I was going to run 440 Source, they were 499.95 each I went to order them and they said price went up. I had the ad in my hand and they didn't want to honor it. Fine it's their prerogative. there are other options. and as a matter of principle I used my Iron heads. So since the car is just a street cruise and had all the parts I went and did those. for Engine parts I now deal with the Ed's at Molnar and Ross Pistons and TFS for heads. Outstanding service and products and they stick to their price.
