Mazworx billet block.
 

I am trying to round up 5 people to see IF Mazworx will make us a billet VQ37VHR block. We need the interest to help sway Mark to make it happen. It's a ton of work on his part. The price will be around 10k for just the block. If you already have sleeves they can transfer over to your new block. I have 3 people so far. We need at least 2 more. It will take time to develop IF we can get him on board to do it.

This is the link to his billet VQ35DE block.

Not going to be able to join in, but what are the differences between the 35 and the 37 blocks? To the best of my knowledge, and I could be completely wrong but aren’t the differences in the rotating assembly and heads? What are the incentives to do a 37 billet block over a 35?

The heads and block are different on the VQ37. It doesn't look like this is going to happen.

how much power can our stock block hold? i believe over 1000 after rebuild?

LOL, It's the tq that kills the stock engine. 650whp or so as long as the tq is keep 550WTQ or below. A built engine reliably, That's a good question. About 850whp is about it. The stock block just sucks. It's a head lifting machine.

:rofl2:

Not for long. Plan on spending $70K+.

Or just do a bottom end build, keep it in the 800whp range and save a hell of a lot of money

I was at 718whp at 17psi and lasted 7k miles. If you drive like I do, it won't last long.

Mine makes that at 15 psi but unfortunately, as you know mine's a stock block. 7k miles. That would be about 5 years for me :rofl2:

IMO a VR38 swap is way more reliable long term and will be almost the same price, and you get the benefit of something that is well known to be reliable to 1300whp with just rods and pistons.

I agree, it will be cheaper in the long run due to not blowing up motors. Do that once and you can damn near recover the extra cost with the VR38 swap. It does depend on how far you go down the rabbit hole. Dry sumping the VR38 to make for easier fitment.

Making that power and never using vs making that power and using it all the time is a huge difference. Open deck or built bottom end with Hg won’t last long period. It’s hasn’t for the 10 plus years the VHR has been out. Now we do have some unicorn build’s amongst us but the negatives still
Outweigh the positive. If you’re so confident start entering 1/2 miles races and run them
At full
Power.

Yeah, it is heart breaking. But we can't change it.

A. More money needs to go into R&D to overcome the junk cast, B. Swap a VR38

Maybe so. I may just turn it down to 18psi which is right at 800whp. One thing is for sure. It will be off the chart under the hood with some new bling.
