For the last 10 years, my brother,Alan, has successfully raced his Stealth 598 Step V in the NZBMC series with a 4.3 v6 190 hp mercruiser.
Well, the time has come for Alan to put on the big boy pants, and swim out to the deep end!
He's dumped a 383 chevy crate engine into the engine bay!
He moves from D class, up to B class.
What a beast!
