[TransAm 474]

Good evening everyone, I know there is a bunch of people here who are using the Summit 2802 camshafts. Does anyone happen to know or remember what the number stampings were in the end of the camshaft? I'm just trying to verify that I have the correct camshaft. I have contacted Summit, but haven't has a reply as of yet.

Thank You

I've got a 2802 sitting on the shelf. It has "E1221R" (stamped numbers/letters) and "Z014" (made up of multiple "dots")

Thanks, I really appreciate it. Ours has "Z14" (made up of multiple dots) and it has "1794" (stamped numbers). During my research, I found that Summit also offers a "1794" camshaft, which is a small Single Pattern 272/272 Adv 216/216@.050 .454"/.454" lift for Pontiac. I just wanted to be sure it wasn't put in a "2802" box by mistake, but after measuring the lobe lift on an exhaust lobe, it is showing .325" which is exactly what a "2802" should be. A .325" lobe lift x 1.5 rocker= .488" lift. So I have came to the conclusion that the "1794" stamping must be just a coincidence. I appreciate the help

Doing a bit more research, are you sure your doesn't say "E1221P"? That would indicate that it is an Elgin Camshaft, they have the exact spec as the Summit 2802, still kinda buffalo'd why mine is stamped "1794"

Here's all the numbers/letters I could find on my 2802.

Thanks Ponyakr, what is the number that is stamped where the White dot is on yours, its hard for me to make out in the picture, but I can see there is a stamping there. I can see the "Z014" thats made up of multiple dots very good

That "Z" looks more like a "2" to me, because the top right hand corner is round.

Those are the only numbers/letters I could make out, even using a magnifying glass.

"... the manufacturer, which...I believe to be Elgin Camshafts...."

I suppose that's possible. I figure Summit has changed cam suppliers, just as they have changed HFT lifter suppliers, thru the years.

Paul Spots has stated that he thinks most all the common Pontiac cams are made by the same cam company & sold under lots of different brand names. Sometimes the specs are listed just very slightly different. Probably exactly the same cams. I think the cams listed as the Summit 2801, & 2802 are exactly the same cams listed as Speed Pro cams CS1022R & CS1175R.

Paul Spotts sells a cam he calls an 067 high lift. Looks the same as a Summit 2800. Says it's made by the same company that supplies Melling & others with cams. Don't know who that is. He also sells what he calls an 068 high lift, which looks like the Summit 2801. & I think he did list a 744 HL which looked like a Summit 2802.

https://www.ebay.com/itm/Pontiac-V8-...oAAOSw2s1Uwp5F

The cam in the Edelbrock 5057 kit looks like the Summit 2802. Edelbrock don't make their own cams. Don't know who does.

https://www.summitracing.com/parts/edl-5057/all

Also lots of brands for the popular 068 & 041 clone cams. Don't know how many brands actually grind their own. Guessing that MOST, buy from one main supplier.

I just now talked with a tech at Summit Racing about this, and we have came to the conclusion that what I have is indeed the 2802 camshaft, that has been possibly stamped incorrectly at the manufacturer, which in this case I believe to be Elgin Camshafts. He said he wasn't allowed to tell me the manufacturer, but he said Elgin is a big possibility. The reason I believe it to be an Elgin grind, is because their "E1221P" grind is exactly the same spec as the 2802, and when I ask the Summit tech what the stampings are suppose to be on the 2802, his reply was "our 2802 should be stamped with E1221P". Now, both Elgin and Summit show a "1794" camshaft for Pontiac as well, it is a small Single Pattern on a 110° LSA. The Summit is the exact Spec of the Elgin with this cam as well. I measured an exhaust lobe on our camshaft with my caliper, and it comes out at 0.325" just as it should according to the 2802 cam card. So I think what has happened here, is the camshaft is the correct 2802, but was mistakenly stamped as the smaller 1794 single Pattern cam at Elgin.

Just to be sure, I'd be measuring the intake lobe also and if possible, put it in an engine and degree it to see what the lobe separation angle is.

[TransAm 474]

Thanks, I've talked with Summit again today, and the guy I talked with this time also informed me that the 2802 should be stamped with E1221P. Mine is stamped Z141794. I have now measured the Intake and Exhaust lobes. The Intake lobe comes out at 0.311" and the exhaust lobe measures 0.325". Both are exactly what the 2802 is suppose to measure. So I have came to the conclusion that it is the correct 2802 camshaft that has possibly been mistakenly stamped as the smaller single pattern 1794 camshaft at the manufacture. Measuring the lobe lift tells me that is is not the smaller single pattern. Its either that, or the camshaft is from a different supplier, and it is just a coincidence that it has the 1794 included in the stamping. In the end, it doesnt matter to us, as long as we have a 2802 camshaft Lol

Don't know what your putting it in, but I gotta tell my 2cents worth. I have 1 in my rebel now, I replaced a voo doo 702 that lost a lobe. I was afraid the metal in the engine would ruin another cam so I went cheap with the summit kit.
At the track, the 702 was just a tad quicker. But seat of pants, and tire shredding ability, and sound was much better with the 702. It also cost bout 3 times as much.

