Wow, I am I glad to find an active Mopar forum! I'm the in process of bringing my street/strip 440 powered 76 Volare back to life after a long sleep. I've got two motors, the first is my spare, a blueprinted .060 over TRW motor, 9.5 CR 456 heads pocket ported with the templates and port matched, the cam is Mopars .557 lift mechanical. The thing made 520hp and 543trq good enough for 11.50s in the Plymouth. The next is a .060 over 4.15 stroke that I built in 91 with a Mopar crank I waited a year for, no kit, light weight custom pistons floating pins etc.. The heads are 915s that have had the same porting as the 456s and the cam I had used was a Comp .650 lift, 290 duration @ .050 lift. This combo pulled hard to 7000 and was good for 6.70 1/8th mile and 1.43 60 foot times. As tempting as all the new parts available now are I've decided to just freshen up this combination with one change, the cam. In an effort to lower the rpm range I'm thinking about taking 15 degrees out @ .50 lift and I happen to have this Mopar cam. http://www.summitracing.com/parts/dcc-4349268ae/overview/make/dodge So my question is has anyone used it in the past, and had it on a dyno, I'm interested in the power curves, like, dislikes etc.. Whatever cam I use it will be a flat tappet. Ihanks for any input, Tom
Have a great day Iowan

My intention is to keep the thing under 6600rpm, I'm more interested in making this old bullet survive than go a tenth or two faster. This motor will go on the dyno after it's done, the one thing I'm concerned with is the curves being to early. I can always use the Conp cam if I don't like the numbers.
I tend to sand bag when bracket racing by a tenth or so, after all how fast is a old Volare anyhow?

With that low an rpm, maybe a hydraulic roller would be a good choice. Maximum torque with a lowered usable rpm range. Low maintenance, not as expensive as a solid roller setup.

Cool!! Another Iawegian on board! What track do you plan on running? Well I'm 45 miles from Cedar Falls, 85 from Humboldt. I like them both but I favor Humboldt for reasons unknown.

Since you have the cam already, why not stick it in, shift it at 5500 and see how it goes. That might be pretty close to what it will want, depending on the rest of the parts. These big motors with such poor flowing heads are stump pullers, for sure and don't need to be revved very high for best results
