What is the general consensus on RB cams. I have read a lot of people swear by them and others say they are old technology and more modern cams profiles are better.

There is a book on big block mopars where the author says to look for a hydraulic cam with duration @.050 that is 85% of advertised. On a solid look for 90%. This is supposed to indicate an aggressive ramp/lobe profile. I have looked at an RB ssh-25 cam with [Email]238@.050[/Email] and 285 adverstised. Its 83.5% does this mean its not ground to take advantage of the .904 lifter? Most to the hyd cams I have looked at including the Comp and Lunati cams that are supposed to be ground for the mopar lifter do not come out to be 85% or more either.

I guess I should just take the cam grinders word for it. Who to trust? What are peoples thoughts about Jim from RB?

Well I can say that I love the Racer Brown cam I run in my 340 car goes like a bat out of hell! Idles great with good vacuum and will pull to 6500. and too top it off gets close to 14MPG with 4.10s and 25" tires to boot. A clown in a newer vette found out the hard way recently that a 340 is no punk from a dead stop.

Check it for core shift after it's installed in the block, with the gear on and the lifters in. That's probably good advice with any cam.

I am very happy with mine also, it is in a 340 dart, very mild grind, with less advertised duration than the stock cam but it will run 13.7 at 102mph with 3.23 gears and stock exhaust, plus I can get about 18+ mpg on the highway. I will go with them again on my next motor.

I'm happy with mine, Jim is very easy to talk with.

I ran the SSH-38 for while then stepped up to the SSH-44. Call Jim and talk to him about your combination. He's no stranger to Mopars.

Jim was very helpful and informative for me on a solid cam

The one that he ground for my stroker is awesome.

Small blocks like this cam either in the regular version 340-360 or the stroker version 408-416
