Generation IV Internal Engine - Got the build sheet for my 427

Got my build sheet yesterday for my new motor. It is a Darton MID sleeved LS1 block with LS7 heads and intake. Even with the baby cam going into it, we expect to make @560 rwhp AND @540 rwtq N/A (shooting low :jest: .. this motor is capable of well over 600rwhp N/A as you have all seen from some recent posts. :) ). 11.5:1 compression...

1 month to go and it will be finished! :fluffy:

Looks good. You should have got an Evans pump to go with the Evans coolant that you need for those Darton sleeves.

nice. should make a fun very streetable car

Thanks. That's the idea. :devil: This is going to be daily driven. I'd like to take it out to Sebring soon.

Bravo... I will take a look at the Evans. There's a little time left. :D

Yeah, if it's the MID wet sleeve then the man who designed them recommends Evans coolant and pump. For a block that expensive I wouldn't cut any corners. Good luck.

My friend had problems with false knock on the slp underdrive pulley. Take a look at the march or ati crank balancer. Otherwise it looks like a beautiful combo. I'm sure you'll make lots of power with those heads and intake.

Agreed on the water pump. The LS2 is worse than the LS1 anyway. The evans pump and coolant are the only way to go for the MID.

The only thing about the Evans pump is that it makes you cringe when you have to spend almost $500 for a belt driven pump. That one hurt when I clicked the "confirm order" button :jest:

X2, i would like to know as well.

I would rather buy an LS7 Crate motor than sleeve an LS1 block.

Just my .02

Our Joeseph is growing up so fast... seems like just the other day he was swapping out his first cat-back on the car!

x3 on the cost.

I wanna know how many decades I am going to have to save to get one in my car.LOL!

PMs Sent. The time and attention to detail behind the assembly of this engine is top notch.

There are plenty of sleeved motors running around with no issues. This engine is being built to handle a lot more abuse that it will ever see, so I'm not concerned. :)

Love the new sig Joe. The car is going to be a beast :D .

David

It's meant to be a fun daily driver. Take it to the strip, Sebring, Saturday night hangouts, car shows, and the grocery store. :D

When did Harland Sharp come out with LS7 offset adjustable rocker arms, and how much are those ??????

My engine is getting the first .. or one of the first ... of the new Harland Sharp rockers. Not sure on price. I'll have to ask.

dana 60 huh?

interesting.....

;)

Yeah... talked to a local guy about it. He's getting one and swears by it. I wonder if his has arrived yet. :D
