It needs to be faster.

The 67 needs to be faster, i just don't feel it pulling like it should.

It has headers, a cam of some sort, im not sure what though...

Im basically at zero, any suggestions other than twin turbo or supercharging, to get this beast fast as all hell?

Since you want it to be really fast, your gonna have to pull the engine and have it rebuilt to specific specs. You didn't mention all the parts it has other than headers and carb so I am assuming you pretty close to stock or just a bit higher. If you want to put some power to the ground properly, have the engine built to put out what power you want. You'll probably need aftermarket heads. There are engine builders that sell complete engines that make around 450 HP and sell for under $4000. That's expensive but HP isn't cheap.

Or, rebuild yours to low comp. and ad a supercharger or turbo system.

Your options are endless !!!

Really need to know the cam specs, which heads, stall on the converter. If you have a big cam in there, stock smog heads, and a stock converter, it will be a dog.

The smog heads will choke off things right when a big cam starts to get into into it's power peak (plus kill compression with the big chambers), while the big cam kills low end torque, which combined with the stock converter, results in blah acceleration.



Heads along the lines of TFS 23* units, a cam like the Comp Cams 268XE (or maybe the 274XE), and a 3,000 stall will get your 67 into the low 13's/high 12's.

If that isn't enough, you need more cubes or a power adder.

Thanks for the info, its actually a newer engine but i haven't been able to pull the vin off it, and i really do need to open it up and see what it has in it, it does have a stall converter, when i took it into the shop, i think he said it was set at 6000, ill start shopping sround for new heads and a cam, any info on what kind of headers, pulleys, anything else to get it up smoking. What about getting it stroked?? and from what ive been told getting the gears set up in the rear may help as well, advantages to 4:10, disadvantages??

And my ultimate goal is to one day have it twin turbo, i am but a lonely sales boy at comp usa, so it might take a while. actually it will probably take forever.

if it dosent have much of a cam throw that 750 away go to a 600 or 650
you are over carbed for a 350 with not much done its a classic mistake

disadvantages to 410 gears is basically gas mileage. if u are gonna use this car for a daily driver then that is gonna kill ya

the 410 gears have nothing to do with it
how cares about fuel milage :confused:

It actually has a lot to do with it. If you're crusing at 3000 rpm vs say 2000 rpm, you're going to use more gas. When I switched from a TH350 to a TH700R4, I literally doubled my gas mileage. And I only have a 3.42 axle ratio. Granted some of it was from the new lockup converter, but a lot of it was simply due to a lower cruising RPM.

he is asking about more power not fuel milage i didnt build my Z28 with gas milage on my mind i wanted to go fast so i built it that way

im asking for suggestions.

my suggestion: Crate engine. Then have your tranny built. make sure you know your cam lobes. And finally a rear end......

Save your cash and then get one of these...

mmmm sexy...

I would get a set of sportsman2 heads 2.02 and a .600 lift roller cam and some eagle rods and eagle steel crank and some je pistons a 150 shot of nos and you will be in the 10's and still be ble to drive it on the street.

So when i do decide to get the new heads and cam and rollers and what not, will that make the 750 a little less useless?

You'll most likely have to rejet the carb and change the springs in the distributor. Honestly, set a goal for yourself or you'll just keep spending and spending on things you don't need. :)

yeah right now i just think im going to get it tuned, theres just a lot i have to do and i have trouble wraping my head around it. I will go with a new set of heads, but i have no idea where to start, new cam, new rockers and rods. New water pump, pulleys, alternator, distributor, coil, ignition, inner fenders...

I just looked at wheels and tires, and that at about two grand, for the torque thrust 2 classics, that should accent the flat black real nice, especially after all the body work.

Theres just so much.

They even look good on the new stuff. :)

:D I agree those wheels look good on that 4th gen...
I think they'd look good on a Z28 aswell

I run a 750 on my 69. No complaints. 8.209 in the 1/8th with 1.84 60' time

that makes me feel better about that purchase then, i just have to get it tuned and jetted and i should be good.

not realy get rid of holley

Yeah get it tuned first and go from there. The Holley 750 VS carb is fine, don't waste $$ on a new carb. Down the road upgrade to a 383sbc or if you can find a good 400 block, build a 406sbc. Purchase the best set of heads you can afford ( 195 cc+ AFR, Trick Flow etc.) and match a cam, intake, carb, stall, gears, etc. Then work on setting up your suspension, sticky tires, etc. It's only $$ after all! Have fun!!

well im only going to put the best parts on it, even if it means waiting to save the money, i want it done right, and this message board is deffinatly an outlet for making a badass camaro.

I'd leave that motor in it for now and start accumulating all the parts for a complete new motor. When you have everything, assemble it and swap motors.

I'd HIGHLY recommend a 406 with the best heads you can afford.

Any ideal of what times your currently running? It would be nice to have a basis to start with. There is always the 150 hp the easy way..........NOS. But it wouldn't hurt to have some forged pistons in there.

You can give us a call and we can work up some different packages for you. Depending on how fast you want to run we have a few different packages.

Thanks,

At the moment its sitting, i got pulled over, and the police told me they would give me a ticket if they saw me drive it again, long story short, i need new headers and exaust first... i guess its just a little too loud for them.

As for what times im running, i have no idea. havent been able to bring it to the track yet, but if i were to guess i would say low 13's high 12's???

And ive decided i don't want to do nos, i just want pure unadultarated power.

But as far as a build up i will keep you guys in mind too, getting new heads, pistions, rockers, cam, get it ported.

It will be a while, but thats what is going to happen first and foremost.

Well that sucks, getting pulled over by the cops! :death: :death:

You say your car right now is running low 13s, high 12s....well that's not too bad considering your car would need to put down around 300 RWHP (or close to it) to run those times. That is alot more power than a miild 350 would do. Maybe your under-estimating what you have now.
Either way, you need to open that engine up, find out the condition of the internals and what the compression ratio is and what cam is in there, etc.
As stated in a previous post, buy the best set of heads you can afford then match the cam and compression to head flow data (don't forget about stall speed and gears and etc).
You asked about a stroker...It's really not hard to build a 450HP stroker (383-385). Major ingredients....10.5:1 short block, medium sized cam (230ish duration), and a good set of heads (Pro1 or AFR or Brodix are the only ones I would use) will get you close if not more than 450.

Good luck with your decisions... :D

Low 13's, high 12's is damn respectable if those times are accurate. Many people overestimate what their car runs (and what it has for HP). It seems like everyone I run into says their mild 350sbc has 400+HP and runs 12's! :rolleyes:

Get it to a track and see what she does. Good luck!
