how many horses?

Just add everything up. (This is what the machine work cost me, I think the place I went is a little on the cheap side.)
I started of with a complete stock engine-$50
Reground the crank-$90
Cylinder bore-$125
External Balance- $125

Those Keith Blacks- $190
Purple Cam- $170
Plus Shipping

Theres over $700 in parts and machine work there. Plus you have a sex of x heads, which are pretty pricey these days, a windage tray, bearings and rings. How much its worth to you is a different question. Did they do any other machine work? Have everything magnafluxed? Check the rods? Deck the block?
