Default 383-426?

what would it take to turn a 383 into a 426? could i just get some 440 rods and crank and have them prepped like a 451 stroker and add some custom pistons? or is it a lot harder? i was offered a 383 block for $100 and stell crank for $50 more. i think ill turn down the offer for the crank if i can make a 426 out of it. nothing scares people more than the #s: 4-2-6! bingo! i won the daily 3 with my "lotto" #s. im serious when i say there are a lot of non-mopar people that havent heard of anything other than the 426. not the 360 not 318 not even 440!

No, it doesn't take any extra. Muscle Motors has a kit and pistons for that combo, so you propably can get the pistons cheaper there than the custom ones.

so then i could use a 4.15" crank and really have torque? ill stick with the 3.75" standard issue mopar forged unit due to the fact it costs a lot less. it would be cool to have a 3.9" or 4.15" but the 3.75" is just fine. besides when i lift the hood of my dodge ram and they see a 426 air cleaner they will be in total awe as it is truly a 426. most of the people around here are mopar ignorant as i mentioned. if anyone from this board is from my area dont be offended as im positive i have met you. glad to hear it isnt a real hard job.

A 400 gives you a few more cubes than the 383. (Duh, really?) (as I state the obvious.) There's supposed to be a bunch of them littering the junk yards. I'd like to do that 451 motor someday. 100 lbs lighter than my 440. Project Super Stock 6-bbl's been running the build up of a motor like that.

This is just an idea here, do what you want with my total blessings, don't worry about being politically correct! The 426 that inspired the masses into awe was a raised block (RB). The 413-426-440 wedges shared this design. The Hemi block is an RB also. Most guys that want to emulate a 413 or 426 wedge just use a 440, paint it the competition hemi orange (yellower than street hemi orange that the magnums used) and put the early 60's "SuperStock" decals on the valve covers. The little old lady from Pasadena drove a "SuperStock Dodge". That phrase is what makes non-MoPar men into little boys real quick! Personally if I used a lowdeck 383 or 400 and stroked it I would not advertise it as such. I know I have raced "350" Chevys that really had 383 or 400 actual cubes. And I know EXACTLY what you mean about nobody outside the MoPar camps knowing what a 383 is. Most younger Chevy guys I talk to (after I wax them in my RR) thnk I have a stroked 350 Chevy in my "383" RoadRunner...!!!!! I guess they think only a Chevy can smoke them that bad. Again: It is YOUR car -- make it a good one!

I know what you mean about the chevy guys thinking a Mopar 383 is a 350 chev. My brother had the hood up on his car at a gas station and a chevy guy asked him if it was a 350 cause of the 383 on the air cleaner. I guess he moved the distributer to the front for the looks then.
As for the stroked 383, I would just start with a 400 and make a 451. It will make more power. I would tell people its a 400 or 383 cause thats what the intake says on it.

look dont get me wrong. im not building it just for awe factor. i planned on the 440 crank before i knew the actual cubes. its just that i then found that the so called "magical #" appeared. that means id have a short deck lighter version that has similar benfits as the 451/440. i was offered a 383 block for $100. a 400 block for $250. i just cant justify the price. around here just as there are no mopars on the road there are also no mopars in the junk yards. this is bs living in chevy land. even when i was in school only rwd was a few dodge p/u s. of course there was camaros firebirds mustangs ricers chevelles novas and stuff like that but not one hi-po dodge unless you consider any of the trucks hi-po.

thats the thing. i could just advertise it as a 383. ill put up with alota why'd you put a chevy motor in your p/u. "is chevy really that much better"? illl just have to say, "look @$$hole, look under the hood of your nova. is the distributor in the front? do i look smart enough to move it to the front?" the idea of advertising the 426 was just cuz im tired of all these dumb@$$es that havent heard of any mopar other than the 426.most of them dont know what a 318 is. thats pathetic.

i guess if any of you knew of a cheap 400 to build upon i could build a 451. i guess those plans will be put off for a while. im hoping to put a set of indy heads and some day way in the future put on one of those twin turbo setups. then if i find a 400 it will only be a matter of swaping all my stuff and getting some pistons.

Good luck! Regarding being in Chevyland, it is difficult to soar with the eagles when you are surrounded by a flock of turkeys. Hang in there!!!!

