If Indy and Formula 1 cars were racing on the street from 1500-5500 rpm, then they'd have big blocks.
Funny, I've never heard 427's being known as "rod breakers"
Your top fuel alcohol dragsters are not running small blocks, I can assure you.
BTW, bigger bores do not require longer rods.....longer strokes do.
Misinformation yields lots of confusion.
