Can someone tell me if all one piece rear main blocks can accept OEM roller lifters? This is the one I'm looking at http://store.summitracing.com/partdetail.asp?autofilter=1&part=NAL-88962516&N=700+400129+4294925232+4294839078+115&autoview=sku
The description states that it has "a lifter valley designed for hydraulic and flat tappet camshafts and lifters" which must be a misprint because it doesn't make sense to me.
Thanks

Appreciate it Chad. Looks like a better price at that site too!

If you look carefully (and assuming the pictures are correct and accurate and match the part) you can clearly see the bosses for the "spider" bolts on the can tunnel of both blocks.

Rich,
Not all of the one pc seal blocks can use factory roller lifters, but the one you are looking at certainly can. It is based on the late model production block.

By the way, I think you can get the Dart SHP block for about the same price and it is a 2 pc seal type block.

Thanks Bill, that's something to think about. It would give me room to grow in the future.

We have seen those blocks before and so far I have not seen one with nodular iron caps GOOGLE that and you will see what I am talking about.