Hey curious,
Why don't you take advantage of the chevy guys ignorance of mopar iron. just because the chevy guys don't about a 318, 340 or 440 is no reason to limit yourselves to something they recognize. If I were in your shoes I would build the biggest engine that I could afford to and tell them it's a 318!!! Trust me
after you spank there backsides a couple of times they will all be clamoring to get a peak under your hood. happy building and mopower 2ya

Thanks

road runner69- yes it does. but if you bore a 426 over then you also have 431. 426ci is based on a stock bore.
valiant one- i checked ebay earlier on just the idea you suggested. found a few 273 decals and a few slant 6 decals. i couldnt pass it off as a slant six to most but there are a few idiots out there who'd still laugh at me until they get spanked.

you still didn't answer my question....If i have read this right you are using a 383 block not a 426 block right??? Nowhere do i see what bore your using? maybe i haven't read it right.


I was just wondering because im going to be building a 431 soon.

itll prolly be 431 in the end. im looking at resto 906 heads for $699(?) indy SRs at some point. cam will be very mild. very. prolly 750 carter or ebrock (later replaced by efi) on a torker 383 intake. alll of this is in prepareing for the possibilty of one of those twin turbos. at first that was just a exotic dream but know im seeing it can be in the future.

i may use a hogged out 1050 thermo quad for the time.(supposed to retain low end ) im using 440 rods becuase it gives a ideal balance as far as rod/stroke. 383 rods are good for more torque way down like in a towing application.

Curious, you say that the chevy guys will laugh at you ....Isn't that the way all chevy boys are and then they whine and cry and find an excuse when they get beat.


Rdrunner69,
I don't know how familiar you are with "b" engines so if I state the obvious to you please forgive me. a 426 an a 383
have the same bore at 4.25 . you are correct in your observation that a .030 383 block with a 3.75 stroke is a 431 hope I answered your question

your very right valiantone. in fact its kinda fun when they laugh becuase as you allready stated there smiles become tears. "thats not fair, you got more power"
Quote:
i like power regardless of the channels taken to obtain it. i just chose mopar 'cuz its the easiest. i can understand someone choosing chevy because of the price, but wtf would you choose ford? i wont laugh at your 460 powered pinto or your 350 chevette if you dont laugh at my 451 omni/colt. but i will try to beat you.
unfortunatly too many people will laugh at a brand they know nothing about. i grew up with 4 mopars in my yard. but unfortunatly i cant remember ever riding in any one of them or even hering them run. in fact they were all given away or sold cheaply. ( cordoba, plymouth wagon, 3/4 ton stake truck, and duster race car) so i never really gave a $#!+ about mopar. i was a chevy nut. but i never put them down. now im a mopar nut but i wont put down anothers ride. even if its a ford. some people have good luck with different brands. too many people hear that some brand is a POS and just harrass the driver. unfortunatly a lot of dodge owners experience that until they go and kick some @$$.

Before I put the indy heads on I had the same short block with a comp stick 248@.50 525 lift and about the same compression as you said. It worked awesome to with 915 heads it went 11.50. I would check with ultradyne about that cam with 10 to 1 comp. Dependes what you are doing with the car

the thing that will make mine stick out is that its going into a '87 d100 pick up. im sure itll scare the hell outta camaros. it ll be a kinda easy swap since lots of trucks came with big blocks and they have huge engine compartments. a dana 60 is a bolt in deal and most trucks w/danas allready came with 4.10s. i have a chance to buy a whole truck with dana 60 running (360?) and 727 for a $100. all i gotta do is get off my butt and bring a tow vehicle since it may not run too well. i have too many details to sort out for now.

i just hope i can hook up. trucks arent known for there "superb" traction

ill admit i expect a tad more outta my motor. i want low 11s to mid 10s or better. its asking a lot outta the drive train but i have a lot to work with using mopar parts. i was reading about a low 11s mild 440 in a dodge ram. i want more! my truck will be almost all race/street race. it was a limited edition of 1500 (1987 defender d100)but the slant 6/4 spd is gone. (no collector value ) it didnt have any options except towing mirrors and a cargo light. no a/c . im sure its lighter than most since there is no options and its getting a 'glass front end. if i cant trim off enough weight still, then ill start cutting in to the bed and replacing the metal with glass.
