hey guys was up gotta question hear , i want to build something for the track and some street use but hear is my problem i wanna know the advantages and the disadvantages in building a 383 chevy with respectable horsepower nothing to turn your nose at and enough torque but hear is my delema i wanna build that 383 but with a weiand blower with 12% underdrive and a 750 single pump carb and a supercharger shoving air into the 750 holly and through the weiand blower from summit and the supercharger from (procharger.com) which cancels out the air filter and the scoop for the blower but may require a new hood with some mods and i all ready know the lack of room under the hood with all the new plumbing but this will hopefully be working this year or next thats if it works well .
just want to know

why stop halfway
Build a 400.

Re: why stop halfway
ya but with a 400 you dont get water jackets for the four center cylinders and i heard they where bad for cracked blocks and you cant get the hp from building a 400 like you can get from a stroker motor . if you wanna stroker 400 what can you stroker it with a 350 and make a 377 no thanks i have better resourses in getting a 350 to make a 383 than trying to find a 400 and make a 406 or a destroker 400 to a 377 sure you get the longer stroke in a 377 but you can get just as long as that in a 383 so why not go with a common block and a common stroker kit plus i bet you can get more hp out of a 383 than you can a 406 30 over 400 or a 377 destroked 400 which involves sleeves .

cu in = hp
Cubic inches equal horsepower. How could you possibly not get more horsepower from a 406 as opposed to a 383. At 1 hp per cu in, you still get an extra 23 hp. I bouht my last 400 core for 150 bucks. For a basic street rod you pay appx 10 bucks per hp. 23 extra hp would be 230 bucks. You do the math.

OK, am I reading this wrong or are you talking about a setup like this:
Procharger-->750 carb-->Weiand blower-->engine.
If I've got this right, then I gotta ask WHY?
You can make way more power than the engine internals, or the block for that matter, can take with just a properly chosen Procharger setup. Why not skip the inefficent Weiand Roots-type setup altogether?
To Bracketeer: I respectfully diagree, cid does not equal hp. Displacement alone will make more torque, but hp is a function of airflow. If you have a hypothetical 350 make 1 hp/ci, that same head, cam, exhaust and intake setup will not make 1hp/ci on a 400. It will probably make the same 350 hp, in the area of 15% more torque, and the hp peak will be at about 15% less RPM than on the 350 (all ballpark numbers).

well i figured i will try something diffrent i just wanna know what kinda horsepower and torque numbers ill be looking at and what the car would handle like i dont see why it wont work sure extra money and extra time and so on but you know what its all ideas and i grabbed that one and figuered ill ask questions .

"Procharger-->750 carb-->Weiand blower-->engine."
:nono: I think I would add a turbo and NOX system too...
I mean, if a supercharger is huffing into a blower, then you'll need something to get you into the RPMs faster, the NOX will cure the 'turbo lag', then the turbo can feed the procharger, which will feed the Weiand blower, which will feed the engine, which will feed the turbo which (theoretically) will become a perpetual motion machine as long as the fuel supply...
That should REALLY be spectacular when it comes apart!!

First I would skip the 400 cooling prolems and thin cylinder walls with a blower and your asking for problems.

why?
i dont understand why you would put 2 separate forced induction systems on 1 engine. i would think it to just be a waste of money.

listen i never said ill do it i said i just wanted to know if it would work if you go back a few posts i said that before just a thought i fully realize it just might be a waste of money fair enough but it was still an idea never said ill do it

The old Detroit Diesels had both a turbo and a super charger on them. In fact, thats were the first blowers came from. Guys were adapting them to car engines. I believe you would have more luck with a turbo/supercharger combination. At least that way, it would be kind of a perpetual motion type thing.
Ie: The blower forces are through the motor turning the turbo faster which feeds the blower more air...
As for the question of "why" I ask "why not" some of the greatest things in the world seemed odd at first. If you can come up with a setup that won't blow itself apart, more power to you...
