Save your breath, you wont get anything thru to these guys.
Most hemi rams run good, some are slower than others. My bet would be on the hemi.

Most Hemi's run OK, nothing real special about a low 16 to high 15 second truck. The Rams the Hemis are wrapped in weigh around 5,000+ lbs. The Vortec 350 is a strong running engine and is only 60 hp short to the tires compared to the Hemi. Don't count the L31 out of the race. I have seen ECSB C1500s with the L31 and 3.73s run 15.9 in the 1/4. If the Ram has 20s on it, you may have him in the bag. MANY Rams with 20s came with 3.55 gears. The factory P275/50/R20 tires are 33" tall and the effective gearing is taller than a Chevy with 3.08s and 29" tall tires. I am a service advisor at a Chrylser/Jeep/Dodge dealer so I am around these all day long and know what they run like. I even choose to buy a 4.7 when I got my truck, because its only a few tenths in the 1/4 slower than the Hemi bone stock and from a 50 punch is actually stronger than the Hemi as it holds 2nd gear prime to a higher speed/rpm than the Hemi.
