Need input on combo in a very mild 383/496 stroker

I considering building a VERY mild source 496 based on my numbers matching 383.
I'm on a budget so I will keep the original 906's unported with stamped steel rockers and I need to use a low dual plane to make it fit under the hood. I want also to keep the original converter and 3.23's. The exhaust will either be HP manifolds or a pair of Hooker Comp 1 3/4" headers I have coupled to a full 2.5" h-pipe exhaust.
All this means low rpm's, but I want as much power as possible down low in the power band it will be used.
What cam/intake/CR would YOU use?
Always interesting to get input from an experienced audience!

Well, I have no big block stroker experience but if it is all the same to you, an engine is an engine.

Also forgive me when I say, I don't see a whole lot of sense of building a 486 with heavy limitations as described above.

But, these are the parameters and challenges given here today! I think I would....

Shoot for no more compression than 9.5-1.
IIRC, the Edelbrock Performer is no taller than a stock intake. Top it with a 750 cfm carb.
Cam size would be no larger than what the stock converter can take without compromise. The only example I can give is on a low compression '79, 318 where I used a mello Crane cam. The specs @.050 were;
216/228 -.454/.480-112
This used the stock converter and 3.21 gears on stock sized tires.

IMO, I don't think that 496 is going to act much larger than a 440.

You could try and be slick about the build and build it in a similar fashion as a F.A.S.T. engine. Obviously with the high stall, big cam and gear selections but the idea still holds in a much more mello fashion.

Good luck with the build!
I'm looking forward to it.

HP2,

I have been contemplated a stroker build for a 383 (Hence why I clicked on this thread), but for a street driven engine it just doesn't seem to make sense.

440source.com Stroker Kit ~ $2250
Gasket, Bearings, Cleaning Engine ~ $500

With the limitations listed above you seem like you would be better off to:

$1000 440Source.com heads or $1200 for Edelbrock E-Street (Get the 72CC Head and bump up the compression)
$300 Thumpr type cam, give your self low down power and sound!
* I Would lean towards a Comp 274 myself, but I know the Hughs Whiplash and Thumpr types are popular on stock bottom ends.
$500 Headers! Ditch those Manifolds
$500 Converter, ship it to a builder to have it made for your application

Note: Edelbrock RPM manifold, don't even look at another. This is been proven time and again in the forum.

I honestly believe the above go-fast parts would make a faster car than putting every dime in a stroker kit and keeping the 906/Manifolds/stock converter.

HP2, is there a reason for the limitations?

LMAO! My wallet limits me.... A LOT!
Or a the challenge of it all?

Just wondering

With all the respect, but I'm not looking for POWER or a FAST car. I already have a fast Charger, and it's loud, thirsty and mean too!
I want to build a low rev engine for a cruiser/driver. Since the block is matching but engine needs a rebuild I can get a 496 stroker kit for about the same money as refreshing the crank and rods, buy new pistons and have the rotating assembly balanced. It saves me time too.
Will keep the 906's stock other from basic cleaning up and match porting.

I want an engine that delivers from idle and up to, maybe 4,500 rpm. I will never go beyond that point. If it haven't been for space limitations it would have been tempting to go with a long ram intake, the model with the longer dividers
If I build it right I will get an snappy engine that lasts forever, is good on mileage AND it will feel like I have tons of torque on tap whenever I push the pedal.
OEM stamped steel rockers.
The Performer RPM intake will be too high, so probably a Performer.
Keep the original converter and the 3.23 gears.
MP ignition.
Still wanting input from that angle on CR and cam selection.
Thanks!

With the stock heads being the limiting factor, very limiting. IMO I would build a 3.75 stroke for 438 cubes. more reliable, same power.
I think the limited 496 would be great for a truck or heavy car.
seriously, simply not enough head for a decent build.

I'm not sure it will even go to 4500 given the heads. Honestly just the wrong idea IMO. If you want a stroker build a 426 out of it. That will work decently and give you a little more snap.

I don't see nothing wrong with your plan.
It will have the powerband like a truck engine, Cadillac had the same idea with there 500. Your 496 with 3.23 will pull like if a 383 had 4.30. I'd just build it to 440 magnum specs with no more than 9:1 cr.
If wanting more than stock 440 cam and
If using manifolds pick a cam designed with manifolds in mind. I wouldn't go more than around 268 degrees for what you want.
Any idle-5500 intake will do.
