Supercharged Stroker
I was wondering if it is possible to supercharge a 383 stroker and what if any special mods would be requried as oppsosed to S/C just a standard 351W. what HP/Torq would it be expected to put out and what would the longevity be? If anyone has done this what kinds of parts did they use? Just looking for some info maybe for future project

By all means, yes! But if the 351 is in good running conditions, why not go with that. You'll need to do some fuel system upgrades on a boosted application and if this is an automatic, the transmission will live longer with a big cooler and better torque converter.
How much are you looking to spend and what kind of driving will you be doing with it? What power level are you after?

you think i would be streetable with low boost if i build somthing like this i would want to be able to drive it to more than just a race or out muddin' but i thought it would be pretty cool to put 500+ HP in a truck what supercharger style would be the best? i was thinking a twin screw cuz i would want all that power at the low rpms. but the only twinscrew i can find is around 4000+

Don't look too hard for a positive displacement blower for a windsor truck; they're simply underdeveloped. You'd be better off going with a Vortech. An SQ will have lower discharged temps and support more power than the positive displacement units. A GEN 1 L owner took an SQ well into the 10's and he drove his truck everywhere.
I'd suggest going with some type of charge cooler for a street application running pump gas. I went with an IC'er from 99+ Powerstroke and it does an excellent job of cooling the charge temps; @ 14 psi the ACT's go as low as 100 degrees right at the shift. For an automatic, adding a strong torque converter with a higher stall will definately compliment a centrifugal and allow the transmission to live longer since the converter is the weakest link.

But with the vortec doesnt it act more like a turbo with boost coming on in the mid to high rpm's I would trying to keep and build off of the low end torque that these engines would put out. thats why i would this that the twin screw would have been the better choice over the vortec S/C unless you can get a nice kit that would be able to boost at low RPM's. Another question is when would the S/C's start boosting RPM wise?

In a sense they do, the main difference is that they're belt driven. The boost level and onset is determined by the pulley combo, and I see as much as 3 psi at 3/4 throttle on my 351 combo. I don't know of any 5.8 PD blower kits available that could be modified to work with that motor, unless it is was a used F-150/Lightning kit...I haven't checked though.

how much boost do your truck put out and at what RPM? I i would like a semi-DD motor build i dont drive very much so i would like to go a little more agressive then normal. thats why i was leaning towards the 383 being the more streetable stroker. But i also have been bitten by the boost bug so i would like a low boost S/C.......for now

I can punch mine from a 35mph roll and immediately see 8psi. The only bolt-on and go kit you'll find is from Vortech. There are some mounting templates floating around (from the GEN 1 L crowd) for NOVI 2000 and Pro Charger compressors, if you want to piece your own system together. At one time, Kenne Bell made a kit for the windsor trucks. At the time, those kits were more expensive than some of the centrifugal kits, and many of those kits can/would outperform the a KB. The KB compressor was good, but alot of the supporting parts (or lack thereof) limited its potential.
I can drive my truck in the city or take it on a road trip and it'll run just fine. There are quite a few GEN 1 L owners running just about every boosted combo you can think of (from stock to a stroke/bored 412) and most all of them can be driven on the street.

so on the subject of s/c strokers, this is a maybe on a future build by the way, could a person stroke out a 460 to say 515 or no more than 540 and still superchage it with out shooting a piston through the hood or blowing up the block? This is going to be a multi year progect of a hopfully 900+rwhp 70's supercab street truck. I want to be able to pull up to a hoped up ricer and blow his doors off then go blow away a mustang after that

i wouldnt see why you couldnt supercharge a stroker because your really not adding any compression just adding more volume to the charge of air/fuel. If you were to run low boost you should be fine but you will have to do fuel system modifications to compinsate for the added forced air. As for my question vortec sells there kits for around $3000 are there any other kits around for a little less $$$ or is this the best bang for the buck? What kind of boost can you get out of those system? whats the range for that application?

I believe the only kit available, that is a bolt-on and go type kit, is a Vortech. The SQ trim compressor is good for 20psi at roughly 53,000 RPM (impeller speed); this will be plenty for a stroked street/strip truck.
