I want to build the fastest C3 possible for strip and street. Need your help.
Currently my 76 has 383 stroker, TH350, 3.55 gears.
Yesterday I got my best 1/4 mile at 13.9 and 98 mph.
I am prepared to do whatever it takes to make my car faster.
The engine I have now would not last on nitrous so that is not an option.
I am willing to build a much better 383 or 406 that can support NOS.
For a tranny I'd like to go 700r4.
Can a 700r4 handle 500hp plus 150 more juice hp?
What mods do I need to do to my drive train. All I have right now are high strength solid u-joints throughout. Tires right now are sticky bias ply street legal strip tires.
Any and all info would be appreciated.
Web sites or e-mail addresses of people who have done this before will help too.
Thanks.

How much money are you willing to spend. Do you want to go 12s or do you want 10s. Some here are running high 10s low 11s with a IRS rear. Any faster probably a solid axle should be installed for realiabilty. If you want to go real fast why not build up a 540+ ci inch motor and go 9s. It all depends on how fast you want to go and how much you are willing to spend and do you want it streetable.

Like others have said, "How much money do you have?" :jester
Plan on spending 20 g's to build a low ten second street driven car. 10+ thou for a built big cube big block, 4 thou for a 4l80 tranny that will take all the abuse you can throw at it, 6 thou for http://www.tomsdifferentials.com best rear end parts. Throw in another 5 grand for incidentals (better rad, etc.), and you will have a daily driveable 10 or 9 second capable car (with slicks). :eek: :cool: :D :cheers:

Re: I want to build the fastest C3 possible for strip and street. Need your help. (Gordonm)
I want to run in the 11's.
I would prefer to do it with a small block 383/406.
I want to be streetable.
I will consider a solid rear axel. Has anyone done this swap?
If I stay with IRS what up grades are needed?
Keep the suggestions coming. A bit of good info here.
Thanks.

Can you describe your 383? what heads,cam,carb,compression,rod length,total timming. Based off your ET/MPH, I guess it's got issues. I would think for alot less money mentioned above you can make it a solid low 12/upper 11 second car.

Re: I want to build the fastest C3 possible for strip and street. Need your help. (John Dirks)
i'm surprised you're running an almost 14 sec pass with a 383-- what is your combination? something must be off.
anyway, good luck on trying to get "help" about being the fastest C3-- ALOT of people are in that quest, including me. :)
but $20K for 10 sec-- seems a bit too much-- there's plenty of street cars around my area that are running that, and they definitely don't have that much invested. IMO-- don't go the solid axle route-- it's not really a corvette anymore with a solid axle- you might as well go buy a nova or camaro.
you might want to consider lowering your C3's weight--- that's the biggest factor holding you back. drop that fat whale down to 2600-2700 lbs, and you'll see 11's easily on a decent 350.
BTW,, back in the early 90's there was an articae in a super chevy or car craft mag that had a C3 twin turbo BBC with a 9" rear--- ran 8's. i'll see if i can find that issue.. i have it somewhere.

Re: I want to build the fastest C3 possible for strip and street. Need your help. (blue_stingray)
I was just replying to the title of this thread. He did mention the fastest possible C-3 for street and strip! I didn't even mention turbos!
When I said 20 g's, I wasn't going the el cheapo route! The car I envisioned would idle well, be very streetable, able to run a 4:11 rear gear in overdrive without revving the heck out of the engine, and be reliable at the high hp levels required to run low tens/high nines. That's tough to do and remain streetable. I never did mention gas mileage though! :jester :lol:
Sure, you can build a ten second C-3 for less, but be prepared to break parts, and stretch the limits of "streetability". :crazy: I would be leery of trusting 25 year old driveline parts to run even 11's. For the cost and hassle of going to a straight axle, I would buy a 12 bolt conversion from Tom's, and the heavier half shafts, side yolks, and spindles. To run lower than twelves legally, he will also need a six link and a cage. Also slicks, halfshaft and driveshaft loops, scattershield or tranny blanket, dual three inch exhaust, all new rear suspension (offset trailing arms, rod end camber rods, poly diff mount cushions)etc, etc. See, that's where that extra cash will come in handy. Trust me, I'm on the way there, and I know how much money I've spent. And I'm only in the twelves so far (at 3600 ft and mount Everest air).
I also agree that your current 1/4 times are slow with your combo, although the high altitudes in Alberta add almost 1/2 a second over sea level (at least in Calgary).

With a 383, you should be able to get into the 11's with the right combination. Purchase some Brodix or AFR heads, have your favorite head porter clean-em up with the goal of 290/210 flow by .600 lift. Invest in new valvetrain, good hyd roller cam in the range of 225-235 duration @ .050, Victor single plane manifold, 750 cfm holley, 3500 rpm converter and 3.73 gears, sticky tires, keep raceweight @ 3500 or less and with a little dyno time making the tune work, you should have a 450 hp motor that will put you into the mid to high 11's..... but I dunno.
As a note, if you have cr up to 9.5-1 to 10-1 should be sufficient and your short block components, whatever they are should live a long life provided you keep it under 6500 rpm and lay off the Nitrous.
The heads are probably in the $ 2000 area after porting, everything else shouldn't be over another 2-3 thousand total.
good luck

Re: I want to build the fastest C3 possible for strip and street. Need your help. (John Dirks)
There has to be something wrong in your combination to go only 13.90's...
What is your altitude?
My original combination went 12.88's, that was with a .040 over 350 and the addition of the Holley Systemax II package which I purchased for $1,300.
The package includes aluminum heads, intake, cam, etc. ...everything you need from the short-block up except for the carb and distributor. I added headers and a Holley 750 vacuum-sec. carb. If you wish to discuss more (including tranny and rear upgrades) give me a call (503) 447-5724. Deen
P.S. A stock engine will easily handle a 100 HP shot of NOS

Re: I want to build the fastest C3 possible for strip and street. Need your help. (Wt99C5)
I will post the rest of my time slip as soon as possible.
Elevation is high here. Even the really "worked" cars around here are not pulling amazing times.
My TH350 is definately holding me back. It is very sluggish shifting.
An above post said to lighten the car to 2600 lb range. Is that even possible?
My 383 is quite mild. Vortec heads, Edlbrock rpm intake, Edlbrock 750 carb, ZZ3 cam, MSD, headers, 2 1/2 " exhaust, hypertectic pistons, stock rods, etc.
Thanks for all the info.

BTW, not mentioned on this site is the fact that the complete removal of your front sway bar for drag racing will eliminate 12.5-13 pounds right off the bat. No, you won't notice any handling changes on the street.

I agree with other posters...I think you can get more out of your current configuration. Good luck!

I've got mine down to 2800 lbs. (dry) and it still has all original glass and a full interior including power seats & windows. That's about all though!

Re: I want to build the fastest C3 possible for strip and street. Need your help. (The Dude)
The only question I have is do you want the car to handle or not? Going fast in a straight line is pretty straightforward. Either add cubic inches, lose weight off the car or both. Everytime you add more power, you will need to add some strength as well...

Care to share some weight loss secrets? My '76 tipped the scales recently at 3,600 with me in it. And I only go about 203-206. I'm about to attack the sound deadener installed under the carpet, but ideas that don't involve Plexiglas and/or cutting torches are always welcome.
My car weighs in at about 3200 with a little gas in it. I too would like to know how to bring the car to only 2800. Thanks
