There is an interesting hydraulic roller that 440 Source has that is a custom grind from Comp Cams. It's a 571 lift and a little longer duration for 500" engines with good flowing heads. I was looking at a 588 for my 493 with EZ's but I may go with this 571 instead. Duration at 50 is 252 In and 258 ex 110 lobe center Gus

242/248 at fifty is more like what I'd use in a hot street 440. Small for a street/strip stroker IMO.

I've had a couple of friends have problems with the Comp hydraulic roller lifters. Go with the Howards lifters. I use this cam and it works really well on the street: https://www.summitracing.com/parts/hrs-723445-10

I'm putting together a 493 stroker. 10.5:1 compression, indy ez heads, mopar single plane intake, going with a hydraulic roller cam. looking at the comp extreme energy cam duration 292/300, lift 549/544. is it descent? will it have a good rumble? don't want it to idle like a truck lol. I used that cam in a similar 505 for a customer. Trick Flow 240 heads, 1.6, rockers, 10.1 CR, and Indys dual plane manifold. It sounded healthy, and made well over 600 hp on 91 pump premium.
