Nice, did you have to mill the sparkplug bosses for clearance, or shaving weight?

They were milled for clearance. The bosses were originally there as those castings are used for dual plug applications as well. I milled them to eliminate any potential rocker clearance issues.

How was the heat down there yesterday?

How was the heat down there yesterday?

It was pretty humid. I degreed a cam, checked piston to valve clearance and measured for pushrods on a stroker RB in the bed of a truck in the heat. Lots of sweating, lol.

So these heads finally showed up... I couldn’t help doing a mock up of the top end.

Ridiculous but in a really good way.

It looks as if there’s just as much work to do to the top end as the bottom. I still need to fabricate injector rail hold downs.

Wait until you see it on the dyno. That’s gonna be ridiculous, lol.

What kind of horsepower are you anticipating?

I think these compressors are good for about 2,000 at the flywheel. We’ll see how close I can get.

That is absolutely INSANE!!! If you can keep the heads on with those numbers, you are the MAN!!!

whats the torque curve look like ?

It’ll be on C16 fuel so keeping the heads on shouldn’t be an issue. We’ll be lucky to make half that on 93 pump gas.

With those small turbos on that 540 cube Hemi, it should look like this at 1600 ft/lbs or so...

How much do you realistically think that you can put to the rear wheels?

Eventually all of it within the first 660ft...

So you hope to put 2000 plus HP to the pavement for 1/8th mile?!? WOW!!!
