Starting my engine build.

I don't know if I would trust .030 on a motor that will make power to 6k and beyond. Maybe a stock Gen 1 or 2 setup that doesn't do much past 4500 RPM, but gen 3 top end = higher RPM = more rod stretch.

Well if you can get away with .040" quench on a 4"~4.3" piston then .030" quench on a 3.7" piston is not unreasonable. The reason you need a safety margin is for a bit of rod stretch and the piston rocking in the bore. And the smaller a piston is the less these variables will be a problem.

That's a nice looking 'bird, good luck with the build

Thanks!

I haven't purchased any parts yet, Im saving paychecks so I can buy everything in the bottom end at once.

What fuel are you planning to run with 11.5+ compression?
