Another "Is Fuel Injection a Worthwhile Upgrade?" Question

That's why I'm watching. I have a new QF750 DP annular carb I bought years ago for this motor, and an Edelbrock RPM manifold. I also bought an E-curve distributer 10 years ago. I'm getting old, and now it's time to put this motor together. I'm looking to put this together with the Trick Flow 190's with a solid roller cam, spec's not determined yet. I have a set of coated TTI's step headers for her. She's going in a '70 Swinger 340. I have all the number's matching motor set aside, with the build sheet. My 727 is rebuilt with a 2800 converter. I have the original 8 3/4 with 3.23 open, but I have another A body 742 rear I'm going to put 3.55 gears, and maybe an Auburn diff. I've been lurking for a while, but now retirment says BUILD it.
