New 416" street/track motor just fired up! (pics, vids, specs)
Ok finally got the 416 motor running yesterday... Yessssss!
I bought the block on April 17, 2010. So about a year for this motor project. But really more than just a motor project....
Motor's is really nice. Revs pretty quick for a 4" stroke too. The idle and sound of Comp 274S mechanical cam seems like a good compromise for street and track car I was looking for. I'll report more later when we take it on the first drive. Troy Bray that used to be with Westoaks MP made this deal happen. He guided the whole motor built, ported the heads, has great fabrication skills.
Now to get ready for Spring Fling Speed Festival on April 14, 2011. It our track day out at the Willow Springs big track (loooong straights)
