i did a search an found nothing interesting so i'll make a post.
at the end of summer i'll have my lil vortec 350 with mildly ported heads, single plane intake and lt4 cam. what i'm wondering is this car we (tbi users) use the stock ecm setup in a supercharged system or am i better off going dfi or holly 950? also can the vortec carb charger be used with our setup.

This is a "universal" supercharging system designed for vehicles equipped with carbureted small block Chevrolet engines. Horsepower gains depend on boost levels, engine efficiency, etc., but can range from 30-75%. Installation time will also vary depending on application, but can range from 4-10 hours. This system has been verified to fit on 1967-1969 Camaro/Firebird (w/cowl hood), 1964-1972 Chevelle and 1955-1957 sedan (BelAir/210 etc.) and 1962-1972 Nova/Chevy II.

Features:

Horsepower gains, depending on boost levels, engine volumetric efficiency and other factors, range from 30% to more than 75%.
Vortech gear driven V-1, S-Trim supercharger for unmatched reliability.
Technologically advanced, high-efficiency impeller and housing design developed in Vortech's supercharger test cell to meet SAE J1723 Standard.
Cast aluminum carburetor enclosure assembly for use with Holley #4150 or Demon 750 MD carburetor. The enclosure pressurizes the float bowls and throttle shafts for seamless response. It features front and rear -8 AN fuel inlet ports as well as multiple locations for pressure/vacuum connections. Linkage arms, splined shaft, and left/right hand spherical rod ends are included for simple throttle connection and adjustment. Carburetor studs are also supplied.

Oil feed and oil drain assemblies deliver the best possible lubrication and cooling for the supercharger, even under sustained boost conditions.
Cast aluminum mounting bracketry with all necessary hardware.
6061-T6 billet aluminum twin mounting plates for rigid supercharger attachment.
3.5" diameter cast aluminum discharge duct assembly utilizes heat resistant silicon sleeves and premium quality stainless steel clamps.

You could probably talk to CrazyHawaiian. He's running an S-trim setup on his. Granted, he has an L98, but if I remember correctly, he's using the stock ecm. The main thing is you are gonna have to use an ignition box that has provisions for timing retard under boost (something like Summit p/n MSD-5462) or switch to an ecm that has provisions for boost. There is a tech article on switching to a Syclone ecm, but I dunno who has done that yet. You are also gonna have to boost referance your fuel system. I'm still working on the ins and outs of boost on TBI too cause my brother and I hope to put his LO3 under a turbo this summer.

i think it would be easily doable, you would need a FMU to control the fuel flow, and then a MSD BTM to retard the timing as the boost goes up.
