how long are the stock rods vs a 4mill stroker rod?

stock rod length is 110mm you can get a 4mil with 110mm or 115mm rods, the stroke is the length from the center of the crank to the center of the lower rod pin

stock rod length is 110mm you can get a 4mil with 110mm or 115mm rods, the stroke is the length from the center of the crank to the center of the lower rod pin

Actually the stroke is the distance from the center of the main journal to the center of the rod pin TIMES 2.The stock rod are 110mm. You can get 110 rods on a stroker or a stocker, you can get 115 rods on bothe a stocker or a 4mil stroker.

so if i get this right a stock crank with a 115 mm rod would be the same as a stroker crank with a 110 mm rod

no. stroke is how much the rod moves. that's the difference between stock and stroker. rod length sets how far away the piston pin sits, which uses different pistons.

oops forgot the times 2 I stand corrected

i cant believe how many times i heard that a 115 rod crank was a 5 mill stroker.. back when i was doing the long rod 350's for mx use. but now in all reality i like the short rod motors in the smaller cc.

 

longer rod is just that a longer rod to get a stroker yo have to move the pin around.

[AKheathen]

yah, long rod is good for longer dwell and more direcet angle, which is favorable tward mid-low torque, but shorter rod is better for shorter dwell, better allance and less weight, which translates into faster and higher reving, and topend power.

ok thx for all the info guys
