When I had the GTP stage 2 heads, Lingerfelter 211/219 ( manual trans version of the 219/219 ) and mac shorties with PCM4less tune my car was cleaner on the sniffer then stock. PA inspection. The cam made tons of torque thru the midrange, fell a little stort about 5K. Dyno 327HP 320Trq at the wheels around 5K then fell off. If you looking to play and not about ETs that's a great cam.
The 503 should better those numbers.

The 219/219 is an excellent choice for a street driven SBC/LT1 that needs to pass smog.
Have that cam in my 84 (90 L09, Lingenfelter CNC L98 heads, performer RPM with factory CC q-jet), and it passed NJ smog back when it was more stringent. Never dyno'd it, but it ran 12.5 at 113mph all day - so about 395-400hp at 5500 or so and around 425lb-ft. Feels like a strong 383 down low due to the smallish heads and (luckily) good combo with the cam.
I'm sure the 211/219 would work great as well.
