I have a 327, muncie with 3.02 gears. Im looking to completely rebuild the 327, and don't have much experience doing so. I am thinking of setting it up for 7000, maybe higher rpms. Just wandering if you guys could shoot some nice setups for me to think about, I am not to good at picking things out that will all work together well. Thanks for any help.

why the 327? originality? why not a 350? more cubes and probably cheaper to build.

Your gears will need to be lower for that 327 to work well IMO. What are your goals? Street car? Race only? What weight is the car? What engine parts do you have? Wide ratio or close ratio Muncie? I've never heard of 3.02 gears, 3.08's maybe?

Just a ?, But why so many RPM's? are you keeping this a street car? Not saying its a bad idea, just more expensive to buy reliable parts for that kind of RPM. You alo are going to want to get light weight parts, thats alot of weight otherwise to be slinging around on stock rods and such. Have fun, JEFF

If you want to make a quick car with a 327, build it to work from 3800 to 7000 and gear it accordingly. It will keep up with all the 350s quite well. It will be a compromise for a street engine though. Idling somewhat rough, hopefully having enough vaccum for power brakes, AND the engine has to be built with precision and care to ensure a long life.

Or buy a cheapo 383 and "mothball" the 327. You'll be able to make as much power at lower rpms with the increased displacement. Easier on parts, less troublesome driving, etc.

However, if you want to be different, nostalgic, etc, then many here have built STOUT 327s and will share their advice. Old fashioned stuff revolves around cam and compression, so give it plenty of both, ( small on the cam though) and you'll be happy with the power.

Don't know if you'll like the 4.56s it wants, but hey... tongue.gif

If you're willing to give that short stroke motor the gearing it needs, then I have no doubt in my military mind these guys will fix you up with a known, proven combo.

In addition to the gears, are you willing to set valve lash periodically, i.e. use a solid lifter cam, or should it be "low maintenance" hydraulic?


You gain BOTH driveability and rev-ability with a solid, but its more of a hassle to set lash periodically ( esp on a 7000 rpm motor).

So set out to define what you're looking for, and how much of a compromise towards unadulterated power you are willing to make!

Let's hear your goals for this engine first. That will enable us to recommend a better combo. Several have already asked what you want to do with the engine, and that is THE big question. Following that plan will ensure that you are happy with the results.

Do you want as racy an engine as possible?
Do you want a *serious* street engine?
Just a stout cruiser?
Do you care about gas mileage?
How about daily streetability? Does it need to be reliable and low-maintenance enough to be driven regularly or go long distances at the drop of a hat?

Let us know some of your thoughts on this and we can fill you in on the rest.

It will be driven not every day, but on weekends probably. I want it to be serious street machine, but not so racy that I have to do something every other time I take it out. I will probably be going on a few long distance trips throughout the year to shows. As for the muncie, I dont know the gear ratio for it. I figured I would have to change out that rearend for this motor(the guy I bought it from said 3.01, but someone else told me probably 3.02..so who knows). I was also looking to supercharge it with maybe that vortech super charger? I figured a solid cam, the lashing I dont think would bother me to much. I decided to stick with the 327 because I have been told by many that a 350 wouldnt be able to compare, if I built it right. Hope this helps.

I decided to stick with the 327 because I have been told by many that a 350 wouldnt be able to compare, if I built it right. Hope this helps.One of the biggest myths in Hot Rodding. All else being equal, a 350 will ALWAYS make more power than a 327. Cubes are where it is at if you are looking for big power. There is no magic in a 327 combo.

I plan to build a 327, because my short block is sound, and it is in my car. However, I would be kidding myself if I thought that a 350, 383, or 406 would not make more power for the same (or likely less) money.

Best of luck with whichever way you decide to go. smile.gif

The best all around 327 motor was the 327/350HP motor. 11.0/1 CR, 2.02/1.60 Valves, Hyd flat tappet cam 222/222@ .050 .447/.447 on 114LSA. Same motor with the soild cam was a 6500 RPM screamer rated at 365HP. Run either of these with a 4.11 rear and shift away.

So say I set it up like the previous post with the solid cam. Would that much compression be safe with the supercharger? I do not know a thing about them.

I have a similar question...I am just starting to scope out and budget an engine rebuild for my '65 Chevelle convertible. Engine is a bone stock "66 327-250hp with the exception of an Edelbrock EPS manifold, Edelbrock 600 cfm carb and Mallory HEI. Now, I am going to rebuild this winter and here is what I am thinking....

Stock Crank
Keith Black Silvolite Flat Top Pistons (9.5:1)
Stock Connecting Rods
Edelbrock Performer RPM Heads (#60899), 64cc, Straight Plugs
Comp Cams XE268H Camshaft (224/230@.050, .477/.480)
Re-use Performer EPS
Re-use Edelbrock Crab
Re-use Mallory HEI
ARP Bolts
1 5/8" Heddmen Headers

Any body have any comments on the setup...anything I missed or should look at as an alternate? This is my first total rebuild so I would like to hear any input you guys might have.
