Does it have to be 383? A 440 would get you there so much easier.

---

I am currently out of 440s, except the finished solid lifter done 500 stroker I have sitting in the shop, that was originally for a drag car that I wont be using now. My engine builder believes that its best to use that motor for what it was intended to be for or sell it or trade it for a done motor for this car. So I was hoping to build the 383 that I have.  But This is why I am posting the thread. To weigh out my options.RUMBLON

Can you get a stock stroke forged steel BB crankshaft that is not turned on the rods? If so you can build a really nice street stroker using a BB crank(fairly inexpensive with a good shop, you will need to turn the mainss down also to stock 383 sizes ) and have it offset ground to BB Chevy rod sizes with a 3.91 or 3.90 stroke, 6.8 or 6.7 long BB chevy H beam rod and a custom piston with a dish or reverse dome fo compression under 10.0 to 1 , not above with stock close chamber iron heads If you decide to go with a set of new aluminum heads then shoot for 10.0 to 10.7 to 1 compression for premium pump gas I don't have the exact C.I. for a 4.280 to a 4.310 bore with a 3.91 stroke but I'm sure it is near 450 C.I., lots of torque and good HP And it lloks stock

Why not just change the cam and the intake on that motor and use it if you have no intention of doing a drag car now ? It would be alot cheaper than building a new engine and you are going to end up selling that 500" engine for pennies on the dollars you spent building it. Of course this is ASSuMEing it's not a 13.0 compression engine.

And so what if it is 13-1? It would still be much cheaper to change pistons in this one than to build a whole new engine that would have a lot less potential.

You forget, more than likely, having to rebalance for the heavier piston.

How about just use the 383 with a good balance job

Put these pistons in it:

http://www.summitracing.com/parts/SLP-WL2315F30/

Fresh 906s with good valves and springs (little extra coin from them):

http://www.aeroheadracing.com/id6.html

Hughes whiplash cam:

http://www.hughesengines.com/Index/produ...mp;partid=25115

And this with just 100HP jets:

http://www.dynotunenitrous.com/store/scripts/prodView.asp?idproduct=192

Should make 450hp

I know I love the sound of this cam at idle and it is supposed to be ground to cater to low compression.

Ill let you know how this works because it is the EXACT combo that I am going to run unless PROBE makes there new pistons with the 5/64 rings and two valve reliefs (supposed to be ligther) for a 4.280 bore and 3.375 stroke with stock rod length

He can get the same lackluster heads for less at a local shop with just a rebuild of cores he has, plus I wouldn't use 906's because of the open chamber design.

If you are starting from scratch as it sounds you are find some 915
heads .

---

Lackluster lol, maybe to a guy that already has or has had several 450hp plus motors but to most guys the results will be far from lackluster. There is always a better way to build a motor or a cheaper way or this, that etc.

My post was more or less meant to throw an idea out there. Not the ultimate B block 450hp build. Mine was more budget minded.

Aerohead will build 915s for 100 AND they will install better exhaust valves (for the nitrous) like some manley extremes for a tad bit more money too.

I put some 906 heads on my buddies car and they looked nice and performed very well for an as cast 906. Sure they didnt make 450hp but they ran well and the motor sounded good.

Next best thing would be 440source heads (budget minded) but they dont come with nice manley or ferrea valves. They come with ok valves. I also dont like the way the seats are machined. I know I have a set and had them fixed. Ended up being into them almost 2,000 dollars.

I was just throwing it out there (using a little nitrous)......... and to be honest with the nitrous it wont really matter what heads and compression he has when the button is pushed


Dan

Oh and nitrous does count! LOL how do you think the chevys keep up!!

hahaa just kiddin.

Dan you have obviously not seen the posts about aeroheads and their quality or lack there of , that is why I say lackluster , there is nothing special about what they do , just a standard valve job , and it's been said to not be very good . with that in mind , and core charges AND shipping half way across the country you can do better LOCAL .

906's with the open chamber are a BAD choice, I use them because I HAVE TO, not because I want to, so I have a lot more money tied up in cylinder heads than I really should.

I've got 3 pairs of 906's, one set pure stock legal ... $1200, one set with very mild port work that had been worked on twice because the first shop made them flow worse ... $1600, then a set that are a stage 2ish port job, that started off as a backyard template job that wasn't very good, $1500 ... If I had to sell them I'd be lucky to get 50 cents on the dollar for what I spent.

I have a set of 915's that will end up on the stock 383 once I get the pure stock bug out of my system.

you could pressurize the intake on a 383", use a creamy smooth cam and have plenty of streetability.....

I say get the source/edelbrock heads,have the valve job checked,and put springs to match the cam.
You havent mentioned the gears.That would factor heavily into the cam on a 383 build.Be pretty easy to get 425hp out of this with some good heads and still be smooth down low.
Even 400hp will be sweet.Build for torque,put some 3.23's in it and cruise.Will be a blast from a roll on the street.

---

Biggest factors ARE the cam/converter/compression and gears. The carb size is determined by a REALISTIC max rpm dictated by the combination.
