O.N.

Anyone know what the limit is for boosted applications on the RHS427 block.

And what are people running?
what psi have people blown them up at?

Any other issues with the block you are aware of?


I am planning on building a large boost motor to make about 1000HP at the wheels.

1000 HP wont be near a issue on those blocks.

A lot of good info in this thread

That does not look good, even if it will hold my 1000HP without any issues i wont be risking it unless it's proven to be fixed and better.

Looks like i'll search for something else, any recommendations?

I wouldnt run one after reading that thread on YB

GMPP LSX gets my vote

The RHS would be fine for 1000WHP.

I personally would run a Dart LS Next Aluminum, ERL Block, or a CPP LSX. A RED Sleeved LS Next would be bullet proof for less than a Billet Block.
