Really High HP SBCs ????
Really High HP SBCs ???? Me and my family are planning on picking up a Nova, like a 70-72 body and dropping a SBC in it. We dont really know what size engine we want, We just want it to run in the low 9s. I dont know nothing at all about who builds High HP SBCs or what blocks are the ones to buy or heads or intakes. Im looking to see where I can start finding all this out. Any pointers where I can read about High HP SBCs builds ?

Well, for high hp sbc builds, this is the best forum. Lots of cars in the 9's, the question is, are you looking for street legal? (if so, this'll be tough) Streetable? How much money?
Like, LS1 block, turbo/nitrous, that'd get you into the 9's with the right heads/cam setup. But, that's probably out of your budget (just getting an LS1 to fit would be hard).
What we need is specifics of what you're looking for. Do you want a direct swap? Running a powerglide/hydroglide or a regular th400, t400, etc? I know rob (a friend of mine)'s 1969 camaro ran a 10.20 on it's 3rd run, with a burned clutch. That'll be a 9-second car, on pretty-much full interior (if it's missing anything, I can't see it).

I gotta 69 Nova and I'm plannin on building up a Dart Little M Block stroking it to a 406ci 4.155x3.750
which will leave plenty of meat on the cylinder walls i'm alos planning to slap on an intercooled f-1 procharger boosting around 12-15psi
looking to make around 750rwhp
I think i'll be very much into the 9's of course after the cage, 4 link r/s

Well the plan is to have a car that can drive on the street but it will also see alot of Track Duty. I guess we are trying to get into the world of Legal Drag Racing. We were set on a TH400 but that might change. We were thinking N/A and later down the road spray, a max of 200 shoot. As for displacement. I was thinking of a 383 but dad wants bigger, something in the 400s
For what you want to do a 400-406 is the best option without breaking the bank-use a new dart block with billet splayed mains,lunati or callies crank and rods,some good 23deg heads-something that flows in the 320cfm range-230cc intake port.alot of guys want to build 434's but for them to make good power you need to use an 18deg or 15deg head and then it starts getting expensive.I had a 406 using similar parts as said above,it went 9.70's at 138 in a 3200lb car on street tires n/a.

I've been doing this a long time. I know & have seen a lot of fast SBC guys.
I have not seen very many 9.10-.20 SBC guys N/A. None with 23* heads or under 421"
& no one would even attempt to drive one on the street. I have not seen every SBC guy out there,
so don't go off. It takes a lot of power to get a stock bodied old car into the low 9's.
Get a budget together, total, engine, car, truck, trailer ect. Decide what you can then spend on engine.
Don't forget, it's going to take a lot of dough to make the car even safe,
or work good enough to get a 9 out of it. You don't just drop a badass engine into grandma's old nova
& run a 9.20. Good luck & be smart, do it right, do it once.

Well, this car is pretty-much complete, one of Bob and Rob's projects.
btw - this car has been in the works for around 7 years now. Rob and (his father) bob have all the pics from day-1.
You'll notice the small-block motor under the hood. Rob went out and got his 9-second license, if that tells you anything (yes, this car will be 9-second capable). It's running a 5-speed seq. shift GeForce Transmission, but incase something happens, they do have a powerglide transmission sitting around.
Oh, and although the car is pretty highly modified, it is street legal (with the cats installed and regular tires instead of slick/skinny) and actually somewhat streetable (according to the guy who daily drives an 11-second rsx, lol). So, let's just say that it's quite do-able to build a street 9-second sbc.

As Mr Dragster said, and he knows his stuff guys, take a look at his toys, it needs to be done right, and safe. A 9 second car with only a roll bar is not right or safe.
All that being said, it's a real nice car.
And BTW, why he running cats? It never had me from the factory, so he's not required to run them AFAIK.
Looking closer at the pics, I highly doubt that will bust off a 9. Full weight, no spray. The motor doesn't look like anything exotic.

Well, if you want me to, at the next event the two of us make (and which he brings the camaro, and not his low/mid-11 daily-driver rsx) I'll take a video of some passes, and pm them to you. Ran a 10.24 first day out, with some issues (burned clutch, for example), although that was while I was in Michigan (no pics, no vids from me). Back in NJ permanent (for a while lol - never say never) so I'll be around for his next run in the car.

1st point, anything is possible with money.
2nd point, huge difference between 9.99 & 9.10.
3rd point, maintenance or normal replacement increase dramatically when anything fast hits the street.
4th, where in the hell & why are you running something, you claim is so bad *** with that cheap *** bar.
10 point cage minimum if you expect that pretty body & paint work to last. Not even considering the drivers butt.
There are plenty of 9 second SBC's, especially in mine shaft conditions.
Doing it for LOW 9's & drive on the street without carrying springs, & a tanker truck following is a different story.
Possible, maybe but the guy needs LOW 9's to race a certain class.
I know several guys with 434" & 421" with heavy cars that run low to mid nines,
with all the chassis upgrades & CAGE. They are steetable, with lights & wiring, but not streetable
when you have to buy the fuel & valve train to make it run that fast.
Good luck, have fun & remember nobody knows everything.

434s aren't cheap. I know a guy around here with a 434 at 15:1 with 18* heads. 10.40s on motor, 9.20s on spray. this is in a C4, stock style suspension and 3200 lbs. For strength it has a filled block and it rarely see's street time. Just a perspective for ya.

This motor has run a best of 10.05 in the heat and I am working on the 9 sec slip. It has out of the box 23 deg heads and 434 ci NA on pump gas at 3400 lbs. And I agree to get a small block to run low nines it will take at least an 18 deg head and 400 + cubes or a light car.[IMG]
