1000HP SBC in the Making

[Fatman]

Just a couple thoughts that may be worth considering:

Will a 1000hp all motor combination be a good motor to then try add 400hp of nitrous?

Would he be better off building a motor, say 800 or so hp, with components and a combination that lean more towards nitrous use, and then spraying it more?

heads tuned up by ( Larry or Darrin etc.)

Who's Darrin??

[Transman]

Morgan, from R-M. I know a pal in Kansas is pretty pleased with his SB2.2 head from Arlington.

[EngineTech1]

Darin Morgan runs Reher Morrisons cylinder head department.

Used to!

Just saw a post on another site by Chad Speier that Darin resigned on Monday from R-M to move out to Denver and work with Dave Capriotti on Cup heads.....

Watch out NASCAR guys, here he comes!

I stand corrected.

For a 1000 HP SBC on a bunch of N2O I wouldn't be using an SB2.2 and a single carb. If you do use an SB2.2 head, the Weld Tech heads you are looking at are not the tool for the job.

You might talk to some folks that have been there and done that.

I would instead talk to Gene Fulton...and ask about a Combo from Milton Decker... Gene has been there, done that...and has the tee shirt.

As you get a little further into this, I can probably be of a little help to you with some areas of this project.

We are currently in the process of developing a nitrous specific piston for a SB Bore engine without adding a ton of extra weight to it. First versions of this should be completed in the next couple or three weeks.


Ed

Ed, I'm very interested in hear more info, of the RD on your piston. Any lil advantage I can get, is a BIG HELP!!!
As far as help from your friends, Age/Time has taught me, except ALL & Any help you can get, But Never bug/annoy anybody!!!

I agree. I've worked with a few guys running those engines in drag cars and generally if you have the right cylinder head/camshaft combo horsepower is a non-issue. Even the 18-degree SBC stuff will make near 800 without much effort. I believe a cast intake will get you near 875 or so with the 2.2 heads. Don't forget they were designed to be a single 4-bbl head to begin with! Next up would be a sheet metal intake ala Hogan's, CFE, TRE, Hughes, etc. If you plan on running an automatic torque converter selection is critical with an engine like that. With a 2.2 I always recommend waiting until you have solid dyno information before getting a converter built, even more so than any other SBC combo.

The Convert will most likely be around a 7000 stall, but like you've said, I would have to see the dyno sheet first.

They are limited to displacement and bore sizes, that only leaves a VERY small range of stroke length. If they were suddenly allowed to build 400cid engines don't think they wouldn't jump on that longer stroke.
Giving up displacement when you don't have to is not smart. The more stroke he puts in that thing the easier it will be to reach his power goals.

I Agree

I personally don't think those heads will get it done. Thats a pretty small port and it doesn't flow very much. The GP heads are good stuff I just don't think that particular version is even close. Definitely not designed for the application you have in mind. I would think you would need closer to a 300cc or bigger SB2 port with a 2.18 valve that flowed more like 420+ cfm.
I don't know about anyone else but that's the way I'd be leaning on the heads. I also agree that you are going to need a sheet metal manifold and dual carbs to get to that 1000 hp NA goal. I did heads for a SBF 468 that was a very nice dry sump engine, the heads were Victor Glidden's over 420cfm, and it had a sheet metal intake with a single dominator, it made 980hp. This was built at Kuntz and Company, and with another dominator it would have cracked the 1000 mark I believe.
Build it big!

The intake valve is 2.18, and they've been hand finished to flow 410 @ .700, and I thought a should keep the port size as small as possible, to keep the the velocity high.

1. Start with a new set of castings and have the head designed for what you are doing.

2. Keep an eye on piston design with that much dope...

3. 1khp is not nearly as easy to do as some may say....this is going to be a very costly operation...probably double of what it would cost to do the same with a conventional head BBC...plus the BBC would like the dope even more! If you are not class racing...you are crazy for spending this kind of money!

4. Do you have any idea how hard this thing is going to be on valvetrain?

Dennis

Dennis, you're right!!! It is a lil Crazy to spend the money on something that you can't sale, and get my money back!!!
BUT!!! in our sport of racing, That's just the way it is. But if I hit my goal, it'll be worth while to me, and I still would have spent less money then those guys with there Mountain Motors!!!

Even our 468 with a dry sump and naiser sheet metal manifold with a good dominator was still 20hp off and I don't think he's going to build it that big. I will say though that the more displacement he can get in that block the better chance he will have of getting to his 1000 hp goal.

A tad smaller.
A 454 is what I had in mind.

[Browns DMX Racing]

No offense, but you should build a 1000hp NA 365cid small block sometime and then tell me about how easy it is. If it were easy everyone would be doing it. That's like a badass pro stock truck engine and not too many people were building those and running up front.
I like the idea of a 4.2 bore but it'd be a LOT easier with a 4.125 stroke crank if you can fit it in there. 457cid as opposed to a 365... There would be no comparison.

I think the Cup guys can & do make alot of power, but they have alot of R.D. behind them. For me, I would have rely on extra Cubes to reach my goal. My thinking is, the cup guys can make 2.25hp per cu.in., I would need the extra cubes to reach my goal. 2.25 x 454 = 1021
But being new at this, and not having all the R.D. to help, it'll be a tuff road ahead!!!

[Browns DMX Racing]

This has been just my opinion but after I have been seeing 860hp with 1 830cfm carb, single cast intake, 12to1 comp, 55mm cam with .875 lifter, 4.184 x 3.26 stroke make that kind of power and turn 9500 rpm I think that
2 dominators
fab sheetmetal intake
heads tuned up by ( Larry or Darrin etc.)
60mm cam with full roller package
13to14 to1 comp
and still turn it no more than 9600 - 9800 rpm

Just my 2cents, but I think it can be done.

SO!!!!
Larry or Darrin are the fellows to talk to about Touch-Up work???

[Browns DMX Racing]

WOW!!!!!!
Thanks!!!! All You Guys!!!!!!
I see, I have a little more planning to do. (that's probably a under statement)
But the Quest is still on!!! The completion time is just pushed back!!!

If you have more words of wisdow, Speak Them!!! My ears are open!!!

When Pro Stock truck finished up the best 358 CI small blocks were making around 950 HP. They were using the splayed valve head.

The Aussie Pro Stock engines are 400 CI and are making roughly 1050 to 1080 HP now.
The hot setup heads for these engines are the Dart Little Chiefs which need the lifter bores moved in the block to accomadate them, The BAE billet splayed valve and the CFE splayed valve head.

Taylor Lastor at TRE has built the Aussie Pro Stock record holders engine, So he might be worth a call to see how hard it is to build a 1000 hp small block as I would imagine that it could be done but would take a little bit of R and D.

Sonnys build some big inch small blocks which are stout as well.

[Competition Engines]

I think you'll need a little more cylinder head, in the 450 cfm range, and enough port volume to support this size engine. You should worry about too much port velocity instead of not enough with this size engine. The Dart Little Cheif is definitely the way to go for what you're wanting.
