Is it possible?
Is it possible? A long time ago when I was building a 351 M for my lifted ford I set a goal of eventually building a motor with 1000 hp. I had to make low end power so I couldn't go radical. Well I got thinking I am planning on building a 408 this winter. Is it possible to make 1000 hp from what once was a 6.0? A simple 408 is supposed to yield around 550-600 at the crank. If I go with high end rotating parts, a big cam, some high flowing heads, and drop shot of juice on it will I make 1000 hp? If I could make 750 on motor alone I would put a 250 shot of nitrous to make up the difference. If this is possible what heads would I need? Also a general idea on cost.
Something that I would love to build but I don't know if it is possible and I don't want to spend really crazy amounts of money. If it would be any more than 10 grand I think I would go with my original plan of a fairly simple 408.
Let me know what you think.

1k HP is not an easy task. If it's all NA thats going to be a MAX effort motor with a giant cam and excellent heads. Springs will need to be checked often with a huge cam and will not be street friendly. Think LOTS of compression and race gas for that. Best route for a NA setup is a good amount more cubes.
FI is a better route to go with that CI and power goal. Thats not cheap at all with a forged motor with higher end parts and then all the FI stuff you would need. Turbo or S/C would run over 10k but be more friendly for the streets but still 1K is a mountain.
I think it would be better for you to set a 1/4 time goal and work for that then 1k HP.

I know it will cost but I won't worry about that goal right now if it is going to be rediculous. The truck is almost never driven and if I build the 1000 hp motor it will be a track/ occational weekend toy for good.
it will cost you more than $10k to build a reliable 1000 hp motor, regardless of combo.
i'd build a simple 408 and spray it, you could easily be close to 800hp or so with a 200 shot. keep in mind that a fuel system big enough to support a 250+ shot will most likely cost you a grand at least, especially seeing that you're starting from scratch.

I can get two high performance pumps, two fuel cells, and the lines for less than a grand. One for the motor and one for the nitrous. Cells are only 100 or so and pumps are $300 or so each. Anyhow sounds like maybe I will build the 1000 hp next time when the kids get older!

Talked to Texas speed and they said it would be nearly imposible to make th 1000 hp mark. He said if I stepped up to a 427 lsx block it would be a bit easier. Looks like I will stick with a rather simple 408.
"simple" 408s can make some power. however, if i was starting from scratch and looking at machine work and new pistons/rods i would really look into a short stroke/big bore 6 liter based engine. maybe an offset ground crank and 4.03 bore. all bore 383 motor with some compression would scream and make power everywhere.
Not starting from scratch. I have a 6.0 in my truck right now. This will be the base for my motor. Therefore the 408 is what I am going to build. Like I said maybe when that motor gets old I will make a 427 or bigger and shoot for the 1000 hp mark.
yeah thats going to be way to hard. and 1000hp reliable car is going to cost atleast 20-30k. everything will have to be redone if done correctly. i would go with top dollar heads, big cam, and a 300shot.
