Did I get screwed?

Trav4011 · Jan 24, 2007

I purchased a set of cams from a local guy.. I know the guy, and trust him, so I didn't really take a look at the cams except to give them a quick once over to check for dings/scratches.. They are in Comp boxes.. and he said that they have the following specs..

.531" lift
292* duration
114 lobe sep.

I was looking at them earlier.. and noticed a part number stamped on one of them. It looked like a Ford part number.. so, I punched it in on google.. and sure, enough, the part number for a PI cam came up.. The part number is:

1L2E 6A274 CA

Are these cams ground on stock blanks...? Or, did I get screwed with a set of stock PI cams?

it sounds to me like he put the wrong cams in the box, or he tried to screw you. Im no expert though.

The 1L2E 6A274 CA is the lefthand Romeo PI cam. The righthand cam would be identified with 1L2E-6250-DA. If both the cams have the 1L2E 6A274 CA markings then not only did he give you stock PI cams, but he gave you 2 left cams.

Dude screwed you. There is a very distinguishable difference between a .531"/292 advertised duration lobe and a stock PI lobe.

Tell him he'll find one embedded in his windshield and the other rammed up his ass if he doesn't give you your money back.....and fast!!!

Comps would have XE*** as their part number etched into the cam unless they are custom grinds. Still...Comp doesn't even list a 292 duration cam in their catalog for a Ford Modular motor.

After some searching.. I believe that these are Houston Performance regrinds..

Looks like the lobes have been welded on, or heat treated..

double post..

I just received my billet s292 houston performance cams. The 292 duration is the advertised duration not the actual.

Regrinds use the old cam shafts that's why it has ford part numbers. You will need new cam gears and bolts. 99-00 windsor heads have pressed on cam gears, the 96-98, 01-04 romeo heads have bolt on cam gears.

MBDiagMan · Jan 25, 2007

I know that several years ago, the only cams available were regrings due to the manufacturing process for these cams being difficult for small companies to reproduce. For that reason, the early cams available would have been originally made by Ford and then reground by Comp or whoever. To know if you were jipped on this, do some research to see if there was ever a time when Comp Cams was regrinding Mod cams rather than producing new ones.

BTW, the manufacturing process consists of the shaft being a hollow tube over which the lobes are pushed into place like a skewer. The lobes are then indexed properly and then a steel ball is forced through the tube expanding the tube against the lobes to hold them in place. This was a difficult manufacturing process for small cam companies to reproduce. I expect that the cam companies are getting blanks from some manufacturer, maybe even Ford, rather than duplicating such an expensive process.

Can you do me a huge favor.. and take some up close pics of them.. Also, what do you measure from the flank (bottom most part of the lobe), to the tip on the intake and exhaust lobes. I get 2.126" and 2.095".

Ok.. I just checked with Houston Performance.. They confirmed that the cams are thier S292 setup.

I guess that would all depend on if he was expecting a set of Comp cams, or just cams with those advertised specs.

Gearbanger 101 · Jan 25, 2007

I'd still shove one of them through his windshield for good measure.

or take your old ones out, put them in the boxes and say they werent the right ones.

Honestly.. he didn't know much about the.. He gave me those specs, and told me that they came in a Comp Cams box.. which they did.. I purchased them for 225.00. He had purchased them from a guy that had them installed in his 680whp Saleen. Tim at MPH talked him into the MPH blower cams, and they were swapped out on the dyno.. These cams have about 500 miles on them.. and my buddy bought them to go into his Lightning. He never got around to it, and they've been sitting in his storage room for almost a year. So, I picked them up cheap.. I didn't care much about the brand.. The specs are good for a blower setup, but, I just thought that he had given me stock cams.. which is why I was p*ssed.

I'm not that kind of person.. I just wanted to make sure that I didn't get ripped off.

jivepepper · Jan 25, 2007

They average between 50-60 whp on most blower applications.

From that picture those are clearly not factory lobes. I can tell by the nose radius and lift alone. Those don't appear to be welded lobes but rather a PM(powdered metal) lobe that has been diffusion bonded to the core by means of heat. Some of the factory Ford camshafts are done this way and some are manufactured with the process that MBDiagMan descibed. But these are processes only used by Ford, not aftermarket cam manufacturers.

All the modular camshafts that are produced by aftermarket companies such as Comp, Crane, and Crower machine and grind our cams from one big chunk of round bar stock...billet. These companies also make cast camshafts that are finish ground, but all of the aftermarket modular cams by these companies are billet. And I know at least Comp, Crower, and Crane do not re-grind factory camshafts and have never done so. The modular camshafts from them have always been billet.

If I were you, I would go spend $30-$50 bucks and take your cams to somebody local that has a Cam Doctor or Cam Pro. They will run both cams through the machine and give you a very accuarate cam specification card. This way when you degree the camshafts you will know the cam specs.

BTW the flank is the uppermost part of the ramps closest to the top of the nose radius (peak lift). The heel is the bottom of the base circle. To measure lift, first measure with a caliper the width of the base circle, and then measure from the center of the heel to the peak of the nose radius and subtract the difference.

Almost everyone was using those HP 292 regrind cams a few years as they were the only thing around. How much did you pay? I usually see them go for @ $250-300 used.

Did I get screwed?
