My lifters out of my 2000 hp500s are singels with a guide plate that lays in the block to keep them in line, as i been looking at new replacment lifters they all have a tie bar across the top of them in pairs, will i still need the guide plates with new lifters or not.

Rick,

No you will not. The vertical link bar will maintain the orientation of the lifters.

Thanks bob and ill be ready to order cams next week or so ill give you a call.

rs,
There are replacement lifters available that use the factory "dog bone" retainers. They are also usually a little less expensive than the link bar type.

If at all possible, use the stock replacement lifters. They are some of the best that you can buy. I have only seen one of those lifters fail out of thousands.

could i just reuse them as they look fine , how many hours would you run them, i use royal purple sythetic oil every 20 hrs.

where can i get the stock style, mercruiser or aftermarket?

In a purely stock engine they should be good to 500-600 hrs. You can buy them from Competition Products. 920-233-2023

That's an interesting question above. I know you should never re-use flat tappets on a new cam, but can you safely re-use roller ones on a new cam - or is that a big no no too?
Thanks
Matt
