People with XE-262's...
My motor isn't running yet. And It's pretty beefed up compaired to the 195HP L-48. I've herd many things. But, most people have Hi-Perf. heads. I've just got ported 882's. What can I expect with this cam? How is the low-end torque? Will the motor wrap up to 5,500 while still making power???
Thanks,
Aaron

My cam is similar to yours, so: Yeah it'll work with a stock converter...My Comp Cams Book says that Cam is good from 1300-5600 RPM, so yeah you should make it to 5,500 RPM unless ya got another problem. Now, a Q from me.....shouldnt you have asked all this stuff before ya bought it? My $.02

Actualy, when I talked to CompCams I really hadn't done anything to my heads or exhaust. And I wasn't really planning on it. I just told them what my stock L-48 had and they recomended the XE-262. then I got headers, ported heads and so forth. I just wanted to see what the cam would operate like. My buddy with an XE-268 in his 74 4 speed pulls like crazy from about 2,000+ and REALLY starts pulling at 3-3500..

I put the XE-262H in my 383 when I built it. It idles just like my stock L-82 did. It really seems to work well with my 383. The guy from Comp Cams said that the XE-262H would produce better low end torque than a XE-268H but would have slightly less top end horse-power. Because I was concerned with losing too much vacuum, I opted for the XE-262H and have been very happy with it. Good luck.

Not running it. This should fix you up anyway. :cool: 383 is different so the cam appears smaller in 383, more lope in 350. Expect a nice cammed idle in your 350/auto. w/ 12-16 initial & all in by 1800-2800.

Re: People with XE-262's... (Ganey)
I have the same cam, use the Comp roller rockers @ 1.52 ratio. You don't have to worry about clearances as with the 1.6's and it makes it run and lope better.

I've already made sure the 1.6:1's will clear and they do. So, I think I'm going to keep them.
Ganey:Are you talking about 12-16 timing? That means that's at 2,000 rpm or something??
What's all of your idles set at??

1.6 rockers with the XE-262 here. Little bit more lope than the old Crane 272 Energizer but the Comp is ground on a 110 lobe centerline angle vice 112 (or it may be 114) for the Crane.
Dyno2000 says I gave up about 15 hp at 5000 rpm but gained about 20 ft-lbs in the 3-4000rpm range for this cam versus the XE-268.
Since my car is a daily driver, I went with the XE-262. It will pull to 5000 easily (probably 5500 with no problem but I only have about 750 miles on the engine so far). I like the fact that if I forget to downshift, the car is not killing itself when the revs drop to 1500 or so. :smash:
BTW: With my gears and the OD, I cruise at 70 ish at 2000 rpm so I didn;t want all top end.

Actually, I could careless about making 500HP@6,500RPM. I'd rather make 600FT-LBS @ 3500RPM. I love low-end torque. I like to be able to scare people and get to 60 REAL fast! :chevy

12-16 initial means at idle w/ vac. dist. adv. blocked. All in by 1800-2800 rpm w/ vac. dist. adv. blocked means total mech. advance.

Re: People with XE-262's... (Aaron-74)
Question whats the red line of the XE262 ? will it pull 6000 ? Crane has a magazine add on the 272 in comparison to the xe262 & they, Crane, contend 18 more hp & 15 fl lbs of tourque .............I will be doing a cam this winter on my 427 & looking for 6000 redline & 450 ft lnb of tourque the xe 268 seems to mild for a big block but i want tons of tourque .....i :crazy:
