Are these Evo cams?

[74runner]

I've been searching around but can't seem to find info on these cams.

I'm told they are 264's from an Evo 3 (1995) Here are the #'s on them 210170921 and 210170223 the #'s are on the ends opposite the cam gears.

I found a useful link from Crane cams showing stock cam shaft part #'s and spec's from 1989-1999 but, I can't post it to the Cam Threads already started because I'm still new

Assuming they are Evo 3 cams how do they compaire to my stock cams in my 1991 Eagle Talon awd turbo?

Build:
16g
FMIC
190 Pump
550cc injectors
AEM cam gears
GM maf
3" exhaust
Mild ported head,intake, gasket matched TB.

Found a link for Evo 3 (1995) My cam's are not in the list:

The Exhaust cam on the Evo III is identical to 1g 90-94 dsm turbo M/T.. The intake cam has a different part umber than the 1g dsm, i had a page on that..one sec

Edit: Found it. Apparently after 1995 the EvoIII Intake cam part MD335754 number superceeded the old number.

Thanks! That could be why I can't find these numbers any where but still doesn't confirm them being Evo3 cams unless you know for sure that my numbers are the old ones?

Are you able to measure the evo III cams, to see if they are identical. Check out this link http://www.dsmtuners.com/forums/articles-engine-fuel/450028-how-figure-camshafts-lift.html
Compare to this data measurements i found for 1g cams n/t and turbo
90-92
intake 1.3974 lobe height
exhaust 1.3777

Intake cams
NT & Turbo w/manual trans 1.3974 lobe height
Turbo w/ auto trans 1.3858

Exhaust cams
NT & turbo with auto trans 1.3858 lobe height
Turbo with manual trans 1.3974
I hope this helps out

I was thinking about that, I'll have to pick up a new Battery for my mic tomorrow and then post my findings...I have 3-4 sets of cams from 90-92 Turbo awd manuals, so I'll check them all. Thank's!

I just double checked with my bud, he pulled the cams from an Evo 3 for sure, but who knows if they had ever been swaped out over the years.

Exhaust cam.
Base circle on: 1.178
Toe measurment: 1.370
0.192



Intake Cam.
Base circle: 1.179
Exhaust cam: 1.372
0.193



1.7 x 0.192 =0.326 intake.
1.7 x 0.193 = 0.328 exhaust.

Unless I did this wrong they are just worn out stock cams.

Does any one have any thing to add? Still looking for answers and info.

Are you sure the mic measurements were correct? Thats crazy if they have that much wear.
I found this as well, if you have these markings on cams.

intake: ID mark B,C,E,F:1.3858-1.3661

exhaust ID mark A:1.3858-1.3661
exhaust ID mark C:1.3972-1.3776
exhaust ID mark E,F:1.3744-1.3547

EDIT:Measurements from nose to base circle with service limit
Intake

Thank's for the info!
I'm going to re-check the measurements in a few minutes and get back to you.

Here it is in detail:

Intake Base circle 1.181" or 30.06mm

Exhaust Base circle 1.180" or 29.97mm


Intake Toe 1.377" or 34.90mm

Exhaust Toe 1.181" or 34.87mm

Intake cam:

Toe 1.377 - Base 1.181 = .196 Rocker Ratio 1.7 x .196 = 0.3332
Convert inches to mm 25.4 x 0.3332" = 8.46328mm
