Has anyone used one? I found a few reviews on other non ford sites and they seem to have a good rep, I am considering dropping one of their cams into my truck when money permits it. I was looking at possibly going with the 280936-10 being as its pretty close to the comp 260 and I have driven a 6 with a comp 260 in it but am wondering how this particular cam would compare to the comp 260.

 

I've used quite a few of them and never had an issue.

 

"... its pretty close to the comp 260..." That is how it compares to the Comp 260.

 

I'm thinking so, my trucks geared way low so I was thinking it may provide a little more uptop without getting to crazy.

 

I think you should take a look at the Accelerated Motion cam #21378. Improvement at the mid-range where you'll be operating with the 300, and still give great towing. It will also give you a mild loping exh. sound.

With your high gears, you should also look at the Crower Cams # 19213. That cam is mis labelled as a 'level 4 performance' cam. Every mechanic I speak to says their write up is a crock. They put the wrong write up on that cam. It has 210/213 duration @ .050", and .456/.461 valve lift, with 112 LSA. (Really? a 'hot street/drag cam with 112 LSA? That cam may not even lope at idle!!) Anyway, after my rant, it does sound like an interesting cam.

 

I like the split lobe design on that crower cam, and it doesn't matter what they label it numbers speak for themselves it having a split lobe is nice imho and seems to offer a really nice increase on the exhaust.
That one is definitely not a stage 4, I don't see how a 210/213 duration at 050 would bring you anywhere near a 6500 redline, its got less duration at 050 then the comp 268 and only a little more lift on the exhaust valves. I don't think that comp 268 six on youtube was pulling rpms near 6000 let alone 6500. Crowlers 19205 grind may but not that 19213.

As far as sound goes I don't need a lope, I am more interested in getting more bang for my buck without turning it into a gasser, my truck is straight piped it sounds fine like it is lol.

My thoughts behind the howards 267 were that because there is only a small increase in duration 213 at 050 over the comp 260s 212 at 050 the powerband would be similar however due to the increased amount of lift at .480 on the valves compared to the comp 260s .447 it would make for more power. I'm just thinking that .480 lift on the valves may be overkill in regards to fuel consumption.

 

While researching cams I found something very interesting: On the Acc.Motion site he mentioned that max. efficiency lift on your int.valves is usually 25% of the diameter of the v.face.

With my Isky 256 I have .450 v.lift. However, I did run 1.7 roller rockers on it for a while. That gave me .483 valve lift. I did see an improvement in performance and gas consumption, but I thought that due to the 'ridges' I have in my c.chambers.

I agree with you about that Crower cam, but the techies at Crower won't listen to me. People can't think for themselves. I do prefer the Acc.Motion cam though, b/c the p.band comes on earlier in the rpm range, 212/213 duration @.050, .450/.451 v.lift, with a 109 LSA. It is really close to the comp 260 and the crower 19213, but with 1 less degree LSA than the 260, and 3 less than the crower. It is the Isky 262 with 4 degrees more duration. Good luck.

 

Crowlers descriptions are terrible, they list their stage 3 as having upper bottom end and good top end? I'm thinking they meant mid range unless theres a nice flat spot inbetween lol. I dunno I'll keep looking into it, I need to finish moving and install the power upgrades to my steering and brakes so I have time. Only problem I see with that first company is they're in Canada.

 

I doubt you'd feel much difference between any of those cams. Since you're not in a rush just call all of them and see who inspires the most confidence. Schneider and Isky cams are worth looking at as well.

Are you running the stock intake/exhaust? There's not a whole lot more to be had up top without head work regardless of the cam. Mated to the stock intake/exhaust it's not letting you get much above 4,000 rpm even if you put a 290 cam in it.

 

Nah offenhauser DP with a 500 afb and efi manifolds going into 2.5 pipe dumped at the rear axle. I don't plan on taking off the head until money permits it being as my truck needs ALOT of other things and my compression is good on all cylinders plus I have a 240 head off of an older truck thats in decent shape that I plan on building up at some point down the road. My engine will hit 4000k if I am in fourth with my foot into it, I've only pushed it that hard ounce though being as its awefully hard on it and at those speeds I need a lane and a half to keep it straight.

 

Cool. I'd go a little smaller on the cam than you think you want. Better to give up a little at 4,000 where you never take it for now, then once you slap on a worked head you should gain 1,000+rpm on the top end.

 

Ya I just got home and filled my tank up right after getting off of work.. My foot is growing lighter and I am thinking a OD is coming before doing anymore performance mods to the engine I get decent mileage if I cruise 40 and pop neutral followed by a 25mph coast when I see a redlight lol but my shift gets changed in a month so I won't have the roads all to myself and i'll have traffic to contend with so my mpg is gonna drop.
