How much HP?

1967 camaro with 327 (275 HP). Has edelbrock performer intake,carter 650 carb, headers , dual exhaust and HEI dist.. I am assuming stock cam and pistons.

Are these add ons gaining me HP and how much? I am looking at buying a 383 that is advertised at 350 HP but I am thinking I could easily build mine past that for not too much $

What do you guys think?

Re: How much HP?

I think 350HP is pretty low for a 383

Re: How much HP?

a different cam and some good aftermarket heads will easily put your 327 over 35 hp.

Thumbs up Re: How much HP?

Jim is right.

Even with your medium valve 64 cc double-hump heads, no more than a CC 268HE or Crane/Cam Dynamics 272/272 Energizer hy-cam and a set of cheap headers will make it run like a "scalded-dog!!"...

Or install a CC 270S or Isky Z-20 solid cam and lifters and rpm her!!

I am assuming here that you are still at the stock CR. tho...

Re: How much HP?

First...If I were to go with the 272/272 Energizer hy-cam and 2.02 heads, what kind of Hp could I expect? And yes, the Comp ratio is still stock as far as I know...

2nd- What kind of HP would one expect from a prof built 383?

These guys are right...properly built 327 will run like a "scalded dog"

327 motor:

272 hy-cam, 650 carb., open headers and bowl blended 1.94"/1.50" valve heads, 370hp at 5500 rpm. 394t at 4000 rpm

2.02"/1.60" valves, open headers 388hp at 5500 rpm. 400t at 4500 rpm.
Both at 10 to 1 CR.

383 motor:

Like above. 384hp at 5000 rpm and 448t at 3500 rpm.

Now with; 280 hy-cam, 750 carb. and everything else the same as test 2 above;

404hp at 5500 rpm. 440t at 4000 rpm. Also, 10 to 1 CR.


And with a CC 270S solid cam and 750 carb;

406hp at 5000 rpm and 469t at 3500 rpm!

Now with a 280 solid cam and 750 carb;

428hp at 5500 rpm and 459t at 4000 rpm.

Hope it helps...

PS., Just by D2K is all so take it with a grain of salt.

And all of the cams lifts at .450" net lift except the 280's at .480" net lift to keep from digging them out of my cats is all....

Re: How much HP?

My 383--
Dart Iron Eagle heads- 200cc/64cc
Edelbrock Performer RPM Intake
Holley 750CFM Double pumper
Comp XE274 Cam
Hooker Super Comp Headers
10:1 compression
Dyno highlights:
RPMs HP Torque
3000 239 416
3500 290 432
4000 331 440
4500 370 430
5000 404 424
5500 415 396
As you can see its a pretty flat torque curve which i feel is the big advantage.
Not trying to sway your decision, 327s are great motors, just giving you info for an informed decision.

I was thinking the same thing. It kind of defeats the purpose of having a 383.

That 383 is weak! If your only going for 350 hp? You can easily get that out of the 327. But I would rather have a stout 383 over a 327. If I had the choice of building one or the other, I would go with the 383.

Re: How much HP?

kinda wondering exactly what you're after, too. Anything beyond (basically meaningless by themselves) numbers? What do you need it to do? How will you use it? How is your present combo not "meeting your needs" (pardon me for such a pc phrase)? What's your goal and How much do you want to spend on it?

Re: How much HP?

My car will not be a daily driver but used for cruise nights and weekend fun. I would like to be able to take it to the track also. I am looking to get into the 450 hp range....

I'm sure you could get there with a 327, but it would be a lot easier with the 383's extra cubes.

Smile Re: How much HP?

The guy I bought my car back from had the 327 in it that I gave my Nephew that was made just like I mentioned and he said he had a 12.9 second, 1/4 mile strip slip from a South Cali. Drag Strip somewhere using NO more then a small set of real slicks!

Motor was a rebuilt, .040" over, 300hp/327 with a Holley 1850, 600cfm carb on a cheap aluminum adapter and a stock, cast-iron AFB intake, the Crane Came Dynamics 272/272 Energizer and a set of cheap 1.625" Hooker Headers and small blown-out, worn-out Turbo's! Heads were 1.94"/1.50" double-humps with a point distributor with a see-through cap!!

I figure she was right at 10 to 1 CR.

M-20, 3.31's too! BUT my car is an early, Dec. '66, '67 car so I figure it is LIGHT!!

AND I know it ran hard before I pulled it to make way for my Strong-Arm 406 SB so I had NO reason to doubt him!!

I am saying that a 327 can be made to run like a 12.9 second "scalded-dog" with not much done to it if it is up around a stock, 10 to 1 CR. to begin with!!

GM got the litte sucker just about dead-nuts right when they made the hi-po 327's!!

That's all..
