Engine masters apparently allowed 4 valve mod engines into the competition and the two entries claimed 1st and 2nd (Mihovetz/Accufab). Kaase's entry displaced 409ci making it the largest mod ever (according to the mag). Both entries had '00 cobra r type intakes. Makes me want to put a mod engine in my car!
Got a link to the results? Were they using 2003-4 heads with a Ausi Falcon intake?
I thumbed through it at the supermarket so I didn't get all the details but here's a link:

Just noticed BES was running a mod and they got 3rd. I assumed they were running an LS based engine.
