Darton sleeved LS2 454 vs RHS block 454 Just poking around the interwebs today, and I came across a company that offers an RHS 454 shortblock for nearly the same price as another company has for a Darton sleeved LS2 454. The only difference is the block, both companies are using Callies Compstar/Wiseco internals.
Any advantages to the RHS motor vs the Datron sleeved LS2 or vice versa?
Just curious if the RHS motor has the same cylinder length as the LSX, or if it is longer like the Darton sleeves.

You might want to check the thread in this forum "Sell me on a sleeved block" to get some opinions on RHS blocks.

The RHS has some other advantages too though, like a raised cam option if you want to use even more stroke, billet mains caps, and 6 bolts per cylinder for the heads.
IMO, there may not be any real noticeable advantages between the two of they're the same price, so I would lean towards the more reputable builder and go with them.

The RHS does have the longer sleeves like the Dartons, but they're made with grey iron like the stock GM blocks, which have been able to take some abuse. The Dartons on the other hand, are made out of a stronger ductile iron, so they can potentially handle more power.

AL Blocks 319/356 Hi All, The LS-2 AL Block Alloy is 319-T5 which is weak.
The RHS AL Block Alloy is 356-T6511 which is much stronger.
I have made Al parts out of 206, as strong as a forged part.

If I was using an Aluminum Block for a serious build.
I would use the new one that CBM,BTR, & TSP offer,
Among others.
USA Made and Finished.!
4.200" Bore Capacity NA,
Priority Main Oiling!
A requirement for me.
Best Aluminum LS Block available for those 3 reasons
alone, and their are many others.

Also, do you know what they are using for sleeve material. I could have actually saved money by using one, vs. my RED sleeved, Katech billet main capped ls2 block....

AL Block Cam Bearings Hi F-2000, when GM delivered the BBC 510" Can-Am block (AL), there were problems with the Cam Bearings that were fixed by the Crower Imperial Camshaft.
This "fix" is common in Pro-Stock when Timken Bearings are fitted to the Cam Journals.
There is NO COST increase to specify a "Timken" cam bearing size, thus another reason for MY VOTE for an aftermarket block.
HIGH valve spring pressures, if required, will cause a "babbitt" cam bearing failure with loss of Oil Pressure.
You could call Chris at CBM motors as he states "over forty" cases of the CP block with success.
