There has been a lot of controversy in NHRA Pro-Stock ever since the V&H 4 valve Billet HD. a few years back..
Matt Smith has been very vocal over the current V&H Teams Motor and there "Slow" supply of parts & spares to other Teams in Pro Stock "especially the quick ones"
NHRA were also very slow "like over half a season" before adding weight to the V&H Bike
Oooh yeah V&H are an NHRA partner ..........ODD that
