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 money!!!
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!
mimixownzall: I just put one in my '77 K5 Blazer. I love it.
Koskinator_S13: haha ig ot a 400 smallblock in my 79 scotsdale sound just like that haha
Jeremiah James: The big mouse is sick. take it to the doctor
Heath Sams: it it for sale
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!
Sal Alaimo: @tkhaze11 Doesn't sound good, bro! #8-\
burnnc10454: sounds poopy
dan thompson: @corey4406 open headers
corey4406: What mufflers do you have on this thing?
dan thompson: @Starkster50 yep it sure does. it had a bad plug. now she runs great
Jimmy: It will run like a champ when it runs on all eight.
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).
SuperJohncenarko: @gokuthaman777 i hear ya. loose some horses too.
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
toshamful: how much does a 400 coast
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.
dan thompson: @PT37 never calculated but i imagine pretty poor since i have 4:10 gears
