Rod Ratio?
How do you exactly calculated? I do have a rough idea, but I would like to confirm. Also what is the rod length for the following engines.
b16a
b18c
b18a/b
b20
Thanx

Re: Rod Ratio? (Screamer)
I am working on finding the rod lengths but the strokes are as follows:
B16A2 3.05 inches 77.5mm
B18B1, B20B4, and B20Z2 3.50 inches 90mm
B18C1, B18C5 3.43 inches 87mm
All the 18's and 20's have a rod lengh of 137mm.
I cannot find the 16 right now....if my calculations are correct they are 135mm
R/S ratio
B16 1.74:1
B18B & B20B 1.54:1
B18C 1.57:1
