One limitation to keep in mind if you go with throttle body injection is that if your manifold is single plane (mine is effectively single plain due to the one barrel adapters to the throttle bodies) each injector will need to squirt 8 times per engine revolution for good fuel distribution. If you have a dual plane manifold and each injector squirts into a different plane like with the original GM TBI, it should work fine with four squirts per engine cycle and will generally easier to set up. 8 squirts is a lot to fit in even when the max RPM is 4000 RPM!
