I do that too but, I usually leave feedback after I get product in and not 8 months down the road......would be nice to see some longetivity feedback...
I would love to change to a solid lift cam and this would be a relatively inexpensive way to do that.....

I've never heard of this company before but I don't know anything about Australian speed companies but they do some heavy duty racing down under. They look like quality part and I would consider these myself. I used Australian made solid lifters in my 390, can't recall the name, but they where nice quality and have had no problem.

If T&D were what $1100 or so? Then the price of these should be a good indication of what they are.

It would be really good to find a few people (here preferably) who have actually installed and run these things. According to eBay, they've sold a bunch of them so that should be possible. I am skeptical of online review systems that can be "gamed."
The stock design will break at the unsupported ends when used with very stiff valve springs at high RPMs. This design addresses that weakness. Otherwise, the non-adjustable stockers are quite durable.
These new rockers are adjustable and will require all new pushrods. Note the inclusion of two adjustable pushrods that are used only to get the proper length of the new pushrods. I suspect that oiling is changed (comes through pushrods) and, thus, one might want/need to restrict oil flow through the heads to get more oil pressure to the crank.
American made rocker arm assemblies that look just like these will run around $1200.

After a further bit of research, I found the following PRW rocker arm assembly for a MSRP of $729.50. As well, I located a well done article on installing them here which tells me that the oiling scheme remains the same so my concern about that was unfounded.
