I am looking at replacing my rv cam (melling #1730) in the 327,engine is in my 69 C-10 SWB.The motor came from a 63 Impala,I have put 202 Camel heads(light ported)#461, a Edel. performer and edel. 600 carb.Hei,and Hedman headers.Trans. is a TH-350 with a 2k stall and 3:73 gears.Comp cam suggested the XE-268, a friend of mine thought it might be a little to much what are your guys thought s on it would the XE-262 be better suited for this?I am not sold on a Comp cam have looked at the Lunati Voodo cams as well as a millon other,just thought I would ask you guys .Appreciate all the help and advice from you

don't know the number, but speedpro i think sells them as does napa. it is the L79 hydraulic cam. better torque than the 097 and 30 30 cam but does not wind as high. i loved the L79 engine. jim

I belive the comp.ratio is around 9.5:1 and tire size 28"tall 275/60/15.I only have about 421/443 lift 270/280 adv.dur. melling rv cam.in it at this time.It gets great mpg but I am willing to give up some for some hp/torque.I just want a fun little truck with a little more lope.

I don't necessarily agree that the XE-268 would be a little large for your 327. It works great in a 350, but it is pretty mild. I like Lunati's Voodoo 60102 cam much better: 219/227 dur @ .050, .468/.489 lift, ground on a 112 deg. lobe center. Similar specs to the XE-268 but it is not as hard on the valves. It is a later development by the guy who designed the XE series for CompCams. If you are afraid it is going to be too big, you can always go with an XE-262 or the Voodoo 60101 cam. You can see the specs for the 60102 here:

Be sure to use the recommended valve springs with it.

I have a voodoo 60101 cam in a 327 installed in a Jeep. It's a nice responsive cam. Idles smooth and sounds nice. No problems idling in gear with the automatic. I also have 3.73 gears and a 2000 stall converter. Pulls good with 35" tires. If it was two wheel drive, I would have went with the 60102 cam.

I had asked comp and lunati what they recommened and comp was the xe-268 and Lunati was the 60102.My motor was redone a few yrs back I would say I have about 3-4 k easy miles,the machine shop said I could easily go with a 500 lift on my springs.

The Voodoo cam (ground on a 112 deg LSA) will give you a better idle and more vacuum at idle. It will also lower your chances of engine knock and move your torque up to work better with your torque converter.

The CompCam will give you that nice choppy idle.

Hard to beat the Lunati Voodoo cams recommended above, but I doubt if either will have much of a lope. Same goes for the Comp XE268.

Lope is typically a function of overlap, the period when both intake and exhaust valves are open. You can get more overlap with more duration or a tighter LSA (lobe separation angle). If you have 4 different cams with 268 advertised duration, the cams with 112 & 114 LSA will idle smoothly, the one with 110 LSA may have just a slight lope, and the one with 108 will have a more noticeable lope.

I think this Isky cam will give you a nice lope without going overboard on duration and killing your low-mid RPM torque.

The tight LSA will concentrate power in a narrower RPM range, which means it will have a strong mid-range hit. Perfect for your 3.73 gears and 2K converter. You should check with Isky to see if it will work with your compression. I didn't look at the timing card, but it will close the intake valve sooner than a 110 or 112 LSA cam, which means it will make more cylinder pressure.

I'm running the Lunati Voodoo 262/268 cam in my 385 stroker. I wanted a cam that worked off idle to 56/5800 RPM's and made good low end torque and mid range power. It works great. My engine pulls 20 inches of vacuum at idle and 17 to 18 inches at regular cruise speeds. The idle is pretty smooth. I've never used it in a 327, but it's an absolute stump puller in my setup.

The Isky cam will definitely have a lope. I am running the next cam smaller - Isky Mega 264 - in a 350 and it has a slight lope at idle but comes on strong right off idle and pulls hard. If your 327 has cast pistons and not forged they are most likely .040 down in the hole and your compression is closer to 9:1 with your 461 heads. I would take a serious look at the MEga 264 for your application. If its running fine with the RV cam you will be very happy with the MEga 264.

The Isky Mega 264 will close the intake in about the same position as the cam you have now but has more overlap and more duration at .050. It will have a slight lope at idle and a better mid range and should rev better as well.

I had the Comp Cams 262 Xtreme in a 327 in my Impala and I really liked it. The thing is though that I changed the camel hump heads out for aluminum ones and increased the exhaust pipe diameter all at the same time, so I cant really comment on the difference between cams alone. It replaced an "RV" cam though and I liked it alot for a 327. You wouldn't go wrong with it IMHO.
