Best 383 Cam for Torque ?

I have a 383 in a 73 camaro. 2000 stall/th350/3.08 gear. I need to change out my cam & lifters because of a lobe gone bad. What is my best choice for torque, not high end HP? (it will never go above 5000rpm.) Thanks

Re: Best 383 Cam for Torque ?

CompCams CamQuest6 software recommends the XE262H with a 1300-5600 rpm range
Hydraulic-Excellent response, good mid-range, noticeable idle

If Hydraulic Roller, the software recommends the XR270HR

The 260H is '18th place' on CamQuest6 for recommendation. Torque curve similiar, but 18 less HP at 4000 rpms.

I used '4 - Auto - Excellent in Daily Driver - Slight-Mild to Choppy Idle' for the Usage selection.

Re: Best 383 Cam for Torque ?

I've been running a comp 270H in mine. "Torque" is an understatement.

Chassis dyno pull started at 2000 rpm, well over 350 ft-lbs there, peaked at 400, peak HP was 293 @ 5200. cam is coming out, pm me for a "special"

Might be a good deal for him as he already had a burnt lobe on the last one. Maybe this was the noise on #6 cly. If all lifter are in the same place, breakin time is done.

Lou, was this the problem?

Re: Best 383 Cam for Torque ?

For a solid lifter, I ran a Comp Xs290 and ran in the 11s. Globs of torque. Hit 501 TQ rear wheel on the dyno.

Re: Best 383 Cam for Torque ?

I ran the CompCam 280H for years in my 406 and torque was never a problem, traction was

You should state your full combo for the best reply.
It seems the flat tappet XE cam line has the most issues with lobe failures

Re: Best 383 Cam for Torque ?

I used a sealed power CS-179R in my 383 (350 hp 327 grind)
and it was surely a stump puller.
everyone was always wondering what cam I used because their 383s never had the grunt mine had.
got mine here:

What about the GM hot cam? Hydraulic roller so no "burnt lobes".

Re: Best 383 Cam for Torque ?

The 280H and XS290 duration cams are too high for a 3.08 gears rear end
Lets not turn this into another XE bashing thread, we have enough of those BS threads with 95&#37; of the posts coming from people who have never owned an XE cam

Re: Best 383 Cam for Torque ?

I only stated what I gathered from posts on wiped lobes and what the majority were (or seemed to be).

I ran the 280H with 2.73's and a 2200 converter which had no traction on the street below 40mph on regular radials when nailed ... yes not an optimum combo but would 2.0 60' all day with a best of 13.5 @ 101 using only 1st and 2nd with a th350 tranny.

The "ricers" never expected 1st gear to go to 80mph @ 6000rpm, grab 2nd and burry the speedo. You know the "muscle cars" aren't any good on the hiway lol

Re: Best 383 Cam for Torque ?

was wondering about the 327/350Hp.(222/222 duration @.050) I've used it in a few 350s & liked it. The XE was too much for the 3.08s.(well actually if I had a higher stall converter it wouldn't have been that bad).(Very noticable Idle). It WAS the problem for #6 !. I'll look some more at the Comp Cams.
