Re: building 327

That sounds like the same spec as the Edelbrock performer cam. My 327 is running the CS-1014 same spec with 112 lobe sep. It's really just one step above stock. Better with good heads and headers but not a bad little cam for a street car. Pulls 18 inches of vaccuum or more. Search on performer cam or CS-1014 for more info.

What is the duration on that cam ? With only lift numbers, it doesn't mean anything.

Re: building 327

Which 291 heads are they? The later version had smaller ports and 76cc chambers. 76cc chambers and flat tops in a 327 ain't good... Do they have accessory holes?

I think that date code says May 24, 1967.

I would go with a little more cam than your original choice, as Tom suggested, as long as you have decent valve springs. The good old Comp 268H (not the XE) would be another choice. If you have stock springs that are old and worn out you may run into coil bind with anything much over .450 lift. Some cheap Z-28 type springs would be an inexpensive upgrade.

Do you have a stock torque converter? Power brakes? These are also things to consider. Too big of a cam and you'll run into problems idling in gear with a stock converter, and brakes that don't get enough vacuum to work correctly in traffic.

Then again maybe you have considered all these things and that's how you arrived at your first choice...

They have a smaller voodoo also, the 60100 cam is quite similar to your 1st cam you were looking at. I would not worry about low vacuum on any of theses cams. They are not very big. I would keep it smaller using those heads though. Those heads are good to get your compression up, but they are not going to breathe very well. (small ports) If you put too large of a cam in it, it will feel like you are hitting a wall and it will not RPM. If you stay smaller on the cam, it should RPM to the moon ! I would go 262 max.

Re: building 327

The good old 268 he referred to will get you more than enough to run power brakes, probably 13"-18" of vac.
Some of us only have 6"-8" of vacuum and still run power brakes.
268 is a great cam for a stock-ish 327... If the heads are the huge 75cc chamber smog heads with 1.72" valves, I wouldn't do anything to the motor until I could replace the heads with something at least decent, like a double hump, vortec, anything but the 75cc heads really.

The only Mustang I'd ever own is a Fender.

If all you're looking for is a little more than stock and don't want to have to mess with changing valve springs, then that cam should work well for you. If you had a 4-speed and a little more rearend gear I would definitely step up to a little bigger cam though.
