Have you looked on here or around for something already together? I only ask because you can save a bunch of money that way. You can find good deals on heads, intakes, carbs, short blocks and even stroker kits.
I am just getting started and trying to figure out what I want to do with this engine. Have had a few contacts that have stuff they want to get rid of but I don't want to buy till I'm sure of what I want to do. Really appreciate all the information for sure!

On the top of page 4 in the "Engines For Sale - Big Block" there's a 451 shortblock, fresh, $1800.00 in TN. Road trip??

It's an RB , so it's a 440 block bored .055 , I'd want to see a sonic check on it .

I am seeing that. It's nearly a couple hundred bucks to clean up a block and tell you if it's OK to even use it!
What is to be included in your 3k budget? Is this a short block?, long block, or complete sitting between the fender wells ready to run?
I'd been asked more than once to see what can be done on a $2500 budget. This was a few years ago. The guys that were asking were starting with running low compression 440 engines. After looking in detail at ALL of the costs and being true to the budget, there was only one conclusion: Prepare a good set of 915 heads, mill the heads to the CR you can get away with, and add a good cam and timing chain. Nothing to the block. That's it. You'll maybe have a couple hundred dollars left over, at best. That would be the best performance gain given the budget. Today, maybe substitute the Stealth or Edelbrock heads for the 915s.
JohnRR - If you went 98 mph with a stockish 383, that is as good as I've ever witnessed. I cannot ever remember seeing a stockish 383 (even some with headers and aftermarket carb) break 100 mph in a B body. Enough gear and tire and they might go high 13s.

I was hoping for short block at 3k or less.
Oh - no heads or valve gear?

Lots of choices... If you want or need to stay in budget, you can get a nice running stock looking 383. Compression around 9:1, no quench, iron heads, decent cam. Lots of fun to drive. Don't let me or others talk you out of it if that's right for your app. Care in piston choice and machine work will make it noticably stronger than original.
The next step up would be 440 source or Edelbrock heads. Next after that is a stroker.
Fully rebuilt 383 with new parts for 3K. Really?

The car is a 69 383 Dart and it was as stock as the day it rolled off the assembly line except the exhaust , it went 99.7 with the same tune I had at the pure stock drags at my home track which is closer to sea level , I think it's 90 ft , and it was a nice clear day , no idea what the DA was. The car has 3.91's on an F70-14 tire, I am not sure what affect the timing chain had on it and I never ran it with a fresh chain. The car will go back together with a fresh engine and 4.30 gears, the only real deviation from stock will be the compression bumped to factory advertised 10.0 and a cam that is very close to the 70 spec cam, I'm hoping the car will run low 13's, one person I talked with at the PS drags thought I could get it into the 12's, I don't see that with the 4 speed and me driving it.
Beefreak , you should be able to do the shortblock for 3k I would think. If you decide to go the stroker route I've got a set of Flat top Diamond pistons I'm looking to sell.

Thanks John. What exactly are they (part #) so I would know once I figure out the combo? New/used?

I have not looked into doing a low buck 383 in a long time. I rebuilt the original 383 that came in my '71 Charger with one of the inexpensive Summit "kits" that was about 20-years ago, but the kit had forged flat top pistons and all the bearings, rings, and gaskets. I don't recall the brand or part number, but the pistons sat below the deck. I used some 906 heads from a '68 383, and ported them using the Mopar templete kit, then had them rebuilt with new valves, guides, and hardened exhaust seats, and milled 0.040" to get back a bit of compression using the 0.040" thick Fel=Pro head gaskets. The cam I used was the Crower Compu-pro 271HDP (271/284 adv duration, 222/234 @ 0.050" duration, 0.486"/0.496" lift, 112 LSA) It made good mid-upper power and I would shift at 6,000 RPM, but not much low end torque with the (maybe 9.0:1 compression or lower). I was using a stock 1800? stall converter and it just did not work well. I really needed a higher stall converter. The valve train was stock rocker gear with slightly shorter Ford FE pushrods (same ball-ball ends, but oil through design and about 0.030" shorter than a stock 383 pushrod.) I tried two different intakes, A Weiand Action Plus dual plane, which seemed to perform about like the stock 4-bbl, and a Weiand X-Cellerator single plane. The engine seemed to make more power with the X-Cellerator, but it also made the low end even worse. The performer rpm would have worked good on this engine, but it would be about 10 years before that intake was avaliable. The carb was a Carter 750, and it had Hooker headers, and dual 2.5" exhausts with superturbo mufflers. I had accidently over-reved the engine because of the stupid shift kit that lets you select first gear at any speed modification and worn out shifter bushings. Anyhow, I had a few intake valve hit the flat top pistons (the pistons had no valve reliefs), so I ended up with bent valves. Anyhow, That 383 setup was the most dissapointing engine I have ever built. At the time (early to mid 1990s) piston selection was really limited (if the affordable range anyhow), and aftermarket cylinder heads were pretty limited. This is when I bought my B-1 B/S heads. I was thinking of using them on the 383 short block because the heads have small 65cc chanbers which would bring up the compression ratio. After getting the heads with 1.6:1 rockers it was obvious the pistons would need valve reliefs, and I really did not want to tear a fairly fresh short block apart. Anyhow, the 451 strokers were getting some attention at the time, and it just made more sense to use the heads on the 451 stroker 400 block with Ross pistons that had plenty of reliefs so I could run a bigger cam. Anyhow after going to the stroker, I totally lost interest in the old 383. The stroker was making almost twice the power as the old 383, and the rest is history....

