Camshaft throwdown

[K.O. SWINGER]

So even though Mopar performance camshafts have been discredited in some people's opinions I am a fan of the old DC grinds when used in inappropriate combinations. My question is how would you feel these two camshafts would perform in comparison to each other. One is a hydraulic oval track grind the other is listed as a flat tappet also on the oval track competition list. What would you expect the differences in performance and ranges to be between the two I have my ideas I'd like to hear yours. I am currently running cam A and will be switching to camshaft B. But for fun our hypothetical test mule will be a 360 flat top pistons pro Comp heads air gap and 750 Holly DP with the other usual upgrades. Camshaft a is hydraulic camshaft b is solid lift

After lash the mechanical will have about the same lift as the hydraulic as they both are .500” lift rule cams, you’re going from a 108 LSA to a 106 (both recommended on 106 ICL) not sure how the actual “advertised” duration at various measuring points compare as well as the duration @,050” The hydraulic is supposedly good for 1/4 mile flat tracks and the solid for 3/8 mile flat tracks. So on the surface the solid should pull (rpm) a little longer, just how much harder depends on actual timing and where it’s installed compared to what you have now? Have you measured the current cam to see actual opening/closing points?

I've only used mopar purple cams and have been happy! 1st was the 280 mopar cam. Now switched it for the loved and hated 292 purple shaft. I installed it 4° advanced at the crank and in my 360 does pretty well.

No , I always advance my Mopar cams three or four degrees.

I ran the 292 cam previous to the 288 cam they perform pretty similar with the 292 having a little bit more top and and the 288 seeming to have a stronger mid-range coming on a little sooner, pretty much what you would expect.

Two benefits the solid will have: the lifters will not pump up & lose hp; & the lifters will not bleed down.....

Just to be sure because that picture is blurry and so are my eyes. Those cams are the Hyd 288/.497 flat 3/8 oval track cam? And the solid 284/.526?

I ran the Hyd 288/.497 flat track cam for a while. It had some really good low to midrange torque. The idle chopped like a lumber Jack on crack. Lots of over lap on a tight center line on a low install intake center line.
