I have a Sig Erson cam part no E410421,The box says grind:Hi. Flow:1H,There are markings on the cam I believe 186/180? I need to know if this cam can be used for a street application. I don't know how old it is,but it is new in the box,never used.

If any of you know about this cam I would appreciate any input you can give me. I am in the process of putting a 440 into my '70 Challenger. This cam has been floating around for awhile and I would like to use it if at all possible.

Just looking at it I can tell it doesn't have much duration, lobes are quite pointy.

Thanks,anything will be appreciated. I'm a newbie here,and I would like to say you have a great site here

When you build an engine, the cam is a major key to satisfaction. If you can't find out exactly what the cam is all about, try sending it to a cam grinder for evaluation. It may be an RV cam. In which case you don't want it unless you're building a boat anchor.

Straight from an Erson Catalog: Excellent choice for slightly modifed street machines or muscle trucks seeking improved low-end torque and mid-range horsepower. 383-440 engines run best with 8.75-9.5:1 compression, aftermarket dual plane intake, 650-750cfm carb and headers with large diameter free flowing exhaust.


BASIC RPM RANGE: 1800-4800rpm


E410321, Hi Flow AH


Advertised Duration: 284* intake, 284* exhaust


Duration @ .050 220*intake, 220* exhaust


Gross Lift, .472" intake, .472" exhaust


Lobe center  112*


Advance 4*


Sounds like a good street cam with those numbers.  If it were me I'de use some 1.6 rockers and a medium stall convertor.  Just don't forget to check valve to piston clearance with the 1.6's.


Have Fun

I also have a sig erson cam that I don't know much about. I got it from a local racer. all he can tell me about it is it has a 589 lift with a 320 duration.it is a solid roller for a big block The number's stamped on it are R-990-C. I need to find out the rest of the specs. centerline,overlap,valvelash,and timing.also what gears and converter. If anyone can hep it would be greatly appreciated. jiggs.....

I had this cam in a 65 dodge coronet 500 426w 4 spd  back when I was in High School pulled hard  nice lope  worked well with a stock 440 intake worked great with a Edelbrock TM7 intake and a holley 3310-2 750 carb.  I still have the spec sheet  that came with it.

465 int  465 exh  228 degrees @ .050  278 duration  62 overlap
