I remember back in the 90's when the small block stroker scene hit, i was really into the foxbody mustangs at the time. Every kit that you would see advertised for sale would list its rod/stroke ratio. But nowadays you don't even hear about it anymore. Why is that. Is it not as big a deal as it was once thought to be? Or is it because that most kits sold are marketed more toward high performance, assuming a higher cfm flowing top end.
I'm no expert but it is my understanding that a longer rod tends to make better power when used with "bigger" heads, intake, cam...etc. and the shorter rods perform better with more velocity at a lower rpm. Is this correct?
If so, what about other applications like towing were you want more power down low or performance builds using factory small port heads and/or intakes. Wouldn't they benefit from a shorter rod?
For instance I've been thinking about a 428 street build, standard bore and a 4.125 stroke using a 6.535 or 6.385 BBC rod, a relatively square engine. Using smaller port heads and intake for good velocity (TFS, or maybe stock iron) , not too radical of a HR cam and a good intake to match (streetmaster/ dominator or ?). How would the shorter rod perform vs the 6.7 or 6.8
