Billet VQ37HR block.

Idk 5.0 + a whipple dont sound to bad right now. jkjk Ive had my z 5yrs and love it. Ive been saving for years and been on this forum for as long as ive had the car. Cant decide on a very well rounded street/occasional track car or just all out drag roll racing monster either way I hope yall saved some room in that rabbit hole.

Come on Down and waller in it with us.

I think we are at the point of a solution. I have talked to several folks. We shall see. This is my research phase of my next motor build. I want to have everything at the machine shop in 1 1/2 yrs. The billet block sure would help move things along and we would get to skip the step of finding out when the stock block tanks.

By the way. One car already has what I think the solution will be. He has been on the sidelines due to a broken input shaft and then a freaking car wreck with an 18 wheeler. MA-Motorsports built his car.

I'm sure this will be kept top secret.

If someone comes out later and be like we O.Ring the heads and blocked to create a better seal I will

Noop, the block was sleeved. I forgot the name of the sleeves though. He also has a Bryant racing crank. It is a 4.0 liter. They were
not Darton MID sleeves I don't think. It started with an L, I think.... Not sure if they left any protrusion either for better clamping force
and fire ring seal. What headgaskets, I don't know either.

Spooler

The same machine shop that built my engine did his. They are no joke. Take a while but who cares...

Mr.Squeeze

I really hope it works and it just not another failure on a long list of VQ's dating back to 350'z. I have seen so many fail or make well north of 800whp and disappear. One thing they all have in common head gasket/ pushing coolant.

Already been done

We can't leave out SOHO. They have 2 somethings in the works. Guess we will find out when they know for sure.

Its probably a LA Sleeves liner, which I was just telling Seb that is going to be my last effort on the cast block. The last thing I can think of trying is to get rid of the aluminum at the top of the liner, which forms the deck surface. Just bore out the stock liners and put in some dry sleeves that go all the way to the top of the deck. If that doesnt fix it, I am done with that block!

This has been done though, I dont recall by who, or when, or if its being pushed very hard or not.

Even with that, I will still want to perform the other things we worked out to increase the rigidity of the block. Because high power VQ have also been split right down the center of the V before, and no cylinder liner is going to address that.

That's it. LA dry sleeves. I would rather just fix it right the first time. We need 3 more people.

Yeah I really think the solution is gonna be the "hoops" not just wire "fire rings". The way they are going to press the gasket into the boss almost makes it impossible to push coolant.

Try it and let’s us know. That statement is just paper weight
