The vans have a LQ4 which Is a 9.4 or 9.5 compression with dished pistons and 317 heads. The vortex max is a LQ9 with flat top pistons which gets it up to 9.9 CR I think it is. Still has the 317 heads.Is the 6.0 in that van the same block just different heads than what’s in the vortec max?
Both iron block with the same heads just different pistons for different compression ratios.
