All those engines I wrote about were warrantied for 2 years and they only came back for broke pistons (and not covered) if they were sprayed by a dummy.
Sorry man. I didn't mean any disrespect to anyone and I didn't think of anyone in particular other than making a general joke because I've watched guys pick up cars from the dealer and thrash on them right off the lot with new engines and also put them right on the dyno with minimal warm up time. Seriously just a generic statement. The fuel thing is because I don't know too many people that take the time to buy the proper fuel for high performance cars. It's just too inconvenient for most.

My car ran some casual 10 passes because I corrected some of the original install power robbing issues and stuff. Basically it was set up better than how it was delivered.
Fuel delivery with 8AN tank pick up to carb
Aeromotive fuel filter
Properly tuned carb from Pro-Systems
Larger surface air cleaner
Different headers that don't cover 1/3 of an inch width of each exhaust port
Side pipes with a bit more flow
Drag radials to start from idle and have 1.7 or 1.8 60ft time
Different half shafts
Detroit TruTrack rear end with 3.73 gears
Light weight flywheel
1/4 tank of gas for less weight
Lower density altitude
100 octane unleaded fuel on Roush original timing

If anyone can let out a clutch from idle, press the gas and shift through gears they'll run a high 10 on a well prepped track with drag radials, 2450 race weight and 475 wheel HP.

Something that's a common misconception is that a casual start drag pass is hard on the car when in fact a few seconds threw the gears. It's not a big deal on a proper air fuel ratio. Its a few seconds not much different than a romp through the gears entering the freeway. Alternately more damage can occur from things like sustained hard load to store heat and particularly on a lean air fuel along with pinging. Throw in a cold new engine to start and wow. It happens not because people want to cause damage. Generically speaking many just don't know.
