@0.50 its about 198 duration, what do you want the car to do? what other mods are you going to do? You want to compare cams @0.50 and not advertised duration, you also want to look at lift and duration at all points, opening and closing rates and LCA and match it to your combo.
Greg, so how did you like the performer cam? Did you notice any power/speed improvements over stock?The camshaft that I had in my car was an Edelbrock Performer-plus. I have a cam with 448 lift exh/int and 204 duration @0.50 and 112 lobe sep. Smooth idle. Now if you want a replacement with slight upgrades in torque a Comp 240H will do the same.
So which one do youthink gave more pwoer, the Performer or the 240H? Ive never seven seen a 240H, only a 250H.There was a noticeable difference in the torque and pulled good up to 5500. I had a idle issue that haunted me with this cam , but others I have talked with have had a smooth idle. There are better choices than the Performer. The 240H cam out because the shop never used any EOS for the break in and I had the cam lobes chew off. There is an article on this site with the 351 cam upgrade with the Performer. The High Energy Comp Cams are a very good upgrade.
the performer cam idles like a stocker and doesnt give much in hp just TQ, the 260h sounds close to stock in a 289 and gives a nice power bump even at low end as it is ground 4 deg's advanced. The 240-250h are better in heavy cars/trucks.
