2bbl to 4bbl what kind of power increase

We had a Dart years ago with a stock 120,000 mile 318 that ran 18.8.
We put a performer intake on it, a 600 holly and a set of cheap headers and it ran a 16.4 the next weekend with limited one wheel traction and 2.42 gears.
Even with crappy performance gearing, it still really woke it up!

You are not adding headers like we did, but you will still feel it! :cheers:
