Coyote Jack needs to jump in & post some pictures of his blown Demon.
 
I need to make a decision about my block.

Do i make less power and use a stock block or save another 5 grand for the aluminum Rittler block...

How much power are you guys making and what block are you using?

Thank you.

I have a stock block and the block held up to 700 hp but unfortunately the stock balancer did not. I now am running the pulleys to a more conservative hp rating. The difference between 11 lbs of boost and 6 lbs of boost.

Thanks Jack.

I think im gona just use a crank hub, i dont drive the car much anyway.

Real quick.

Are you using stock main caps?
For 600 i can get splayed billet caps add a hundo more for the girdle.

The machine cost is not an issue as my machinist owes me some favors....
 
I have stock caps and crank. I went with Eagle H-beam rods and trw forged pistons. They are on the heavy side but that is good for standing up to the prolonged shock of ignition in the cylinder of a boosted engine.

Ive been in the process of building one for about two years now.

My stack of parts is almost complete and i am just about ready to roll the parts next door to the machine shop.

I have in hand a forged Eagle stroker scrank and H beam rods. I have payed for custom pistions but have yet to decide on the height untill i pick a block.
Edit- i forgot, ofcourse i have a new 6-71 from Dyers and manifold. Also two 660 center squirters that are modified, matched, flowed and powder coated.


My issue is an 8-1 comp 360 (in my case 408) will put out about 300 HP. Add 7 PSI and you only at 450HP.

My current build is already pushing that NA so im not willing to commit all the money untill i can come up with a good blueprint to use.


Would any of you be willing to share your build?

Finding folks who know how to do a Roots build is almost impossible.

Thank you all and if you want i will start a new thread so this one can be just pics?

I don't get the 300 hp rating you are giving your 408. Put a good cam in it and you should easily get 450 hp before boost. I went to Steve Morris Racing to design my cam. It was matched to my entire car including me in it. A little more expensive going that route but I know the real potential of my setup. My comp ratio is 8.2 to 1 static and I am well over 400 hp before boost and depending on the amount of boost I use I can get up to 650 to 700 hp.

Yeah, I don’t get the 300hp at all!?
You should EASILY BE PUSHING 4-450hp and a solid 600 with a with 7 psi

That's a great testament to the stock Mopar bottom ends.

I’ll be using an ‘89 LA Roller block. B&M 162 blower, Trick Flow heads, Solid Roller, Gear Drive. Boost output will be low, so I’ll only be at around 500 horse. Later I’ll go with a 671, for around 650 horse.

Let me know if you need a place to store that 162, when you go to the 671
