Default putting a truck 6.0l into a 1981 z28.

I am about to pull the trigger on a lq4 out of a Chevy HD, assuming the seller and I come to a agreement. I do not want to change my brackets up, it would eat up a lot of money I don't want to spend on brackets. Much rather spend it on gold chains and wife beaters.

Short version: will a 2005 lq4 out of a 2005 2500 HD fit into a 81 camaro without changing the accessory brackets, oilpan, intake etc...

All the accesorys will work accept for ac compressor, which they make a bracket to locate it to the top passanger side of the engine istead of the lower passanger side which would hit the frame. Besides that you need to think about converstion headers which i ordered mine from Schoenfield headers and then mounts. Mounts I used was stock chevy v8 with a conversion mounts from Dirty Dingo. Had problems with those lining up, they sent me the 4x4 mounts which didnt fit, and they finally sent me the 2wd ones after lots of back and forth. Transdapt also make converstion mounts. Running my 92 chevy c1500 on the 2006 Silverado 5.3 using the 5.3 engine alternator, power steering, waterpump. the engine had ac but I just took off the bracket off the block since the scrapyard kept the ac compresser anyways. Also somthing i didnt think about was the oil pan, I would recommend a 5qt conversion pan, I believe holly makes it and do it while the engine is out. My 6qt truck oil pan is the lowest hanging thing on my lowered truck. I will be changing that out before summer, just didnt think about it while it was out and I wish I would have. I works for now and set into place with the truck pan with no clearance issues at all and honestly if it was a 4x4 or not lowered I would think it would never be an issue.

yeah they are if you can weld and honestly when the first ones didnt fit I almost had them fabbed up by someone local but the guy from dirty dingo sent me the right ones finally and it worked great. Just use the stock motor mounts for that car and mount a plate on the 6.0 and start from there. AC wasnt a big loss for me cause the truck didnt have it anyways.

If you havne't yes, register at ls1tech.com (or dont even need to register, really) and look for the hybrid forum. Its all about swapping LSXs into non LSX vehicles. There ought to be a few of these swaps done already.

In general, its easy to make motor mounts, but you might also find it a time saver if there are vehicle specific ones out there that position the motor how it needs to sit for that setup.

The AC compressor is a separate belt and bracket, so you can remove that and pitch it, unless you are wanting to keep AC in the car.

We fit a cummins in a Chevy without and sheet metal modification we should be able to bang this bitch. I spent a bit of time over on the ls1 forum. Lots of good info but I really like to pick your brains oh saviour. I kinda want AC but the headers wont work with it and we would need to relocate the pump.

If you need a new oil pan and pickup, OEM stuff (like a stock LS1 F-body pan) are actually pretty cheap at a dealer, cheaper than aftermarket.

Mucho Dinero on headers, unless you can find manifolds that would fall in with minimum of mods to fit.

It won't be a horsepower monster but would be a solid driver.

I need to build a car next, this 4by stuff is getting old.

If my truck is any indication of how the car will drive I will be very pleased. With minimal modification I am looking at around 450 hp. I found headers for 250 but wont work with AC. I would prefer to find some manifold, I dislike headers.
