more than 20# , try 75+ little over 3/4 in across the whole block,
main area in the low dec much stronger.

Nope, you are WRONG; 20lbs is about right. it actually varies block to block and year to year. We had a thread on it with all the backup info a few weeks ago but I'm too lazy to do a search.

Going with a 383 because of weight is just dumb.

The weight differance is mabey 20# tops while the cube differance is 57 cubic inches, 20 LBS is not nearly as significant as 57 cubic inches

There is no replacement. For displacement. 440.

Not knocking displacement at all!! It's your choice. 440's do make great power, but they aren't the cure all for EVERY build or budget. If that was the case, 383's, 413's, 426W's
and 361's (yes, there are a gathering of them too!) would be sold for scrap at premium prices.
400's being the renowned platform for the "stroker
crowd", I give a warm reception for it. Great all-around motor, just needs a GOOD set of heads on it and then you can continue to build from there.
I'm not beating up on 440's at all, I just care for a challenge and the non-popular motors are MY challenges. A 500+ inch six
pack motor would make me , but a 390 inch
(383-based) dual quad, hi-rpm screamer stuffed in
a 3200 or lighter A body, "stripped" B-E body or
even in an AMC Hornet, Pacer or Gremlin, would be
just as exciting to hear as to see lay down a run!

so how exactly would you build a streetable 440 that runs on pump gas that would rip up the streets?

---

OK, only because I'm bored ;

- stock 440 bored however much it needs to be to clean it up
- decent lightweight rods and pistons; properly balance rotating assy.
- 10:1 compression
- hydraulic roller cam (perhaps a Crane 689531 - you can make good power with a number of flat tappet mech or hyd cams or a mech roller, but the hyd roller offers the low maintanence of a hyd without the wear concerns of a flat tappet cam)
- Edelbrock aluminum or equivalent heads
- Edelbrock Performer RPM intake
- Holley 850 carb
- TTI 1 7/8 headers, mandrel bent 2 1/2" exhaust and Dynomax Ultraflows

If you have more money; spring for a 440 source 500ci stroker kit.

Well,weather it B,RB,magnum or Hemi. Their all MOPAR BABY. I have ran them all but prefer the 440 less costly than the hemi and more cubes. An easy 500 hp and easier 500 lbs TQ keep it simple and dependible and enjoy lifes great pleasures.

---

K.I.S.S. principle IS MOPARS' longstanding rule of thumb, but they have also DARED to be DIFFERENT!! Reason: To keep the "competition" guessing!!

mmm intresting read ,go out take it out, put my 440 in it throw my 383 away,

---

How much for the 383?

really? four four tee. $ for $ in will stomp any BB mopar. (that includes Hemis)

Wasn't it a little too early for you to be

shoot cant be worth much now!! they just said a 440 can out run it!!
i dono , got about 750$ in the block 1100$ in heads, el-cheapo cam 300$
so throw it away ,hahah lol, i'am so scared to bring it out now ,with all them there 440 s going to beat me up

---

It's ok, you can calm down; nobody said that 383's can't run strong or make over 500hp. What I (and others) DID say is that if you built a 440 the EXACT same way, it WIll make more power.....it's not an opinion, it's simple physics.....not that hard to figure out really.
