We purchase this kit frequently from a distributor and found out real quick when vito's price increased. I'm not sure why Vito's hasn't change the price on their site, but unless something changes for the better you'll see the price increase soon. The companies who buy 1-2 a month will not know right away about the price increase. The only distributor I know that is still displaying the old price is out of stock, so we aren't able to buy any kits at the old price unfortunately. We purchase the kits below standard dealer price due to our volume and at 499.00 we wouldn't even be able to cover return shipping if something in the kit was missing. We are geared towards customer satisfaction and service and not price cutting everyone trying to support their family. Regardless, 615.00 will not be the retail price soon on Vito's website. We give back to the community as often as we can. We might be one of the few vendors here that give back to the owners to keep this site rolling. I'm not sure why your attacking us over one pricing debate. We can not control if Vito's doesn't update their site or that our distributor raised dealer cost and retail. We appreciate everyone who has kept a level head, and gave us a benefit of a doubt. I do not like posting in other people's for sale thread, but I thought I needed to respond to AWK statement. Sorry to keep rambling.. Other BIG BORE CYLINDER AND HEAD KITS from Marshall Distributing, Inc . This is the place we purchase the kit from. As you can see the retail price has been changed. Lets do some rough math work @ 20 percent off retail.. My Mistaken Retail Price in the deleted thread: 669 x .2 =133.8 (535.2) Listed Price on our site until tomorrow 535.88 which is a little over .80 cents below 20% New Price : 649.00 x .2 = 129.80 (519.2) Our new Sale Price is 519.20 shipped anywhere in the lower 48 states maybe cheaper depending on how many kits we buy at once. Old Price: 615.00 x .2 = 123.00 (492.95) Normal Forum Special Shipped Price 499 until the vendors try to re-stock the kit. $6.05 more below 20% If we was comparing apples to apples we would have been competitive with the normal going forum rate. Whether it's 499 or 550 it's still cheaper than either the new or the old retail!
