Hi all,
I have a 4.3 V6 Vortec with 4bbl carb. I'm looking for a bit more torque and pickup without swapping to a V8.
I'm thinking an edelbrock inlet manifold to replace the gm12550460 manifold I have already.
Also, it has a Delco EST ignition. I'm wondering if the MSD 6M-2L ignition unit could be used - it has some features such as a capacitive discharge, and produces multiple sparks for the first 20 degrees of rotation below 3000 RPM, which should improve performance. I'm not sure if it's compatible with that ignition, though, so am digging around for wiring diagrams. I've got a sneaky suspicion that the ignition module is housed in the dizzy cap on the delco, so possibly couldn't work without swapping out the distributor as part of it.
Would there actually be any significant benefits in performance with these add-ons?
Ultimately, I'd like to go one pitch longer when I next change my aluminium props, possibly going for stainless whilst I'm at it, so I can cruise at a fractionally lower RPM, without sacrificing accelleration onto the plane too too much.
Any thoughts very welcome!
