I don't doubt you because I know it too - specs like that and light weight body will get you there.....it isn't really cheap tho', and I wouldn't even remotely call it street friendly, any street friendly body is just going to slow it down and it will eat up valvesprings. $25 a gallon fuel to run that 15-1 is pretty salty $$$ to just cruise on also.

Doing it with a Factory block is pretty risky , how does your luck run??
An awful lot will get sacrificed if the block gives up.

Outline the vehicle it will go into, its weight, fuel, your performance goals and your budget, then we can start to fill in the blanks.

You also said in your original post that you want a lot of torque as well. That is yet another reason to consider a big block. A 700hp 496 is going to make a lot more torque than a 700hp 383 will.

Yep, and a 632 will do it even easier.
That engine is #1 on my bucket list to do before I cash in....

I've never built one either. I just know that if I were to shoot for that kind of power I'd start with a big block. Probably a 496, maybe bigger.

Techinspector, I like your thinking. Can we put a supercharger on it too?

Anybody remember Hot Rods 632" Crusher Camaro? 750hp at 5800 rpm. 750 lb-ft at 4800 rpm. Cam383aro there's your torque.

here is a calculator I wrote. the preset fields are for an old friends 496. it was a stock 2 bolt production block and not filled. The heads were AFR 345's.

http://www.speedwaybids.com/camshaft_calculator.html

it would RUN on pump gas but not race. In a 3200 lb chevy luv with a large dose of nitrous it went 8.70's. With the same basic combo but with a brodix 2 plus heads and a 730" / 282 @ 050 cam it dyno'ed at 730 HP and eventually went 9.1x's

http://www.streetfire.net/video/Chev...rst_123428.htm


IF you are dead set on a 383 stock block fill it and pray.
14.5 compression, AFR 235 cnc eliminator's (322/231) a cam with 274-277 @ 050 / 630"-650" .... should net the 700 + HP

Is there some place I can petition for a moderator to be removed? "Editing" for personal reasons is perhaps the worst form of censorship.

Build a 421 since you have to buy a dart block anyway, 14 to 1 squeeze, solid roller mid 250's duration at .050 around .650 lift.AFR 220 heads, 800 or better carb will put around 650hp give or take a few.Will pull like a freight train from 3000 up to 7200.106 lobe seperation installed at 102 degrees.

At this power level the cost between big block and small block is less than you'd think, hell a big block build may end up being cheaper. If you want a streetable 700hp I'd start with at least a 502.

OR run a hose to it or blow on it real hard.

and btw it doesnt run 8s everyday. its usually a very low 9 second car

no one ever said it wasn't possible, but that it was next to impossible with a stock block, and you have just proven the point that i tried to make earlier, that he just didn't know everything that his buddy had into his car.

i would personaly recomend a BBC as well, and since you want 700ish hp then you will need to go with a forged rotating assembly so why not go with a 489 or 496, one is .030 and the other is .060 (this will probably be the easiest stroker to make) i've seen 700hp run on a stock gm big block, but it will need clearenceing just like the 383 would, you will need to have a 454 block machined then get a 4.250 crank. it would be far easier to get the hp/tq number you are looking for, and possibly be able to run it on the street. now it would be safer to run a after market block like the DART big M for this but if you were to go that route i wouldn't shoot for the 489/496 i would have the bore cut to 4.500 and run either a 4.250 crank (540) or a 4.500 crank (572) it would cost a little more but the numbers you want to reach would be easy with these CID's and you could do it easily on pump gas you would also be able to match you tq to your hp like 700hp/700tq

With out a power adder, your daily street driving will stink @700hp. Nitrous is nice since you only use it when needed. Driving a high HP car on the track is one thing. Trying to control it on twisting roads when a deer jumps out is a whole nother story. Nitrous lets you keep things sane for getting groceries but still be insane on track day. Plus nitrous can travel to your next car.

IMO Build a strong 450HP 383 with forged internals. Then hit it with the giggle gas. It'll cost 1/2 or less of a NA engine making the same power.
