Hi guys, im looking to put a 454 bbc in my 1971 c10. I am trying to figure out what i can do to get 900+ hp from a 454. I dont have a lot of extra money so this is going to be a over time build. and I cant buy a crate for 5-25k. so i am trying to build a beast that I can beat anything out there, over time. this is going to be my first build so i want it to be done right. it has to be able to run on pump gas. i figured the best way to do this is to throuw a supercharger on there but thats about all i can figure and even then i believe that would get me to 700 I am really trying to stay away from NOS. please give me some info guys thanks for your time

It was all good until you said pump gas. Supercharged w/pump gas capability and 900hp isn't going to happen with 454 cubic inches and probably isn't even going to happen with 570+ cubic inches. Pump gas will only get you so far, after that its go big or go home.

Have you ever driven a car with that much power?
Most of the braggarts out there on the street barely have 1/3rd that under the hood.
Like eric said the "pump gas" is what killed it, you need to build the engine based on what fuels are redily available for it in your area. If 1 sonoco station sells 112 than you cant build an engine that runs 112 because if that station ever goes out or changes fuels you have a 2 ton paperweight.


Another thing to consider is longevity, yes there are engines out there making huge HP numbers but how long do they last?
Parts break and when you push them to the extreme they tend to break a lot of other things when they go.
You said you dont have a ton of money to throw at this project which is fine but I assume that means you can't afford to tear it down and rebuild it every year.

One question is what do you have right now as a starting point if anything?
That will determine what we can suggest to make this street beast happen.

pretty much just looking to get a 900 horses from a bbc with pump 92 gas. I know its possible. I just dont know enough about it to figure it out. this isnt going to be a daily driver or anything. maybe just to cruise to the fairgrounds every now and then. and to be able to like i said beat anything driving past. I have a 2005 dodge ram which is a daily driver for me. so get back to me. this truck is going to have everything ripped off and replaced. its gonna be sitting in my garage till i feel like taking a cruise. I have a good enough job that i can replace parts but im not rreally looking to put that kinda cash into all at once. plus I really want to build it from the pan to the scoop.

What type of supercharger? Centrifugal, Roots, or a Turbo? Something about 630+ cubes is going to be the starting point.

[Chevy2311]

Well I was wanting to get a root supercharger.

[ericnova72]

The only way you are going to get anywhere near the 900 hp level on pump gas is with lots of cubic inches and an intercooler, which pretty much eliminates the Roots blower. Why the Hang-up for pump gas if this is just a part-time toy? Because it is just making it 10 times harder to reach your goal.

ROTFLMAO

[Chevy2311]

Haha cause I know nothing other than pump gas or anything about it and cause I thought pump was the only legal fuel for roads in Texas if there is another way to get 900+ horses with a root supercharger without Nos

[Blazin72]

You better start thinking bigger than a 454. A 632 would be a better starting point....

[techinspector1]

Yeah, and give some thought to the 5000 bucks it's gonna cost you for a differential and rear suspension. Why the fixation on the "900" figure?

X2. If the OP did end up with big HP and didn't spend the money on getting the power to the ground,It's just gonna blow the tire's off and some hot rod turbo Honda will give ya a spanking at the track.

You might try bolting on chuck norris.

900hp on a 454 on pump gas is not that hard, but it is EXPENSIVE. If your original post has budget anywhere in it, forget it.

BTW TI is right on the rear end setup, but he didn't include the new frame, cage, trans, front suspension, etc.

For that $20,000 that the engines costs (If you get it perfect the first time and do all the work yourself) you can can expect to put just as much into the truck itself.

What do you reccomend for a 900 HP 454 build with roots supercharger to get 900 HP without detonation?

I've seen examples of centerfugal running intercoolers but roots on pump gas? Maybe if you run E85 pump gas.
