Clamping force in question !
Clamping force in question ! Just sent my LQ9 block and 317 heads to the machine shop. Getting double o-ringed and 1/2" studs installed. My question is how bullet proof is this combo?? A friend of mine has the same block and head work as I described and he's 13.5:1 and spraying 500hp with a plate and fogger system. I have know idea what his cylinder pressures are but they gotta be high. He's never lifted a head or pushed water so I'm feeling pretty confident. I'm going forged 370 with either S88 or F1. So I'm wondering about lifting a head, the PSI will be pushed pretty high. The compressor maps will hold atleast 30psi, so anybody got experiance or input on this setup ???? Thanks in advance..
A properly machined double o-ring set up is good for 1,500 hp+, but this is with aftermarket heads. I don't know how well the stock castings hold up to this with their thinner decks, but I would suspect issues over 1k as a possibility.
Don't get greedy with the tune and you should be ok for some good power.

Ok, I talked to him(Morton Machine)again. Here's what he said; .040 stainless double(one in the head and one in the block) concentric o-ring. And yes the LS motors only have 4 bolts per cylinder. Soon to be 1/2" studs torqued to 100ftlbs and he insists on the .060 copper gasket. Its a centrifical blower pushing 25-30psi and deck thickness is unknown, factory iron block with factory aluminum heads. It will be making roughly 800-900 RWHP with this combo.
So with this being the facts or what I know as fact. Whatcha thinkin ??
