Will these LT's work?
Will these LT's work? I have the chance to buy a LT1 with Impalla LT headers. Can I get these to work on a 94 Z28?
And other than the heads is there anything else that would keep me from putting this in my car? Is the opti the same?

Good to know.
OP, other than the headers not fitting the body, nothing else will prevent you from using that engine.
There are some differences over the years, but nothing that can't be worked around or changed to use the engine. If you remove your engine and install the new one using your current wire harness and PCM, you should have no issues.
Also the heads performance difference between the iron heads and alum ones are negligible, only notable difference is the weight.

Ok if the heads flow simalar (iron or aluminum) use them untouched, put in a 224/230 LPE cam, 1.6rr, CAI, 3000 stall, delete the cats, add LTs header and full exhaust what would I see at the wheels? I will be adding the NANO and N20 of a 150 shot.
One thing you have to note is that the iron heads have press fit rocker arm studs, so you have to get them pulled and tapped if you want to run any aftermarket ARP rocker arm studs. Also the iron heads might have issues with some springs (I think the valve guide diameter is slightly larger, not sure), you might have to do some research. 96CapriceMgr will know what you can and cannot use.
If I had to guess, I'd say maybe 320 rwhp on motor.

I have 374 aluminum heads on the block out of the Camaro. I will just swap heads, put new head gaskets on the old block along with the iron heads and sell it off. The engine ran fine just blew white smoke every now and then, guessing it would be worth $300.00-$400.00 for a long block with rebuilt heads and the opti. The engine is a 94 with 120K miles.
