It's not going to happen.

I'm sure someone can with time and money and skill.

600 hp x 5252 / (273 cid x 1.4 lbs-ft per cid x 90%) = 9,160 rpm, I'm sure someone can build a 9,000 ish rpm 273 engine that up around 1.4 lbs-ft.

Just remember you have to do it with the same heads that were used on the 400” combo……. Which could easily be some ported SM heads(and not the best ones ever seen either).
Off the 400 and onto the 273……. No reworking.
