11 or 12 second 327 combo!?

The 327 is ancient, and I'm sure many of yal have accomplished those times, just curious what was the combo, gearing, car? Was the car street driven or all out race car? Just getting ideas guys would greatly appreciate it, plus I love hearing everyone's story's on how this combo worked out or how this did that, cool stuff!

Havent personnaly went that far with a 327 but i did have a freind a good many years ago had a 327 in a 55 chevy that was dead into the 10's.

This was before serpetine belts and the engine would toss all the belts off everytime you spun it to redline which was around 9k rpm. This was a full out race engine but he drove it around on the streets. Usally came out after dark. If you get my drift.

Sell the 327 and Replace it with a nice 383 or 406. This will have much better street manors and alot easier tonreach your goal. Also much cheaper. 11 second 327 will need some cash thrown at it. 11 second 383 just needs a good cam and a light car with some gear. Of course ita never that simple but the 327 would be an involed project and a costly one.

A 3500 pound car will run high 12s with just over 400 hp

so figure out what your car weighs
figure out how to make that much power from a small engine
bolt it together with proper matched driveline
bolt of some sticky tires
find someone(you) to drive the car like you stole it

what kind of car/weight are you working with,lets do a few theoratical combos

Hcompton, I have 3 327's so I figured why not? I'm also building a 406... Vinnie the car is a 55 Chevy 2 dork sedan roughly around 3300 pounds. It has a 355 with vortec heads a small cam and a dual plane with a 4 speed, the car is a project body wise so I have yet to try that combo out, I just thought I would do something different with a 327.

Steve Erkel used to drive a 1 dork sedan,lol


Back when I started to play around with cars,a local gas station hired me.There were 7 57 chevys there most of the time.Both owners had 327s in their cars.
Mikes car had a z/28 intake 650 double pumper,hydraulic cam,think it was a sig erson hi flow II,11:1,turbo 400, 4.11 gears,later changed to 3.36 gears.
car ran 14.2s
The other owner,Kerry,had a single plane intake,(think it was a torker)750 double pumper,solid lifter cam.11:1,muncie wide ratio.
That car ran a best of 13.5
this was a long time ago

You can make a very good 11-12 second pump gas 327 by supercharging it.

the 327 engine is idea for the 142 Weiand blower and the 177 Weiand blower.
The engine is very simple to build. A low engine compression ratio is key.

You don't need a 383 or 421 SBC.. When you can supercharge a 327.

500+ hp and a ton of torque is easy with a Weiand blown low cr 327. Just right for a 55 chev.

The blown lil pump gas 327-500+hp eats all "strokers"....
and at a fraction of the price.

My bad auto correct on my phone sucks, ment door lol, good ole days probably camel hump headed, that turbo 400 probably slowed that car down a lot.

And f bird 88 that's what I'm thinking, low cr ratio 327 with a 177, the question is what kind of gearing? And should I keep the 4 speed?

forgot all about the heads,it was awhile ago.
The 14 second car had 1.94s,pressed studs,hydraulic cam.
The 13.5 car had 2.02s converted to screw in studs,no guide plates,both were camel bump heads.
My 67 Camaro started with camel bump heads.There was not a lot to choose from back then.

If you have a large journal 327 it will take a 350 crank so making it a 383 should be just as doable as a 350 block. If you have the cash I would supercharge the 327 as said above.

Sounds like my dads old combo, never new what it ran, but it was a 331, 11:2:1 cr, crane solid lift cam with a ton of duration my dad doesn't even remember the specs, a set of camels ported by his buddy, had the 1.94 valves, also had tripple springs, and screw in studs, no guide plates, stamped steel rockers, edelbrock tunnel ram with two 600 holleys, Muncie 4 speed and 4.88's. Like I said didn't know what it ran but it ate a lot of big blocks on the street, I have a picture on my wall of him yanking the drivers side front tire off the ground about 6-8 inches on some n-50's I would of loved to see what it would of done with slicks, but that was way before my time, my dad was just a broke full time college student like me at the time lol. The car was also a 55 Chevy.

You need a 3.75 stroke crank to make a 383

Yes a 6-71 with dual 750 afb's will be very cool and make huge street power on a 327.
Just another way to skin this cat based on your blower preference.
All are do able. Not that big on the 4-71 blower, myself.

"4 speed" this motor will eat a th700r4. This is no wimp 327.

4 speed manual trans yes, with bonus points.

Gear as required based on engine horsepower and tire size and car weight and desired effect.
