406 Hydraulic to Solid Roller cam results
406 Hydraulic to Solid Roller cam results When I first had my 406 on the Dyno it made 545 rwhp. I had my old drag radials on the car for tuning. I replaced my drag radials and with the new drag radials on I put it back on the Dyno and it made 526 rwhp. The new tires were stickier and softer and wrinkled more during a pull . Both sets set at 25 psi.
My original cam was an old comp cam grind for a stroker.
247/255 624 /624 on 114LSA
The solid roller is a cam motion grind .
250/266 680/642 on 114LSA , .010 hot lash
The solid roller made around 20 rwhp peak than the Hydraulic and carried to 7400 before it started to fall off.

Thanks guys. We tried another degree of timing for Pro Stock John. It was just enough to get me over 550. It was worth almost 3 Hp! Where the hydraulic fell off I'm up 30-40 with the solid roller.
I'm planning on moving my shifts up to 7400.
