I'd have to dig up all the receipts as I've been piecing together all the parts a little at a time. The most expensive single purchase for the motor so far has been the CP pistons. I had a custom set made for the stroker shortblock. They are sexy to look at and are designed with valve reliefs for up to 0.600" lift cams. Honestly I used to have a spreadsheet with every part that I bought, itemized even separating labor from parts cost, gas, car washes, ect. The numbers started to get so high that I decided to stop counting because I could put one hell of a down payment on a house!
