LS7 Grand Sport

Team Owner
The LS7 (which is based on the LS series small block) is a GEN IV small block. The current LT (including the LT4) are Gen V. No GM vehicles use the Gen IV small block now. While bore/stoke block are the same, heads, intake manifold are different, plus direct injection and AFM. GM/Chevy is not going to produce a prior generation small block for just one application. Thus no LS7 (unfortunately).
It's PCV systems hooked to the intake and many lt1 engines suck oil in the filter and intake to some degree we were told to run a half quart low. When heads on those keep Co speed happy with pictures of crap oil covered valves.
To sell the catch can it needs!
Time will tell the lt1 is a dud. Mine was the worse engine ever from GM and I have had a lot of them.
