ok, so ill do my best to outline everything here and explain the reason for my questions. i have done quite a bit of searching and looking on here and all over online and am still slightly unclear about a few things... so heres my story. i will be swapping the 5.3 out of my 2001 gmc 1500 and dropping in a LS1 out of a 99 camaro ss. now before you start telling me to buy an lq9 instead let me point out my 5.3 has 205,000 HARD miles on it and is tired, i live in bfe and had zero luck finding a decent lq9 or lq4 for that matter, and the price on the LS1 is right, very right it has low miles and its close to me. i do not plan on going crazy with it i drive this truck on a daily basis i do not race it. i am right now only figuring on a small cam probably headers and of course having the ecm retuned for the engine and mods. so heres where my questions begin... i have read a couple places that with the truck accessories there is a fitment issue with the front of the water pump? also if i were to use the car intake manifold then id really have accessory fitment issues?and need to swap the injectors(no need to go into performance talk ive definitely covered that in my search) i guess to say the least my main concern is what all additional i will need to purchase to make the swap. i have all of my truck parts obviously and the LS1 is a complete long block with the intake still on. i just want to have every odd and end i may need come the day i make this happen. Any help is appreciated and Thanks in advance!