Thanks, the 2802 is going in a 1970 9.8-1 compression RA III 400, stock #12 Heads 70cc chamber, Ferrea stainless valves, Crower 68404 springs, Icon 14cc dish pistons, Eagle H-Beam rods, factory crank, Felpro 1016 gaskets and zero decked, stock '70 intake, 7040270 Qjet setup with Cliff Ruggles kit and parts, factory points distributor recurved by Cliff Ruggles. It is going in a numbers matching 1970 Trans Am with a TH-400, Hughes GM25-BOP converter, and either 3.55 or 3.73 gears.

I am interested in hearing the specs of the engine that you ran the 2802 in if you dont mind? Thanks

It's a 60k mile, out of a 73 Bonnie 455. Rings, bearings, 400 heads,stock intake,exhaust manifolds. Only mods, I built a cliff book q-jet, and had the lunati 702 cam, with recommended springs. 2.5 dual exhaust. The 702 is a great cam for a stockish build. Idled bout 600rpm with a stock converter. Pulls hard off idle to bout 4800-5K.

"...The 702 is a great cam for a stockish build...."


Just curious as to the current price of one of these Voodoo cams. So, I Googled it.

Best price i found was about $146 shipped, from an Amazon & Ebay seller. No tax. If Amazon ships stuff, they now charge me tax, as does Summit. Can still find Ebay & Amazon sellers who don't charge tax. As the cost of parts gets up to $100 & more, the tax makes a difference, for low budget guys. So, I always consider this, when pricing parts. The day may come when ALL online sales will require tax charges. I'm sure all the "brick & mortar" stores wish it was law NOW.

https://www.amazon.com/Lunati-105107.../dp/B01A863XG8

https://www.ebay.com/itm/Voodoo-219-....c100005.m1851

Summit price for this cam is about $163 + tax, unless you can talk the salesman into a price match or reduction of some sort.

https://www.summitracing.com/parts/lun-10510702/

Jegs price is $150 + tax. I'm sure Summit will match or beat that.

https://www.jegs.com/i/Lunati/638/10510702/10002/-1

Some sites won't reveal either the shipping or tax charges 'til AFTER you give them all your other info, and JUST before you click the final BUY button. I very seldom ever buy from those sellers. Many sellers have an option to "estimate" the total price. This provides a quick way to compare total shipped prices. May not concern some, but is important to low buck buyers.

. The day may come when ALL online sales will require tax charges.

That day is here. They passed legislation about 2 months ago that all internet sales will have taxes. It's just taking a while for all places to get on board. Summit and Jegs are both charging tax now, as well as some ebay and a few of the vendors I deal with. Some however haven't changed yet but I suspect they will the first of the year.

Anyone have dyno data 2802 / 400cuin. With Good compression ?
I ran a crane cam very very close to 2802 specs in a 1968 GTO automatic with headers it needed a gear and converter for optimum results but it was sure fun in its power band

THIS^^ ... I would also like to see Dyno results of a High Compression 400 using the 2802 Camshaft. I know there are a lot of people using the 2802 in their 400, but you don't really hear as many stories about the results. I've read some say the 400 with a 2802 Camshaft has tire roasting low end, where others say their 400 was soggy on the bottom end with no tire burning power. Maybe the ones that lack the bottom end power weren't tuned properly(Carb and timing), geared properly, not enough converter, or too low compression? I sure hope the 9.8-1 RA III 400 that we are building has good tire burning low end, but ours will have either 3.55 or 3.73 gears and a Hughes GM25 converter. I would like to hear more stories about people's results using the 2802 in their high compression(9.8 and up)400's.

There are always Rhoads lifters, to add some low end. But, that makes the Summit cam, less of a bargain price.

Since the Rhoads lifter price increase, a decent cam with more bottom end, plus regular lifters, can actually be cheaper than a Summit cam, with Rhoads lifters.

There are options.

.

Install position is a big player. Many here just stab camshafts in place without checking anything, and no idea where the ICL ended up. Could be anywhere with stacked tolerances playing against you.

It's only a 224 @ .050 camshaft and the LSA is spread way out at 114 degrees. It's not going to be an outrageously rambunctious idle and should still produce decent vacuum if the compression ratio is decent. I'd put the ICL at least around 108 degrees, and with a proper carb and distributor tune it should work nicely in a 400, and the Hughes converter you chose and the rear gear, should run pretty good.

Years back I ran a 2802 in a 428 with stock converter. It idled smooth and performed decently for what it was.

I think the 2802 is too big for a 400 that's going on the street. The 2801 would be much better... Im talking street, since this is the street section and not track... Soggy, lumpy, drag racing cams on the street are an exercise in misery when you could be having so much fun with a smooth running, torquey motor with power brakes that work..
