Has anyone used the Summit 2801 cam? It was described as a replacement for the 068. Also anyone know who the manufacturer of the 2801 is? Performance gain?

[stockapearing455]

Probably a good street cam for 400 and a small cam for a 455. My friend had one in a stock 400 and it ran 14s in a stock 1971 firebird.

Comparing the 068 and the 2801, the 2801 has a taller lift 443/465 vs the 068 at 408/406. Almost all of the other specs are real close. (duration).

[Red GTO 66]

It look like summit changed K2801 spec. Now it looks more like Melling 26204 or Crower 60918

Old 2801 272/282 214/224 .442/.465
SUM 2801 288/298 214/224 .444/0.466
MEL 26204 288/298 214/224 .443/0.465

Something often overlooked is the lobe seperation. The 068 cam is on 116° lobe separation angle while the Summit is on 112° lobe seperation angle. If installed as recommended this puts the 068 cam intake close point at 39° compared to the Summit which is at 34°. The 068 should tolerate more compression because of the later intake closing.

[Tim Corcoran]

The 068 was designed for more compression and higher octane fuel that we no longer have. Even if the 068 had more lift it would not be a good choice for a 9.5:1 street car that runs 92-93 octane pump gas. Yes the 068 would tolerate more compression but would need higher octane fuel too.

I wonder if they softened the ramps for lack of zinc in today's oil?

[War eagle]

The Sealed Power CS1022R (112degree LS) is also showing the same specs. The .214/224 lift is appealing as there should be plenty of vacuum at idle. I will be keeping my 3.23 and wide ratio muncie. ( Had hopes of finding a set of used 3.36's) A clean-up bore of .030 on the 389, and stock 716 heads, this should make a comfortable street car and a 'fun once in awhile punch' to clean out the trips. I think I will try the 2801.

[Skip Fix]

I have the old one in a low compression 400 slight lumo at idle and runs good , like a stocker.

[2002Z4CSS]

I have a low compression 1975 400 in my 1971 GT-37. It has a Melling cam with the same grind as the Summit 2801 cam. For an old low compression 400, this car will break the tires loose at a 30 mph roll on dry cement every time you nail the throttle. Sounds pretty good too. I have some 245/60/15 Goodyear Eagles on the back and they just love to burn off.
Here is what it sounded like just after we installed the new Melling cam/lifters. No tail pipes and some smalll 2" exhaust pipes with turbo mufflers from a 1968 Lemans we once owned. Just to make it quiet after rebuilding the engine so we can hear any noises it may have had. Click on the pictures for the video.



This is what it sounds like with the Pypes 2 1/2" Street Pro all stainless steel system with Pypes "X" pipe and splitter exhaust tips.



There is a video on the Pypes Exhaust site of my car.

Great looking 71. I know my biggest problem will be convincing myself to alter the stock ex. manifolds. I am well aware that a set of RA manifolds are a bolt on but I was building as close to stock externally this particular 64 GTO. That cam needs some free flow by the looks of the lift. But I am not going to be racing so probably will just put her back original. In fact its balanced but I have not even replaced the press in studs. I may look RA manifolds down the road.

Speaking only for myself here, but the choice of exhaust manifolds (stock, HO or headers) would alter my choice of cam selection. Mainly in the lobe seperation. Tighter for the headers and wider for stock cast manifolds.

Here is some good information posted by b-man on getting the stock logs to perform as well as the RA manifolds. http://forums.maxperformanceinc.com/...haust+manifold

I bet they just changed the way they measure the same cam. that is the problem with advertised duration

[Jim Doran]

I have the 2801 in my 389 / tripower / 3.55 / 4spd / 77 heads with 1.65 Rockers. Pretty sure you are going to need adjustable rocker nuts with the 2801.

Performance everywhere is great ,plenty of vacuum, and zero complaints.

[lust4speed]

Edelbrock also has the same cam, but for twice the price. I'd bet they came off the same machine.

[A.J.]

Sorry for jumping in here but, would the 2801 be a good choise for my GTO, 389 4 barell, auto and 3:08 in the rear?

[Jim Doran]

AJ, I think the Summit 2800 is a much better fit for your combo.

[moontower69]

For a 389 with 3.08s and an auto, I'd try the Crower 60240 (210/221 @.050) - pretty much in between the summit 2800 and 2801. With more gear, the Summit 2801 or Crower 60241 will have great performance with a 389/400 in the 8 to 8.6:1 compression range.

I've got the Melling version of the 2801 cam in my 455. I wanted it to idle and cruise like a stocker instead of a performance car, so did NOT want to over-cam it. The CR is somewhere around 9.5:1 but no hint of detonation (except once when I got some bad gas) so the ramps must be pretty forgiving seat-to-seat. The engine has silly-strong torque on the bottom but still pulls nicely through 5000 RPM. First and only time I took the car to the track a few months ago it ran a 13.6 without any prep and with a 3.07 posi and 3-year old Firestone Indys out back.

By no means a "racy" cam, at least on a 455, but works quite well for a street cruiser.
