What is everyone using for as a gear ratio
masracingtd1167:
Why are everybody afraid of rpm ? A smallblock dose not really make any power till it's over 6000rpm ! My son's 565 big block crosses at about 8500 Just sayin .
MaggiFinn:
I run 5.43:1
32" tires for the strip and 34.5" in the sand.
I rev the snot out of it.
jspell:
Cajun...what rpm through the traps?
Cajuninjector:
Quarter mile is 8400+-
That's not too high in jr fuel though. Some shorter stroke motors cross at well over 10. Maybe pushing 11
I've talked to guys that have 7" converters that stall over 8000!!!
All boils down to $$$
JrFuel Hayden:
I posted allot of info on this subject, but it's not here ?
Most Heritage Jr Fuel teams have 7" converters, and most stall at 8300 to 8700, except Park's which stalls at 9200.
And yes we shift at 9500 to 10500, and cross finish line about the same.
But I'm sure that's not what you are looking for.
Maybe my post with tire, gear, converter, and motor combo recommendations will show up later.
Too bad. Just trying to help !
