Yes that is correct the 2.8 mounts are the correct mounts if you use the motor brackets from summitracing.com or jegs.com. Corvette radiator is actually quite a bit thinner than the camarro. I would stick with the vette. A new one is only around 160 from a radiator shop. Go to and get the JTR manaul. Its worth the money.

I am finishing up on my swap, have to mount the radiator and driverside header and I will be ready for the road. The intake I used is the Edelbrock Multiport fuel Injected system and there is plenty of room for the hood, however to get some cool air in there I will be creating some custom hood vents.

I would get some L-98 corvette heads from a salvage with exhaust manifolds and go with that for the price you are looking for.
LT1 Heads will not work due to the cooling setup..... If you dont mind cast heads the L-31 GM vortec heads are the way for little money. I got a pair new for 500 and sent them to the machine shop to angle cut the valves, port intake, change to better springs and retainers for little money.
Good luck
