So your Dad does have the 5 speed SHO.
Even though I don't like Fords, that is a fast car and handles very well for a stock car (with the right tires)
Definitely a sleeper and about 400 lbs lighter than the Aurora with a trunk that is just a big.
He will be hard pressed to find another one quite like it.

Maybe he should buy the 99 Olds for church on Sunday and keep the SHO.

come on
Your Dad'* 3.0 L Yamaha engine likes to rev. No power below 4000 rpm though. It probably has a lot to do with having 4 valves per cylinder and dual intake runners where the GM motor has only 2 valves and a single intake runner.
Those SHO'* will rev to 8000 rpm stock, where our 3800'* will only go to about 6000 rpm (7000 rpm with mods).
The Aurora has 4 valves per cylinder but it is a larger engine, so no need to rev above 6000.....way more torque than the SHO.
Sure the SHO has 4 valves per cylinder, but actually, the short runner stays closed until around 4000rpms. The torque curve is pretty flat from a little above idle until it drops off right before the rev limiter. (7300rpm stock- but the motor'* good for a lot more.. )

Peak HP is around 6000rpm.

actually... the Series II 3800 (supercharged or not) was designed to turn 7000 RPM. the reason it'* redline is so much lower is because of the transmission, it is only good for 6500 RPM out of first, 6250 out of second, and 6000 out of third. and apparently they didn't want to program it to shift out of 1st and 2nd at different RPM, so they just took 6000, and made it shift there

Actually 7k on a series II will break it eventually. We were talking with some guys who are installing some of the best Intense mods into a GP for a friend in their club. It has an MP112 blower, custom intercooler, etc, and they say that after ALL the upgrages (everything was upgraded) they are still worried abuot going over 7k rpm.

GM has spent millions of dollars on research over the years. I'd trust them when they say what the engine should be.
