O.k. I'm sure this is a topic resurface over and over, but I don't have any info.

I was going to put a supercharger on my vette, but after reading about how dangerous it is for cast pistons, coupled with the problems I'm having w/ my engine, I might have to tear a lot off the engine anyway, why not just go all the way and pull the bitch out. I've got the hoist, stand, and truck.

I have all the info I need regarding pricing for supercharger upgrades, what are my options for a 383?

I'm in Chicago IL and I need to know who can do this and what the usual costs associated with this are. I understand that it has to do w/ the varying prices of parts such as Cam, pistons, heads, machining, rods, etc... but typically if I wanted to get about 450 HP out of it, what could I expect to pay. I just need to start with this general info to see what avenue is best for me.

Keep in mind I'm looking for that oh-so-sought-after "Pie in the sky" if you will, of lots of HP w/ all the RELIABILITY.

Thanks in advance.

:confused: :confused: :confused:

 

If you want a 450hp I would recommend a 383 with a Super Ram, 219 cam, AFR heads, exhuast. If you buy all new parts and pay for labor it will be over $10K. If you go for a forged shortblock route it will probably cost about the same with labor and the price of a supercharger and upgrades.

 

What are other good resources to start learning about this specifically?

I want to know what other setups people have used to accomplish this with regards to part numbers and such. Is there a company out there that makes specific kits? I know I could do the labor myself, but I just want to make sure I have the right combos.

 

Well you basically have two intake choices if you arent gonna put a SC on it, Superram and Miniram (lingenfelter.com and TPIS.com respectively). The 74219 cam is made for the SR and i believe the SR works best for an automatic or a 4+3. The MR i think is made more for 6speeds, and should be put with at least a zz9 cam from TPiS. Either will work well with a 383.

If you do decide to slap a SC on it, youll still need a rebuild to toughen the bottom up.

If you want more info, get Lingenfelters book "modifying small block chevys"

 

Excellent! Thank you much.

 

You're going to have more reliability issues with a supercharger vs. N/A (assuming you run decent boost), but you'll also make more power. I was making 470 rwhp w/a 355 and a 10 lb. pulley on the vortech, stock CAM, stock crank, forged pistons, hardened and polished stock connecting rods. I dumped the stock pancake Vortech intake and replaced it with a 3" pipe that netted me almost 14lbs. The car was kind of a POS, but I never had problems with the engine or reliability there of. You should be able to get a combo like that for under $10k and make decent power with decent reliability. I was running 12.20's at 120-123 on street tires. I could of made a lot more power with a cam and upgraded injectors (I had an FMU) but was pretty happy with the setup the way it was. I would recommend getting forged rods though just in case. You could come out cheaper just getting a 383 package and running NOS as well.

1/4 mile events go with a blower. Road course or other types of events go with N/A.
:D

 

383 stroker of course! :yesnod: :yesnod: i got mine (without intake,carb,oilpan,flywheel,starter,fuel pressure reg,higher stall converter,ect) for $4000.00. i have about $7000.00 in it now with all the other stuff needed to finish.check out http://www.allchevyengines.com. im getting the car back this weekend from install. im gonna post how things go. good luck. :cheers:

 

Go with the 383 make it totally forged then when that's not enough power for you, you can slap on a super charger or Nitrous. And you know after a little while that it's not going to be enough.

"Everyone has an addiction, mine is speed" :D

 

i didnt think you could run a sc on a stroker with all that cubic displacement cause the compression would be to high for the sc?

 

Go with a 383 AND a supercharger.

The compression ratio is what you want it to be. You can dial it back to 9 to 1 by biting the bullet and going to forged pistons with a dish, larger combustion chambers, thicker head gasket.

One of these days, I'm gonna do both. Check out Agostino's bolt-on packages when you're out shopping. http://www.agostino-racing.com

 

383 definately if you want reliability. Lingenfelter has some sweet packages, and you can bet your money that they know what they are doing. You can always add on to the 383 down the road also, if you put a SC on, your a little bit limited. Callaway's website might have some info though on SC's.

Its not the displacement that creates compression, its a combination of the pistons and heads/gasket

 

Thanks for all the input. Let me put an option out there that I've been thinking of and tell me what you think:

If I get a 383 right now and only put 9:1 compression pistons in it so I can eventually put a sc on it, I'm thinking it won't give me the power that I want right away for all that money it will take. What kind of HP could I expect from say, 9:1 forged pistons, 383 stroked and bored, 219 Cam, AFR 2.00 or 2.02 heads, miniram, approx 30# inj, and headers?

My thought is this, get the SC right away considering it will be at least a couple grand cheaper, run 6psi at approx 425HP for now, then eventually go with the 383 and put 9:1 compression right out of the gate, and then put the SC back on with a 10 or 12psi pully WOOOOOOOOHOOOOOOOO!!! Now that sounds like a better idea!

In the meantime while running only the sc, if I hurt a piston or two (with a properly dialed computer and only 6psi I don't see how I could do that) I'll just build it to a 383 and rock and roll.

What do you all think?

I already got some info, it will at least cost me around $5000 for a 383 and a lot more time doing it than the sc.

did I mention the reason I'm anxious is because I'm from Chicago = not many good driving days

:cheers: :cheers: :cheers:

 

Actually a Far West Suburb- North Aurora, I still consider myself a Chicagoan though, I comute to work in the loop everyday for the past 8 years.

 

We built an 8.50:1 LT1 383 for a supercharged application... Naturally aspirated on our engine dyno the thing still made a little over 400 hp. With a Vortech running 20 psi of boost, an intercooler, DFI, and race gas it made almost 700 at the REAR WHEELS!!!!! You cram enough boost or N2O in a Briggs and Stratton lawnmower and even it'll make some pretty killer power!!

Jeb, can you come over to Memphis and help me do a NO2 hookup to my riding mower :lol: Seriously, do you have a web site yet?

 

400 HP at 8.5:1.....wow, hmmm....I'm still thinking :crazy:
It seems that it comes down to current cash flow then. My inevitable plan is to do both 383 and s/c though, tell me what you think about my idea? I know you diehard gear heads want me to do internals, but I just don't know if I can afford the time money before next winter.

Lawnmowers and the more popular honda civic it would appear...ah, what's the difference, one just caries 3 more people :lol: :lol: :lol:
