No problem here on my end that is why I opened up this discussion in the first place.
So besides the class restrictions for the 170 compared to the 198/225 Why do you like the 170 so much
The main reason I like the 170, is that is what I had when I started racing slants in "stock eliminator" way back when. I just ran what I had, and had many 170 spares. I am a "low dollar" racer. A 170 is actually a little "trickier" to build then the 198/225. Piston to valve clearance is an issue, no budget "race" type rods. Only headers available are the Aussiespeed. I have run the 225 engine ( never ran a 198) and have run quicker in the same car as the 170.
