I have about 7-8k to play with and I'm thinking I want to do a motor swap, but I know all this shit is hella expensive but I was thinking of geting a lq9 408 long block from texasspeed and the l92 cam and head conversion from pcm. Wha do y'all think will this even work? Or maybe an lsx 376 like the other members on here, idk tell me what y'all think.

I'm headed to houston on Friday for a retune and I'm going to add pcms 4 in. Intake 42lb. Injectors and 150 nitrous and see if that's any better, but I want to start lookin for a replacement motor

So do you think a lq9 408 will work in our trucks? Isent the wiring different from the ls2? And would the Pcm4less l92 convesion work?
cam, crank, knock, and oil pressure sensors are all different locations I think, but you can make it work. why not pull and build yours to a 402 using your stock block?

I was thinking of selling it to get some extra flow since I don't plan to use the stock heads or anything And I haven't heard of any very good ls builders were I'm from with machine work parts and labor I figured lq9 would be cheaper hold more power and a few extra cubes.

Forge the bottom end and see where you are at after that with $ (especially since you are throw nitrous at it). My 402 build was around $11k (minus headers) and I re-used the block. Would hate to throw a H/C combo on it and spin a bearing.

Or invest in the Moroso pan and put a H/C combo on it, that should help prevent any blow-ups.

For that money, with the built trans and converter you have, I would supercharge it, and run mid 11's all day long without the nitrous.
