Designs for building a 700ish HP 383 stroker

I'm looking into building a 383 stroker soon, I already have a 350 bored 30 over, might use that or else summit sells a 383 block for $729.99, I want this motor to snap and am looking for alot of torque as well. Any opinions on compression ratios, heads block, crank... basically a good blue print on everything haha... I have built up a few 350s before so I'm not new to the process but I haven't built a 383 yet... I am not gonna cut corners on this project as that has bit me in the *** to many times...

you can't run 700hp out of a factory block, or atleast long enough to win any race. And at the 700hp level you're lookin at a few rebuilds each season.

I'm aware of that and I am planning on doing the modifications to allow for that much power, i am looking for a simple blue print from anyone who has done it before.

There is no such thing as a general "simple blueprint", there are the normal things that have to be done on a very high performance build but I dont think you got the gist of what ap72 was stating.

A stock production block won't last very long at 700hp, you will need an aftermarket block and the best forged reciprocating assembly you can buy. The cup cars run about 800 hp and they cost moooocho $$$$$$$$$$$$ because EVERTHING is aftermarket.

yes, i understand that there is a lot of work involved but I am friends with really good machinists who will do it for me for no charge... and i no there is a lot of money involved, I am willing to pay big bucks to build this motor, I'm not gonna be beating on it constantly, i no there is no simple blue print as well im asking as for the lower end and heads and cams give me something that has worked for you, to start with...

Running 8's in what and where at?

If they are running in a production car with an OEM 350 block they are NOT running 8's, unless you're talking the 1/8 mile.

And NO amount of machine work can make an OEM block a true race block.

When it comes to questions like this I always to go my default answer: Supercharge it.

Or get a 454 and build a 496.

first, high 8s at Maple Grove Raceway, Mohnton Pennsylvania is where I watch him race at and its in a trans am funny car, NOT RUNNING ON ALCOHOL OR ANYTHING LIKE THAT, 15:1 compression ratio, no nitrous or supercharger... and yes its in the quarter mile, and it looks like oem blocks are racing all over the place.

Also I was considering super chargin but would rather just go with a big compression ratio

If you think someone is running a 15:1 funny car into the 8's NA on gas on an OEM block **************.

I could believe most of that, the biggest thing is 15:1 not on "alcohol or anything like that."
