Eagle has got big stroker cranks for 360 / 5.9!

As for the longer than 4.00” cranks…… there was a 440” SB build racing in FAST several years ago, that I believe was the quickest SB car in the series for a while.
It was a red Duster that ran J heads i ported along with a SR cam I supplied.
It was in the low 11’s…….back when that was pretty good for one of those.

I think the car ended up sold and being shipped to somewhere in Europe…….Sweden maybe?
