That's the cam we put in the comet. Since the engine was vandalized, never got a chance to try it out. It sounded real good at idle and throttle response was excellent. It appears to be an excellent street performance cam. I'm going with a comp cams exteme energy series for the re-build.

Good Luck with CRANE! I personally would not run their product if it were free.I have similiar setup in the works.I am going to use COMP or possibly CROWER. The cam I got from Crane did not perform as I was told by their tech line and dealer. It was an Energizer. Maybe I just got the wrong tech from Crane.

For a hydraulic, I'd probably recommend the XE268H or the XE274H. These measure 224/230 and 230/236 respectively @ 0.050"

The XE268H will want shifted around 6300 rpm, the XE274H will want shifted around 6500-6600 in a 302.

Comp's power ranges are mostly geared for 350ci engines. Plus, for best performance, engines are generally shifted a few hundred rpm above their power peak. If you want the most power under the curve (and a good launch) stay conservative with cam timing.

Good Luck!

The XE274H is what I'm going with in the 331. From what I've been told, it rocks.

What do you mean by cam timing? Are you talking about the install of the cam + - on the gears? If so on the XE-274H how would you in stall it?

By cam timing, I'm referring to size.

I would install it between +2 and +4. Cams don't generally like to be installed retarded. An engine is a LOT more forgiving of a cam that is installed a little too far advanced, than of one that is installed retarded. Remember those smogger engines of the late 70's? They had their cams retarded to reduce NOx emissions. They were complete pigs.


I believe Comp grinds them 4 degrees advanced, so if it is installed 'straight up' on the timing chain, it is installed at +4.

Good Luck!

Think the 274 would be OK? Mostly street but will throw on some slicks and run it on week ends. How about gears I'm thinking about 26" diameter tires I have 3.55 and 4.57.

The XE 274 would be a good choice. I'm running one in my Falcon and it idles decent and has good power thru about 6000RPM.My Morris motor has an XE284 which is a little too big for a street car and I wouldn't recommend it.
