Most of the aftermarket cams will mark them on the ends, so where the cam sensor is on the exhaust cam.

Those look stock to me though especially with the as cast finish between the lobes. Generally the aftermarket cams are turned there and have a nicer finish. At least the ones that I have had for my 420a.

Before I changed to my Crower Stage 2 Race Cam's Intake: 248 / Exhaust: 248, My Stock cams were Intake: 214 / Exhaust: 179 and were stamped like yours, the Aftermarket Crower's are stamped with MJ

Why does mine say 233?

 

[KYLE JORGENSEN]

that would be the size of the cam, you happen to have a bigger stock exhaust cam

when you buy aftermarket cams they will be 248 to 272 depending on camshaft maker (Kelford, BC, Crower, HKS)

It's odd that they wouldn't use the same cams in all the 420a Eclipses.

The crane 12 cams which are getting harder to find are 246 on both intake and exhaust. The crower 2 cams are 241, and Brian crowers stage 2 are 268. Crower cams keep a low duration but have the largest lift. The stock exhaust duration is 220 or something like that. I don’t see any info on anything with a 233

My Crower stage 2's are 248/248 and I love them perfect for street use, tuned right these give decent power for 420a Right now I have mine tuned for high top-end power (power is felt around 3500rpm and really felt at 5000rpm) gives that great boggy lope but I'm going to put more bottom power to even it out but it takes the hard bog away I like so much. but will gain better get-up

I got the crower stage 2s do I need adjustable cam gears to run fine on the stock ecu?

you can run the stage 2 with stock cam gears. I now have stage 4, Brian crower srt4 cams! with the stage4 adjustable cams gears are a must

That’s what I was hoping for since I just want a fun NA car didn’t wanna do ms or max effords just to get gapped by a stock k series
