SBC TPI 0411 24X conversioin

[Mikey G]

Hello All,I built a 500hp 383 SBC and put it in a project. in the beginning, it was carburated for simplicity so I could have concentrated on debugging the car. Later I cleaned up the TPI set-up, modified it, replaced all the sensors (map,iac,tps & iac), and installed it. I knew there would be a drop in hp but loved the look of the TPI. I went with the 7730 SD set-up. With the exception of the idle quality, the balance of the tune is pretty good. I have yet to get the cold start-up and idle from being quite rich. I have checked for vacuum leaks. I changed the rotor, cap, wires and plugs. Changed the injectors, had them flow checked and matched. Did a compression and leakdown test. I believe I'm asking too much from the 7730 SD set-up with this cam 242/248 @.050". I have been thinking of doing the 0411 24x conversion. Has anyone had good success with a similar application?Mikey G
