Another thing that ****** me off is the fact that basically no one with an old car seems to understand that just because their car came with 400 horsepower stock, that isn't measured at the rear wheels. Now, obviously there are exceptions, but a lot of people seem to think that horsepower is all that matters, not traction or anything else.
Like the other day I told my dad that my car dynoed 409 RWHP, and he said "Is that it?"
I hate racing old cars.

Here is something else to consider. Engines rated at 400HP(SAE gross HP) before 1972 would be approx. 320HP(SAE net HP) by todays standards(approx 20% less). Then, minus another 15 or 20 per cent for rwhp. That old muscle car may really only have 256 to 272 rwhp. So, when someone tells you their old stock muscle car had as much HP as your Viper, tell them to wakeup because they are dreaming. In a few cases, the factory under rated the HP, but still not likely to beat todays engines.
