With the LQ4/LQ9 you'll need to change the intake (although IIRC some have said it'll fit under a hood with a cowl scoop. The oil pan hangs LOW so you'll want to be safe and get an F-body pan. The front accessories are MEH and some have cobbled it to work and others just saw screw it and went with a Quick bracket setup, F-body Set up or the Corvette setup. The water pump is another area where some just reroute the hoses to make it work and some just get a new one altogether. Honestly np matter what you do you'll be spending money on the car for the swap just depends how much you want to do. Again with the LQ4/Q9 do you want to run a 4l60 or a 4L80 transmission? you'll need to think of what to do for a crossmember with the 4L80e, I bought mine i"ll post up some pics of it when I get home. I would honestly say to try and find an Lq4/Q9 and bite the bullet with some of the added cost. I went with an LQ4 bottom end, muscle car oil pan, LS3 heads and Intake and a custom cam. For my accessories I found some on Ebay and bought the whole thing for around $250 shipped. Deals are out there to be had you just have to look. Look on LS1tech, Corvette Forums. GTO forums you name it if you need a part scour the internet because things are always cheaper on forums where everyone is modding and selling their stock stuff CHEAP.
