear ya. loose some horses too.
dan thompson: @corey4406 open headers
Jeremiah James: The big mouse is sick. take it to the doctor
Heath Sams: it it for sale
kain hall: @toshamful it depends...you cnat buy a 400 new as chevy only made them from
1970-80. best bet would to look at old trucks made before 1980...like K20's
and heavy halfs. i will sell you my 400 for 2 grand! (evne if you offer me
that i would not take it...love my 400) but, it really depends. if its all
tricked out..a lot, if its a rust bucket...they might jsut give it to you!
HARO934: haha ig ot a 400 smallblock in my 79 scotsdale sound just like that haha
shaikhdishgan1: love 400 sb ,with allthe good and bad ,i love it it have the right size and
can give big power torqe is it`s game i put one in buick skylark with mild
cam head cleaning port matching modefied rochester it was so torqe that i
nerly lost my old trans first testing
Sal Alaimo: You need to sleeve that motor and, like 331sbf says, throw a 327 or another
smaller-cube crank in there. The motor sounds like it has a nice cam, but
you can tell that the miss is there. You need fresh plugs, perhaps. You'll
be fine with a little overhaul!
dan thompson: @Starkster50 yep it sure does. it had a bad plug. now she runs great
DORKYBA55ATTACK: I love the 400 small block, more than I love the 350. I don't understand
why people buy a 400 small block, ditch the block and just keep the crank
for a 383. No replacement for displacement!
tkhaze11: I have 1 of these bad boys in my 91cheyenne 5spd I love it I havnet learned
not to clutch dump so I've got thru a driveshaft a rear dif and like 6u
joints..desided to buy cheap autozone ujoints that's y I go thru them quick
tried the tuff1s and that's how I bent the driveshaft in half and flipped
the diferntial...lol to bad right now its only on 7pistons still has alota
power tho :)
rjc862003: sounds like the timing might be off a touch
dan thompson: @shaikhdishgan1 yeah, after i put it in this truck i busted a u joint and
then shortly after that the rear end went out of it.
zachmajic89: I like where you put your tach
Yoshumari: what a messy engine bay
dan thompson: @tkhaze11 yea i managed to take the rear end out only running on seven
cylinders. turned out it was just bad plug. very good torque motor.
trunk516: i keep a roll of duct tape on my shifter too...LOLLL
Starkster50: It will run like a champ when it runs on all eight.
88TransAmGTA: how much HP you think it have P.S. what is the averge 400 smallblock HP
fox924: nice truck
mimixownzall: I just put one in my '77 K5 Blazer. I love it.
SuperJohncenarko: @i80steelers it has a carburetor genius, they are naturally aspirated, so
the motor will quit once mabe, and it will lope then start to drown out.
hes got nothing wrong with the motor we have one, it is perfectly fine. it
usualy does that when it hasnt been started in a while
