LQ4 replacement for my broken bottom end LS1!!!! Any tought or suggestions????
So i have a 2000 camaro ss and last month i totalled my bottom end with a broken piston damaging the block....cracking the.block!!!
So today i came across an LQ4 engine but im not sure if its a good thing to do!!!????
Any insights or suggestions would be nice before i buy the block tomorrow......also will i be able to use my old assecories and headers??? Thanks for ur help in advance :-)

Did you have anything done to your old motor? Thaw lq4 has a fished piston which will lower your compression a little if your just swapping long block for long block. So you might lose a little, but probably not that noticable.
If you wanted to throw some money at it you could mill some of the heads, put flat top pistons in and do a cam swap before you drop it in and then you'll have more power than before

I talked to one of my friends he said to leave the lq4 heads on the block because they are bettrer flowing heads, so im confused should i mill the LQ4 and slap them on or should i mill my ls1 heads and slap those on???? Also right now im on.a budget limit so as soon as i buy the block ill have an extra $400 to spend wat should i do to make this a better and makre stronger block then the ls1

While you've got the heads off and gonna have to run through install height anyway I'd put Pac springs on it now. I wouldn't mill too much off the 317 till you decide for sure if you are wanting to go FI or not...

.030 milled 317s with thinner gaskets will still barely get you to stock LS1 compression.
they do flow a tad better than the LS1 head but if you are pulling heads and milling i'd prefer to raise compression and get the torque bump from using the LS1 head vs the slight flow increase.
