block designation
block designation hey all quick question. what are the diferent names of the ls1 like lets say one of the truck versions is the lq9 right?? well what other designations are there and being that they are all based on the ls1 design i could just drop that block and or engine on lets say my t/a right?? not sure if this is the right forum so sorry if iam in the wrong place.
The engine RPO codes are as follows:
LS1...345c.i. 5.7liter 10.19:1 25534322
LS6...345c.i. 5.7liter 10.46:1 12578104/12562190
LR4...293c.i. 4.8liter 9.47:1
LM4...325c.i 5.3liter 9.49:1
LM7...325c.i 5.3liter 9.49:1 12562201
L59...325c.i. 9.49:1
LQ4...364c.i. 6.0liter 9.41:1 12575147/12575148
LQ9...377c.i. 6.0liter 10.08:1 12499467
Differences being of course Aluminum vs. Iron block and obviously where the accessories are mounted also the truck blocks have some slight internal an external differences but are the same external size as the car blocks.
As far as being able to bolt right in,yes they should but , Im sure you would have to check motor mounts, exhaust, transmission mate up to the block, oil pan, etc.etc. (You do that with any motor swap).
My buddy has a 408 iron block in his TA and if I recall they had to do some minor things for the install but nothing major.
I hope this helps you out, good luck.
