Hey Paddock,
I'm heading down that slippery slope (already started) and been looking for information/opinions on case and crankshaft modifications. I already had my case boat tailed and was looking to complete the task by having the crankshaft knife edged. Then I found this article from Neil at Performance Development. http://performancedevelopments.com/living-on-the-knife-edge/ Sounds like he's legit and I haven't done crankshaft mods yet. Thinking I should leave it be. (IMG:style_emoticons/default/beerchug.gif) Shane |

I think I'm going to pass on the knife edging. I already plan on spending money on heads, induction, etc. Making power to run in either ST3 or ST4 is the plan.
NASA ST group is a builders class so with good planning you car can be at the top of your class. My driving skills is the real problem! (IMG:style_emoticons/default/headbang.gif) I plan on doing the groove and cross drilling to the crank. That seems like a no brainer. Hopefully it doesn't need too much more work. Its been sitting at my dads shop for 25 years. I mean how many hours could be on this thing?? |
