Im in need of some help identifying which one of two cams would be better for my car they are both out of 305's the first is older and the only lettering i can find on it is EPI or EP1 its hard to tell and the lift is .285 int/exh roughly
(I used a vernier I just dont trust my measuring ability) i dont have a degree wheel or anysuch thing to measure the duration with the second cam is much newer (manafacture date on the end says 11/26/04) but seems odd because the lift for the number one cylinder is different that the rest 2-8 all have .305 lift number one has .320 not sure why this is or if this is normal whichever one is chosen will be going into a 79' 305 block bored .010 over, street dominator manifold (high rise), edelbrock thunder series 500cfm carb, headman headers, dynomax cat back, accel dist/super coil. this is in a 83 z28 a new cam isnt out of the question if niether of these will work well for me it needs to be streetable but i would like to stay more on the performance end with a moderately rough idle any info/advice would be very appreciated