john, on your 383 in your dart,where your pistons down in the hole? i hear alot of folks talking about poor compression ratio on these motors in factory form. i have 3 complete 383 magnums here(2 are from 2 different 69 roadrunners/ 1 from a 70 super bee) all were very low mile cars,untouched,all stock,and all 3 of them have the stock flat pistons in them and are zero deck. just curious how much variation there could be.
Technically yes they are in the hole, the CH on the stock 68-69 383 4bbl piston is 1.932, on a blueprint block they are .003 in the hole, the pistons in my Dart's 383 and another 69 383 HP I have are .003 in the hole. With stock heads from the factory which are in the 90cc range, the sets I have had cc'd were 90 - 92 cc, the compression comes in at 9.2 on an actual factory rating of 10.0.
I'm not sure about your 70 383, what's the assembly date, because the 70 383 has different specs per NHRA than the 68-69. Many claim that factory blocks can be as much as .020 TALLER than blueprint , the small amount of engines I have done have not been that high , all have been very close to the blueprint spec so who knows ?
the engine rules for the PS drags are changing for next year , the yare going away from the NHRA specs for a number of reasons and are now allowing as much as 1.5 over stock, but from the conversation I had it sounded to me they would like to see people build and certify to factory advertised which is what I am now doing . If you take a 69-69 383 , putthe piston at .003 to zero , steel shim head gasket and 80 cc heads , depending on the overbore , you can come in at 10.0 - 10.14 , My pistons will have very small valve reliefs and be .002 in the hole , with my heads I should be right at the 10.0.

Ok, I started looking to see what is avaliable and affordable. Here is what I came up with to build a decent street performance 383, that should make around 450 HP, and cost around $3,500. The $3,500 does not include oil pan and pickup, Carb, ignition system, exhaust system, or cooling system.
So here is what I came up with (copyed and pasted from my spread sheet):
383 PARTS LIST PART DESCRIPTION COST Notes: Pistons KB-400-030 $345.99 9.5:1 to 9.8:1 Domed piston using 80-84cc head, 0.040” Gasket, 0.024” below deck. Cam Kit Lunati 60303LK $209.95 Cam and Lifters, 3-bolt cam Gasket Kit Fel-Pro QKS2110 $55.95 Rod Bolts ARP 145-6002 $61.31 Piston Rings Sealed Power ZE233K30 $48.95 Moly top ring, not file fit, mild performance app? Main Bearings Clevite MS876P $62.95 Performance Set – standard size Rod Bearings Sealed Power Z82320CP $64.95 Performance T-77 Set of 8 – standard size Cam Bearings Dura-Bond PDP-17 $24.88 Prefered performance cam bearing for best fit Freeze Plugs Sealed Power Z3818011 $12.99 Brass freeze Plug Kit Valley Tray gasket Fel-Pro (112-1002) $19.95 440-source price Oil Pump Melling M-63HV (440 S Price) $65.95 High Volume Standard Pressure Oil Pump Oil Pump Bolt Kit 440 Source 109-1502 $9.95 Longer bolts for HV pump Oil Filter Fram HP-1 $9.95 Oil Filter Timing Chain Set 440 Source 102-1004 $74.95 3-bolt timing set, double roller Timing Chain bolt kit ARP (440 source 129-1007) $8.95 Harmonic balancer 440 Source 200-1083 $89.95 High Strength Steel, non-sfi Cylinder Heads 440 Source 200-1055 $995.00 Cylinder Head Bolt Kit ARP (440 source 129-1005) $79.95 440 source brand 109-1514 = 44.95 Spark plugs NGK $24.95 440 source – Champion 3/4” reach 138-1000 = 24.95 Intermediate Shaft Bushing 440 source 101-1001 $7.95 ARP Main Stud Kit 440 Source 129-1008 $59.95 Intake Manifold Edelbrock Performer RPM $239.95 440 source price Sub-Total $2,575.32
Machine Work Clean / Hot Tank Block $50.00 R&R & Fit cam bearings $30.00 R&R Rod Bolts and recondition rods $100.00 Align Hone Mains with ARP studs (if needed) $100.00 Mill / square Deck $100.00 Bore & Hone cylinders /w Torque plates $160.00 R&R pistons (press fit pins) $24.00 Turn / Polish crank ( if needed) $100.00 balance engine $200.00 Sun-Total $864.00
Total = $3,439.32
Power estimate using headers, and 750 cfm carb: RPM HP TQ 1000 59 308 1500 95 332 2000 130 341 2500 180 377 3000 234 410 3500 278 417 4000 327 429 4500 388 453 5000 433 454 5500 452 431 6000 454 397 6500 445 360 7000 420 315
As you can see, not much torque in the low end. If the deck is milled about 0.020" the pistons should be at 0.004 below deck (not the dome part) and that would boost compression to 10.27:1 and add about 10 ft/lbs of torque to the power band (and also tighten up the quench, but the dome would have to be checked for clearance.) These power numbers were estimated using low port flow numbers that someone reported as out of the box numbers. with some port cleanup and the milled block peak power could be around 475 HP. Numbers were generated with the Dynomation 5 sim, wave-action model, and when I tested larger cams, they seemed to really hurt low end torque even more.

I looked at my spread sheet briefly the other day but was to lazy to really go through it. Thanks for going through it and posting. I would probably remove the APR studs, oil pump and RPM manifold and use the existing main bolts, add a high pressure spring to his existing pump, and buy a used DP4B. On the flip side, I don't see the intermediate shaft, and I'd add a windage tray, new stamped rockers, shafts and maybe pushrods. Are there valve springs in that kit? Shipping will be a little coin, and my machine work here is a little higher.
