Did it keep the vacuum pump? Hope so.. can't wait to get my ls-lt water pump adapters in and offer the rest up for sale ..only 4 though.
Can't find anything linking a lt1 to a ls fead setup but it looks like it would or could clear a vacuum pump.

No, the vacuum pump was not retained as it won't physically fit in most LS swap applications. The pump is only used in truck applications to augment the vacuum signal when the engine is operating in cylinder deactivation mode, so if will not be needed by someone that is not interested in utilizing that function in their swap.

Good to now .. wonder where they are drilling and taping the hole for vacuum. Be interesting to see the holley setup.
