How much would it cost to build a 426 HEMI off a brand new block from Mopar?
Also how would you determine the red line?
About tree fiddy
I rather buy an gen III hemi block if I were to buy a crate engine from mopar
>>13932989
>gen III hemi
brb puking all over myself from fuel injection
>>13933060
Fuel injection is directly superior to carburetor in nearly every aspect.
>>13933060
>wanting carbs
enjoy your no power
>>13933085
So what? Sounds like shit.
>>13933090
that is a lie and you know it
carbs fault is lack of adaptation to the environment
altitude, hot, cold, etc mean fuel will be wrong.
at full throttle efi makes the same fucking power assuming equal intake manifold.
of course efi is better because of its ability to adapt. but not for power you dolt
>>13933096
you can have good sounding efi with ITB
there is nothing stopping people from doing that.
>>13933114
>you can have good sounding efi with ITB
I meant i want something that doesn't sound like a fart.
>>13933107
>efi doesnt make more power
kek
>>13933120
?
this is a normal ITB sound

boomer detected. get with the times, gramps
carbs are outdated, EFI is superior in every way

Yep, sounds like a fart.
Now hear this, a Hemi Cuda.

>>13933179
That's incredible. Modern tires and they are 12 second cars easily.
>>13933237
that feel when chevy was faster
hemi a shit
if it was so good why didnt they use it for racing?
the BBC was. and im not even a chevy guy.
>>13933172
then you should be smarter than to say carbs are better than efi
Anyway, Hemi heads are dated, there are better combustion chamber designs
>>13933245
Well because smallblocks don't weigh half of the total weight of the car.
>>13933257
>if it was so good why didnt they use it for racing?
Ask the NHRA, HEMI is only the most common engine used.
>>13933260
>then you should be smarter than to say carbs are better than efi
Never did i say they weren't better. I said EFI sounds like shit and it does sound like actual literal shit, like a man shitting.
>>13933257
The 426 was built specifically to race.
Hard to find a bare block right now last I head. You can probably find a few complete crate engines around for 15k ish though.
>>13933303
nhra is not real racing
nor is nascar
>>13933339
I see you've read wikipedia.
>>13933257
They did. It wasn't that common in circuit racing no, but it has been dominating drag racing since 1964.
>>13933339
Just wanna point out that this thing overheated like a motherfucker.
Still cool tho.
>>13933303
>Well because smallblocks don't weigh half of the total weight of the car.
it's not a small block
>>13933541
BBC>hemi
ITB's are amazing.

>>13933581
I'd say you like injection more than the engine it's on
>>13933703
you would think so, but remember these are bigger than 600ci, and aluminum block and head monsters making about 750hp at the wheels.
the hemis were still iron block. yep the bbc was better.
>>13933703
and im saying this as a ford guy, so i really feel no pride in saying this, but BBC>hemi
>>13932949
Best bet op. buy a 5.7 crate engine. It will cost about the same and will make about the same hp.
But you wont need to tune the carb everytime you want to drive it. Old hemi's are as finicky as 13b doritos
>>13933107
nigger carbs run rich ALL THE FUCKING TIME IN while in the power-band.
>>13933916
tune it then. smaller main jet
OP none of these niggers is going to know anything about how to build a hemi but I could help you out. First of all, don't buy shit from mopar, its alright but not the best, buy a block from indy cylinder. The block is good and its about 3000 for iron and 4000ish to 5500 for the aluminum depending on if you want a wet sleeve and I would recommend not going past 2000 with the iron (which would be the better choice). You can bore these safely to 4.6 and stroke them to high hell. I would recommend buying the crank and the connecting rods from them. Then head to stage V or arruzza and buy stage V hemi heads. If you feel like being a mad cunt, buy the dual spark plug heads but just to warn you finding the dual distributor for it is a pain to find. Get some ross custom hemi heads machined to perfectly fit in the stage v heads. Buy some rocker shafts and stands form arruzza. Are you writing this shit down? Do you want me to go on?
Also I'd like to add that carbs do make more power. Its just you guys don't know how plan and build shit correctly. But on any street vehicle I would recommend EFI. Better cold starts, superior idle, better BSFC at cruise throttle openings (which means better mpg) and it usually has superior throttle response (there are ways to make the carb better). Its just expensive, especially on a higher horsepower vehicle, and if any part of it goes wrong, its more expensive to fix. So I guys the money you save on mpg would take many years to actually even out with the initial investment
>>13933107
Oh by the way there are self adjusting carbs. They are called fish carbs. They're pretty rare but they're badass and have way better throttle response, mpg, and make more power than pretty much all carbs I know of.
>>13934044
>I'd like to add that carbs do make more power.
>>13934059
these days i really like the IDA style carbs. just simpler. a Dell'Orto is fine too.
sure they are pretty wasteful but hey do feel amazing when you get them right
>>13934070
Overall if you're building an engine, they do. Clearly you don't know all the shit you can do to the carb and manifold that makes it make more power than the EFI set up. It includes smoothing the entering airflow with a stub stack (pretty much what high quality pod filters do, they make more power than if you had no air filter) , adding a turtle to the intake, adding spacers, and smoothing the flow of air into the intake. You can even get a custom cam to counter act the short runners on the intake manifold for the center pistons to keep the intake opened for longer. There's so much shit you can do.
>>13934125
no they dont
efi has better fuel atomization
cars with direct injection can also retard the injection to run higher compression ratios
>>13934125
another reason i like IDA style. they tend to take to big cams better.
>>13934008
Just to add, never buy from Indy direct. They are cunts, use one of their dealers.
>>13934092
Oh yeah Weber carburetors are sweet. I like having style over function on a lot of applications. I haven't build an engine with them yet, but I do plan to soon.
>>13934092
individual runner carbs and 180* headers are great on those old vee aytes
>>13934136
Yes, yes I know, and direct injection also tends to cause a lot of carbon build up and causes the carbon to affect the compression and the hatching on the cylinder walls. I'm not saying all this technology is not awesome, because it is. EFI also allows for better scavenging, don't forget that. But I know from experience that if you're going all balls out for raw power, the carbs will provide you with more power, especially if you set everything up right.I'm currently going to school for auto and we have a few dyno's.
>>13934145
the thing about weber style is they are just so simple. they like big cams, they make a great sound, they just are not for beginners. you have to know what venturi size you need, and how to sync the idle.
but nobody will ever say they get the best economy.
>>13934140
Yeah, I've heard they're a bunch of dicks. Do you have personal experience?
>>13934196
>>13934138
Have you had any personal experience with these? It'd be nice to know someone who does.
>>13934197
>>13934213
Fuck I have to stop saying personal experience haha. And op where are you boy?
>>13934213
yes i actually have a few sitting around and have run them (both webers and del ortos) but not on a big block or hemi.
have a look
>>13934250
That's really sweet, do you always run a multi carb set up and do you have to do custom work with the throttle linkage?
Just throwing in that on a sbc or BBC quadrajet is the best carb ever made point blank period, as long as! You know someone to teach you to tune them. They are the worst carb in the world to tune.
>>13934799
Well just to say, a lot of the performance big blocks muscle cars of the day, came with hollies. Don't get me wrong though, Q-jets are amazing but once you get past 500 cu in, they're unusable, unless you run dual-quads.
>>13932949
>Also how would you determine the red line?
valve float
Gentlemen please, I think in this day and age on the internet, you should take the time to type out the whole thing when talking about Big Block Chevys.
>>13936760
What exactly do you mean?
