it was just a base 210 now its been re built, the heads have been modded they have 75cc chambers and had 1.72 valves now have 1.94. i bought the car with a 5 grand rebuild on the motor never been ran trust me i checked. this christmas i plan to get new heads and cam, the pistons are flattop alumnium. in about 3years i plan to build a 377 de-stroker but for what im using the car for now a high horse 327 will be fine.

I have an L30 Put in this cam last year. Very happy with it. Lunati #00016

Bracket Master II Chevrolet Small Block (1957 – Present) – The Bracket Master II Camshaft is the logical choice for some high performance street machines and mild performance Bracket racing applications. They provide excellent power over a broad power band and give that lopey idle so many people like. Hydraulic; Good idle. Good low end torque and horsepower. Works well with stock stall converter.

Advertised Duration IN/EX: 284/284
Duration @.050 IN/EX: 218/218
Gross Valve Lift IN/EX: .458"/.458"
Lobe Sep Angle / Intake Ctr Line: 110/106
Valve Lash IN/EX: Hyd/Hyd
RPM Range: 1500-5200

I had a 327 like you describe, mine was in a '64 Chevelle. I put in a Crane "Fireball" cam and man, that thing was terrific. I would power-shift at 6,500 rpm. It pulled good all the way to the red-line. This was 25 years ago, and I don't know if they still make that cam. They probably have "new, improved" versions of it though......

Man, cam selection is an art-form. The cam is the real heart of the engine, but it can't pump good unless all the other components are matched to it.

Cam selection is virtually limitless. For someone to make viable, realistic recommendations, you'd really need to post a detailed engine setup, the driveline setup, and your own expectations or desires.

For instance, I had the Crane Fireball cam in a '64 Chevelle, with 4.10 posi rear, 4-speed Muncie tranny, 327 (275 base hp) engine with the Camel hump heads, Edelbrock intake, Q-jet (race-prepped) carb, tuned headers, 10 to 1 compression. This combo worked real nice, but again, this was 25 years ago.

Bottom line: select cam carefully. If you install the wrong cam, it's very easy to end up with LESS performance than you had to begin with............

yea, most people love the lopey cams, like the 307 can be a great motor but u really need to steer away from the big aggressive cams. im gonna call the machine shop and see what all they did to it.

Call Isky and give them all your specs and what you are looking for. They will tell you exactly what to put in it. Great customer service.

75cc chambers on a 327 with flat-top pistons? This will result in less than 8.5:1 compression and will result in less than stellar performance with any cam that you might want to listen to at idle. What new heads are you planning to get?

I agree with Emperor, your best bet is probably to call the different cam manufacturers, give them all your specs, and see what they recommend. That should get you pretty close...................

Well, said. With small cubes, low CR, I would try and keep duration under ~260 (~210 @ 0.050) or it will be a dog on the street. A cam like this won't have a choppy idle.

I believe the listed compression ratio for 67-68 camaro with 210 hp 327 was 8.75:1 (1.72/1.5 valves, 75 cc chamber). The listed compression ratio for the 275 hp version was 10:1 (1.95/1.5 valves, 63 cc chamber). Did both of these engines use the same cam?

My replacement cam (.436 lift, 222* dur @ .050, 265* adv dur) seemed to add some pep when the engine was rebuilt.
