$2500= freshening by Jeff Claxton
$7000= same freshening Gaerte, kistler, Ect...

These Prices im sure arent acrossed the board just my personal knowledge and exp... with cost and builders.. I personally would us Jeff Claxton over the others even if they where that same price!

Same Work, Parts and Same performance in my opinion!
I understand every engine need more or less work.. im refering to a mid-season Freshening..valve springs ect...I try to get 35-40 races before we get into Pistons Ect..
