Ok I plan on going from ls1 to an lq4, hopefully a 408 and planning on boosting through a d1sc procharger. Are any of the parts interchangeable from the ls1 to the lq4 such as ac compressor or any accessories? Also what heads should I go with on the lq4 block seeing as how I dont want the truck intake?

 

Every thing is interchangeable. Only difference is the bore size and the lq is iron block

 

thanks man, i was just making sure because im in afghanistan and i wanted to know if it was interchangeable before i waste my money fixing the a/c on the ls1 before i end up doing the swap when i come home for good

 

Just need to drill the hole in the mounting boss on the driver's side of the block for the alternator mount. You also need to use your oil pressure switch from the ls1.

 

the oil pressure switch/sensor that sits behind the intake manifold?

 

Yes. Trucks use 3-wire switches, F-Body uses a 1-wire.
