There are so many variables involved, that a blanket statement like such simply can not be made.

I used to subscribe to this idea that long strokes killed revs, but I started to have doubts when I bought my 2003 Lightning with the 5.4 modular motor that is about as undersquare as you can get. Then I bought a Coyote engine Mustang GT, which again is undersquare and zings towards it's 7000 rpm redline like no body's business. That pretty much killed the myth for me. Also, my 4.25 stroke FE seems to rev just as strong as my 3.75 stroke Chev 427 - well, at least up to a point. |
