We then offer main studs, 12mm head studs, and the proper head gaskets. Finally, there is some case prep and a few other internal goodies to support and help make the power. It's all parts that have been built, tested, rebuilt, and proven reliable to 1800whp and well past 8000rpm.

On the top end, we have a top end package that includes CnC ported cylinder heads, big valves, big springs, and a solid lifter conversion including cams.

Everything you need to break 215mph 1/2mi and well beyond that.

Contact us if we can assist, I can put you in touch with John Bray.

The 12mm studs need case work ?

You just have to bore/tap the case for the added thickness. Sean (itguy) will be releasing a kit the end of this month (I believe) to do just that. I believe it's on the 1st page of this thread.

The case needs to be drilled and thread inserts installed. You also need to clearance the cylinders, liners (depending on which ones you use), and heads for the larger studs. That said, they're proven to over 1500wtq at this point without issue...

That is correct. We use our high strength head gaskets. They're slightly thicker than stock and come sized for the 102mm bores. Compression ratio is 9.0:1, even on Anthony's car I believe.

That's great! Thank you for taking the time to comment on this thread. EvoMS is the leader in making HP on these platforms and your comments will save guys years of headaches and a lot of $ to do it right the first time. Are these the hellfire gaskets listed on your website? 9.0:1 to exactly where I want to be.

Thanks!

One more question...... I'm going to put for this "general guideline" that the pauter and carrillo OFS rods will be a good replacement up to 1200 hp, I think the stronger carrillo rods are rated at a max of 1600 hp. Do you guys offer a rod for 2000 hp? I believe the Undercover 300M ones fall into that category, but I'm sure you guys offer some too.

'Version 3' is bomb-proof in terms of design, material, and hardware, and has so far been made only in 4.0L geometry. We also have a few different wrist pins we use as well, with the high end being a thick wall, tool steel wrist pin.

I haven't figured that out yet. I have a machine shop in Edmonton that I've used for a long time that I really trust but I'm hoping to find someone in Calgary. I'm going through the struggle in my mind of local vs a proven Mezger builder like EvoMS. If they were in the same country it would be a no brainer, but when you combine the dollar, shipping etc. I'm hoping to stick closer. I'm not sure if western Canada is any better for you than the USA but I'll pass along a few names when I dig a bit more.
