I noticed xbgs351 also runs a CLS138 solid, anyone else? I'd be interested to hear from people using this cam as I dont see many running this cam. I've been running one for several years after changing from a F246, it was the best change I've made.

You got me interested - i was looking at running f246 as well, i havnt come to a set conclusion just yet but was about to start spending the $$ to get everything to match.

What is cls138 - manufacturer - and what sort of profile are we looking at.

Also what other components are you using, I assume single plane manifold, elec ignition, decent carb?, compression?, stally - 4000-4500?, diff gears? anything else?

What were the benefits over the f246?

Cheers

The specs read v similar to the F246's little brother the F238 dont they?

It is made by C.O.M.E Cams in Melbourne.
duration @ .050 237/248 , advertised 280/294. lobe lift .318/.335 multiply that by your rocker ratio,lobe seperation 112.
my car is a XC sedan, 4v c/c heads (untouched) torker, 800dp 10.18:1, dual point dizzy with MSD, FMX 2500 stall, 4.11's, 28x10.5x15 slicks Runs 11.92@112, 1.60 60ft.
it never had a good 60ft with the F246 as I only run a lowish stall speed and really needed to be reved hard (compared to the CLS138) I change at 6000 max, shift light is set on 5,800 but the recall usually says 6,000. In short it is very streetable, dosent need a big converter, and runs harder.

It's one of their bracket master solids (lift: .541 / .570). Similar to Crane F238.

Their new website doesn't seem to list all their parts yet.

Their CLVS648 is their closest off shelf cam to an F246.....has just a tad more duration and less lift.

Adv Durn: 293 / 302
0.050 Durn: 249 / 258
Lift: .546 / .588
Lobe Sep: 108*

I used that cam in a basic clevo,only 9.7 comp,open heads ported,single plane ,750dp,msd ,3500 stall and 3.7's in an xy ,was a tough setup,great on the street,fairly cammy but nice manners and went hard,made power on the dyno to 6600rpm.

I think the crane F238 is a far better street/bracket racer cam than the F246 as it has more low down torque. Wished I had one of those in the 351 instead of the F246 copy but overall it wasn't that bad.

MY 351 WITH 302 CONRODS F238 CAM, HOLLEY MANIFOLD, BG 750, HI-6, PACEMAKER EXT, AND GOOD 2V 270cfm@28" HEADS GOT 332HP AT REAR WHEELS AND MAXED AT 6300RPM. TOP CAM FOR STREET AND STRIP AND GOOD MANNERS WITH A 3500 STALL AND 3.7 GEARS.
ITS GOOD TO FIND A CAM AS GOOD AS THIS....

PS, THE HEAD PORTER RECOMENDED THIS CAM BUT SAID IT WOULD FALL FLAT ON ITS FACE AT 6500RPM.

One thing that I have noticed with the CLS 138 is that my exhaust is extremely quiet. The exhaust on my car was far from quiet in its previous car. Have others running the CLS 138 also found there car to be very quiet?
