) I want something I can hop in and simply drive. This swap seems to fit the bill.Oh and for when I need power, I've got a stout dodge with a lot of work (and more to come) done to it. Then there's the sportbikes too....
I'm not looking to build a drag car. I'm looking to make the SS a daily driver with decent power and better handling/braking.
I wasnt saying you had to go wild at all. Just saying that cam in a 6.0 will idle like stock and power will fall off around 5-5200rpm. I had one in a 5.3 and wasn't happy with it. I suppose it would be a great cam for a dd though.

Ok I´m renovating a 86 el camino and using a LM7/4l60e.
Caddy oil pan
sp?? headers
Corvette pully and intake
I got the relocation plates and have still not got them to work.
So I have started to make my own mounts.
As she will not be beaten hard i am going to stick with the 7.5 and put a diff in her.
When I get her home I will re-map her for 98 oktan gas which should give her a good 30hp more.

From what I read the stock LQ4 cam falls off around that area? I'm not picking the LS6 cam, it's just in a motor I'll be looking at this week. He's asking $1300 for it, but I believe I can get him down a little more on the price. I'd assume I have another ~$500 in parts to pick up then. I wouldn't mind a little bump, but I certainly don't want what I have right now.

So I checked out the engine today. It's nice and clean on the outside. But that's about all it is. I'm afraid of all the extra parts I'll need. I've also been talking to someone about a complete firebird with an LT1 that's wrecked for $900. I know that swap would be an almost bolt in. It'd cost a lot less, especially considering I could send off the shell to the scrap yard. I know the power output wouldn't be the same though. Just don't know where to go...
Continue to push forward with the LS swap. Vintage-wise, the LT1 would be good for your Monte, but all sources always suggest the LS platform. You'll be happier with it.
I got a 5.3 & 4L60E for my Monte from a salvage yard for $1000, and it came with EVERYTHING. There are some parts I can't use, like the oil pan and exhaust manifolds, but if you search you'll find more parts that work. I managed to find F-body exhaust manifolds and a Caddy CTS-V oil pan. With 1" set-back adapters, the engine drops in nicely. Yes, you'll have to do a few mods here and there, but it's not THAT bad. Keep it man, there are lots of good folks here with great advice!

Power wise, the LT1 is rated at 285hp just as the 5.3. But while it'll be out, I plan on stuffing a cam in it and doing a little work on the intake. I'd like to have something in the 325hp range, it looks like the LT1 should fit the bill for all that I want.
The ls6 cam needs more compression to work higher in the rpm range. Not that is matters at this point. FYI if I was in your shoes I would part out the f-body to buy yourself a ls based motor. You'll be happier in the end. LT1-4 are all still old school design/performance imo.

I'm not wanting anything I'll have to rev to 6500rpm. The current engine prob makes around 400hp. It's too much for what I want. I don't deny the LS' are nice. But in this instance, it'll be easier and cheaper to get a decent FI'ed engine with the LT1. The 400hp 6.0 would have been nice. But it'd be $1K for the engine at least, then sourcing every other needed part. I'd likely have about $2500 or more in it by then. I could build a heck of an LT1 for that. I'm only looking for 300hp. Anything over is a bonus.
