Re: "Square" Engine Practical ??

325 HP 396's aint so mighty chief! THAT was my point. 327s had it all over them. Not a "square bore" issue in the least. The real point.

396's small bore shrouds valves badly. Once the 4.25" bore blocks came out, everything changed.

Re: "Square" Engine Practical ??

I know of a 4.25" stroke "square" engine that made a tick over 800 HP at the crank and runs high 9's on pump gas.
FWIW...

This is just out of curiosity, not looking to build one.

At some point in the past, I read an article about "square" engines. I only remember it due to them being named as such. If your not familiar with the term, if I remember correctly, a square engine is where the bore and the stroke are the same?

I believe the article alluded to, that these engines can rev much quicker then those with the more common bore to stroke dimensions. So, are such engines practical on the street? Or, are they more at home on a track?
In my mind, an engine that can rev quicker would be at an advantage on road courses, autocross tracks, and maybe even on the street, since theoretically, said vehicle should be able to increase their speed at a quicker rate then their competition running the more common engine bore to stroke differences, with all else being equal?

Am I missing something? I've searched google for "square engines", but I am not getting anything. Anyone know where I can read up on these engines? Maybe using the term square is not correct?

Thank you in advance.

The only reason someone would want insurance is if they want to pay someone elses bills or want someone else to pay their bills.

BIGOT is a word used by people that can't use logical reasoning to prove that you are wrong when you don't agree with them.
