What can I say but this David guy is very deceptive - Called and asked for a price on a 300 CID long block - $650.00. Then asked what is would cost to have it installed - $1699.00. Said OK. Next thing, David was quoting $5400.00 for extra parts? Got a list of these extra parts needed - like $31.00 for (6) spark plugs and many other 2-3 hundred percent marked up items? Asked if I could supply the "extra parts" said it would void my warranty. Make a long story short, even though he came down to $2900 (but would not give a list of what they were going to do, and said it could still go up in price) I decided to pull the truck and went to Thunderbolt - They gave a firm quote and stuck with it.
