I bought a 327 some time ago and just havent had the time to mess with it.It was a friends that came from a running car. he upgrade to a b/b. Until now all I knew was that it was a solid lifter cam engine with world heads, 7quart pan with a single plane, I think a torker? My buds were telling me it would work rather well in my 57 210 because I have a 4-speed with 3:73's. I pulled the timing chain searching for numbers to id the cam. I came away with a grind number of 300b-6. A quick google bought me to comp cams were I was able to print a spec card. Here goes:
dur @intake 300, ex.314
duration @.050 lift:in265 ex276
My questions are:
1.) will this set-up work for me?
2.) what type of power/horsepower am I looking at?
3.) What type of carb should I be looking at?
Currently I am running a mild 350 (260hp) @ rear wheels. I have 3/8 metal line to mech. pump then -6an up to carb. I was planning on swapping out the 350 in october since the 350 runs well and dont want any down time for summer cruising. The 350 leaks a fair amount of oil. Due to sloppy gasket placement of gaskets by p/o 15yrs ago or by time and abuse. Either way a change is a brewin"!
Any thoughts, pos. or neg. are welcomed. thanks in advance for any input

In my opinion, that is an awfully big camshaft for a streeter, and if it were mine, I would go for a hyraulic lifter cam around 220 degrees duration @.050. I would also get rid of the single plane manifold and replace it with an Air Gap Performer.
A 750 carb would be more than adequate for a 327.
These changes will add a ton of bottom end and make it a whole lot easier to live with...My 331 with a performer RPM, 750 Edelbrock carb, 461x heads, and an Isky 280 cam made 373 horses on the dyno at about 6200 RPM. Torque was something like 310 ft lbs. In a 1650 pound car, it was a hoot !!!

I really didnt want to mess with the internals. I figured since I was running non power brakes and since it was a stick car this set-up might work. I have a dual plane on the 350. Should I use that instead of the torker single plane? What about carb?I have a 4150 mech. sec. holley (750) lying around. Maybe I'll use that. Should I contact holley for advice on power valve/jet set-up?

That cam will not be happy in a street car, and 3.73's are not steep enough to get it going. An Isky 270 mega cam would be perfect for your setup if you are around 9.5-10:1 compression. You didn't mention your heads or compression ratio so I just assummed flat top pistions and 462 camel hump heads.

they are world heads. I know nothing about them as well. I'll start looking into what they are this week. So this set up is a bust? Is this yet another boat anchor in my garage?

Not a boat anchor. Just a bit hot for the street. A moderate cam swap and you will be styling for the weekend cruise.

I think he should know what the compression ratio is before suggesting cams. With a cam that big it might be pretty high and a modern cam will make way too much cylinder pressure My 5¢.

If they are World heads, chances are they are S/R or S/R Torquer heads which have either 67 or 76 cc chambers. That is a significant difference so you will need to determine which you have before you go any further. In case you do not know how to do this, get a piece of plexiglass large enough to cover the combustion chamber, drill a hole in the center, run a small bead of lithium grease around the edge of the chamber and push the plexiglass into it to stick it down. Level the head. Use a syringe to fill the chamber with water or alcohol up to the bottom of he plexiglass. The number of cc's will tell you which cc chamber you have.

sorry to butt in but one can use anything flat that will adhere the same and just fill to the bottom of the hole. the plex just lets you see it (liquid ) rise

What is the full CompCams P/N?

Even taking into account that duration of a solid lifter cam is actually a little lower than advertised (due to valve lash), that's a lot of cam for the street and will work well only with the proper heads, high compression, and a lower rear axle and/or first gear.

I'd say shoot for something in the range of 220-230 @ .050" lift, assuming 9.0:1 - 10.0:1 compression. And I'd certainly go through the engine completely while it's out of the car.

As a 327 owner, I can tell you those little motors are a lot of fun with the right parts and gearing, but have to rev another 1,000 RPM or so to make power comparable to a similarly-built 350.

You could call World Products and ask what heads they are.

WORLD PRODUCTS

If they have been decked at all, CC'ing will be the only way to tell what the combustion chamber volume is.

From their Faqs page:
Which cylinder heads do I have and what are the component specs for the valves and springs?
All the heads we make have cast-in letters and codes under the valve cover. It is important to note that World is not affiliated with Dart or Roush although very early castings may have some of these markings. When calling customer service, first reference the markings on your head. A code such as "I-037 ” or "WOR-070B" determine the family of head. Ford iron heads have Windsor (200cc runner) or J/R (170cc runner) cast in place. The numbers stamped on the end pads of a head are the abbreviated World part number. If the spring and valve size/type is desired, you must first measure the diameter of your spring and then the World rep can provide more complete specs. We cannot determine the chamber size by any markings so that must be measured by the owner.

I also have a 327 with world heads that I purchased. I have "S/R 1-052" stamped between cylinders 5/7 on mine. I called world products, but they couldn't give me a whole lot of information. The engine runs good, so I sure don't want to pull the heads off to find out. Anybody out there have any ideas?

TIA. Brian

what would happened if I choose to install as is? Will it not hold a idle? I'd have to rev it out much higher to make any sort of power?

I think it would idle rough, suck gas, and be flat on the bottom.
