Mis-match right there with a 2200 stall converter and the HSD intake.

And I think we can agree for the most part with the issues here the Comp 280H is a "041" cam. 230 at .050 give or take, exclude the lobe separation issue, etc.

And as stated your stuck with it.

[P@blo]

Ah man!, I don't want the ram air 41 in my portly automatic. So now i will have to get like 4.11's and a 3500 stall, I was hoping the 280H would be have less top end but more torque that the 41 and figured i might alright with the magnum.

[speedshopmike]

DONT INSTALL NEW LIFTERS ON A USED CAM!!!!!!!!!!!!!!
OR VICE VERSA!
DUMB, STUPID, DUMB, BAD, NO, BAD, DUMB, DONT.

ok, i feel better now.
otherwise, rhoads lifters kick ass.

if you want more bottom end power, advance the cam 4 degrees.

[speedshopmike]

a comp 280 is no 041 cam any more then any other not-the-same cam.
duration at 050 is but one small aspect of cam design, and not really the most important.
a 280 comp in a 400 inch motor will want a 2600 stall roughly and will pull a 2200 just fine.
it'll idle in gear, about 14 inches at 900 or so rpm off the top of my head.
i'd go dual plane, or think about splittin the plenum with a divider plate to boost the signal at lower rpm.

Did I say portly, I meant to say sportly automatic.....lol

Hey Pablo, I used to run the 280 mag. cam in my 400 with an old Torker single plane intake. I switched to the Edelbrock RPM duel plan and man what a difference in torque on the low end.

I'm currently running the Comp Cam 274 XE cam. This is not because I didn't like the 280 mag. Motor needed a rebuild and just want to try something new. Stick with the 280 and get you a duel plane intake. James

[Steve C.]

Ok, I agree that the various "230 degree" cams, give or take a degree or two, are not the same and should not be lumped together, and yes they have differences... but with that said I'll bet you wouldn't see much difference between them regarding track performance in the situation here at hand.

Comp Magnum 280H, Comp XE274H, Crower 60919, Ultradyne 288/296, Crane 9794041, Isky 901281, etc, etc..... to me all just "041" type cams for conversation. And again you could probably build a test mule engine and try each one in a car and chase down .1 or .2 seconds and 1 or 2 mph with the difference.

But then that's just a total guess by me. I have not spent 20 years chasing numbers on the same basic combination with the same basic cams.

I remember reading that Crane has a lifter that works like a Rhodes, without the ticking noise at idle-

[rolling money pits]

outside of rhoades, what other lifters out there have the better snap ring retainer, as opposed to a cheapo circlip? street engine, not a full race / limited use.

i looked at both comp and crane, and niether seemed to identify the type of retainer used.

[Region Warrior]

I have tried crane's and crower's version of the 744 about 10yrs ago.
Now i have a crower 041 cam in place of crane's 041.
All are just alittle different profile. Performance wise in my car, not any noticable difference.

[P@blo]

I agree with Steve on that cams with similar durations at .050 will all be close in performance. Like if you were to take a engine with a XE 274 and swap only the cam to a 280H or a 041 I'm betting they would all be within a couple of tenths of each other. Splitting a few less ass hairs is on my to do list, or maybe a new years resolution. lol

[form406]

pablo im pushing a whopping 7" of vacuum @ 900rpm...jumps to 14 @1500 rpm's...im using summit lifters...ill be putting the right cam in eventually...but aside from muscling the brakes at low rpm she aint no dog and sounds like a funny car... hitting the track next year...

The noise drove me nuts, and so did the 1,000,000,000,000 times I had to answer the question, "What's that ticking noise?".

They work as advertised, and are a very well built lifter, AND THEY ARE NOISY!

If you are looking for something extra from them, you will get:

1. More vacuum
2. Smoother low end power
3. Tick, tick tick!

I must agree. My new solid cam is WAY quieter than the rhoads. I'd stay away from them.

My Crane hydraulic roller lifters have the good rectangular-section rings. They darn well better, at $430 from Summit! Haven't looked at many hydraulic lifters in recent years. Forty-five years ago, all hydraulics had round-wire retainers. But they weren't a problem unless some other part failed- like a bent pushrod, allowing the lifter plunger to hit the retaining ring. Even then, I personally never had one come apart- just beat up the ring and its groove.

Dan what solid did u go with?specs?
