Going to start buying parts here and there for my new build, 347 stroker. It will be with a boss block or Dart, still in the air on that. Current setup is Trick Flow top end kit(heads, stage 1 cam, track heat upper/lower intake, 1.7 rockers). Car also has a S trim with power pipe.
Couple qusetions:
1. Currently running 38 lb injectors, what size will work best with new setup? 42, 55 or 60's?

2. Who makes the best bang for the $ on fuel rails?

3. Porting heads, I hear there is a guy by the name of Gill in Riverview that does good work, any other suggestions?

4. Currently have 70 throttle body, will I need to up that?

Also, has anybody had any experience with the G-Force kit for the tranny?
