anyone have more info on this cam??
I'm looking for @50 info, separation, etc, and maybe idling/performance characteristics from others who have run this cam. It's a purple hyd 296/.521 with 108 centerline and 80 overlap. Running it in a 328 with hyd roller lifters from '85 318 and 302 heads with SP flattops, Dyna ceramic headers, 10.47 CR. Thanks for the info ahead of time...

I could not find it In my catalog, Sorry! I will tell you this for sure With 80 deg over lap I suspect the power range about 3000-7000 RPMs. And will idle like my 360 with 3 dead plugs!

That may actually work out well as it's going into a tunnel rammed SB w/ 3000 stall. Idle may be a bit choppy, but with a 108 centerline and being hydraulic, it shouldn't be too bad, should it??

The "237" (292/509, 76 lap, 108 CL) slobbers pretty bad in a 440. I imagine 80 overlap (both open) in something approx 110 inches smaller displacement would be rough with capital letters.

I have a '96 Mopar performance catalog that says the following under cam spec grid... Note: To calculate duration at fifty, multiply advertised duration by .850 - do not use for selection. If it help any. Robert |

Belive me and others with 80 deg overlap in a small block..........will be very nasty. And probably foul plugs all day long. That cam is made with definate bracket RACER in mind, with ZERO streetabilty!

Ya and with 10.47:1 comp. ratio it'll be a turtle off the line. You should have more like 11.5 comp. with a cam like that. Matter of fact your little engine will work way better with a 280/.480" cam. Even the 292/.509" will be too hairy........djs

I had a cam of about that lift and dur. .532 lift, in a 390 with 13.5 compression ratio, 4 spd. '67 Mustang. It wasn't good on the street at all. And that was back in '71 with the good gas back then.
Stay below .490 lift and .230 dur. at .050 lift. about these, with 10 to 1 ratio. You'll be much happier. |

So, you guys believe that I would be better off using the PAW house grind 304/.454 with 108 centerline and 225@50 that's in the garage?

Na, dont run that thing. Go with a good cam like around 230 dur@.050 lift and around .500 lift for all out street machine performance! It will be streetable properly tuned.

No the .450 lift isn't going to make you happy. .304 dur. isn't going to work the way you would want. Get one like 6 packin says.
Mine is .222 dur at .05 lift and .492, 114 centerline and works great with 9.67 true compression ratio. 4 spd |

We've got the 292/.508 cam in my kids 318 daily driver with a paltry 8.0:1 CR, 360 heads, M1 single plain intake and 780 VS carb, but with a very loose 4400 RPM converter. It's a pig on the street. Plug life is decent with an MSD though and it looks bad and sounds bad, just not very bad at all except for fuel mileage which obviously is a joke at best. Don't flame me though, this was designed this way on purpose. To sound good but not really be all that fast. It doesn't run as bad as you would think though.
I'd say you could use that cam with a higher stall converter although something with about 230 degrees and .490 to .500 lift would probably perform better, but then so would a single four barrel on a dual plane manifold like an RPM Air Gap. But I suspect you are going more for a show type car that has sound and visual impact rather than performance as it's main thing. In which case go ahead and stick the lumpy cam in. |
