Very sage advice from Buzz in post #64.
I have a sideoiler built by Brent Lykins. I asked Brent to make it streetable and perform well at 2000-4000 rpm with a broad flat torque curve. It dynoed at 580 hp and 659 lb-ft, and I have no problem with it from stop light to stop light. It has a great lopey idle.
Unless you specify good street manners, most engine builders will give you something that is more suited to running flat out on the track. You will then be changing the cam to try and detune it.
Since you live in Florida, get the big cooling option, and don’t use an
oil cooler. Mine is plumbed for looks but not used.
