just wondering if anyone has had their block o-ringed?
my builder wants to o-ring the block as insurance for running high boost.
I understand the way it worksand did some research.... looks like almost all high hp race cars do it.
just looking for any info from people that have done it.

Very hard to o ring a 7m and have it last as the space between cylinders is so small. And if it fails the block is toast.

Better off just sticking to a mhg. A very low ra on the block and head and a very clean and well prepped and assembled engine with a mhg and arp would be plenty
