Pierce has a Pro Power RY 45. I've read HP figures in the mid 900s, but their Dyno numbers have always been high.

Yep, about 90 HP to high

Bronson, Davenport, McCreadie,Josh Richards, and Owens, and Bobby Pierce were using D3 headed Ford based engines. Pierce did have a Pro Power D3 Ford. Bloomquist was the only one mentioned who actually had a RY45 engine. All except pierce did have engines built by Durham .

Why do they use old technology D3 vs. RY45 wide bore and GM wide bore?

[Krooser]

Does GM actually build a wide bore block?

No not that anyone can buy. the r07 used in nascar is the only 4.5 block that gm makes and they don't have it available for sale to the public new. At least not last time i looked

Seems, a lot of people put too much in to this engine deal. It is seldom, you use all of your power. Just at a handful of long tracks. Most detune these big spread bores, most of the time. Old school is, match engine to the track. Smokey Yunick once said,"A good engine is one you can set at 8k on the Dyno and go to lunch and have it still running, when you get back.". That is a good engine. However, he was one of the early builders, that paid attention to power curves, more than outright power.
