Reviving some old W2's

My Econo W-2's flowed 280'ish when done in '93. Flow doesn't always translate into drivabilty and HP but is a good benchmark. They can go 300 cfm with some serious work.

My engine is a .020 over, 3.79 stroke deal with 13 1/2 compression and a 750 methanol carb on a ported M1 intake. Did 575HP with a Isky cam of early 90's vintage. I'm hoping that my new cam and a more modern carb will get me around 625HP... we'll see.
