LS1 to LM7
LS1 to LM7 Alright so I'm swapping out my LS1 to an LM7 since the sleeve had a massive Crack and a chunk of the piston is missing. Now I'm more than positive that everything bolts on and it's a direct swap.
My main concern is the knock sensors, LS6 valley cover, and the tune, how bad will it thrown off by the .4 loss of displacement?
The setup is:
Ported 853 Heads
Ported LS6 intake
Ported LS1 TB
LS6 valley cover
Thunder racing 224 cam
Thunder racing 7.400 pushrods
LS7 lifters
Single Beehive Springs
Powerdyne BD -11A

LS6 valley cover should be just as direct as everything else.
Your tune won't be too far off, the 5.3 will just have to spin a little faster to "catch up" to the airflow demands that the larger ls1 had, so everything is going to seem slightly retarded.
