    how fast can we go roundy round

    *NEW EDITED POST* Governor springs aside what part of these engines would be the limiting factor on how high of RPMs they can turn? My guess would have to be the the stock bolts holding the connecting rod caps on would be the first part to let go. In that case a set of stronger rods with studs...

    short gears and tall tires ?

    i have read that running gears shorter than 4.10 or tires taller than 35" can cause pinion failure in the 10.25. I know some guys on here have done one or both of the above and wonder how there pinions are holding up. I have a project i slowly am building and plan on running at least 4.10 gears...
