So just so I am understanding you correctly, you want to use your intake off of the LT1 onto the 400sbc? I think the older sbc blocks will not work with the newer LT1 heads, (that is if you plan on using the LT1 intake) also the cam driven optispark will be a problem. Older sbc blocks do not have the provisions for knock sensors either. I am sure with some engineering this can be done but it may get expensive. I would suggest you buy a stroker kit for the LT1 and use the existing components. And/or buy an LS1 wiring harness and convert the LT1 over to coil-near plugs with the tuning capability of the OBDII. I am sure this thread will get alot of attention. Last option but my favorite is just swap over to an LS engine. Best of luck to you!

You could go the tuned port route, my brother loves that set-up he builds and tunes them. I think you'd have to use bigger runners for that set up though. Those units can be bought cheap at salvage yards and the harnesses aren't hard to make. TPI setup is great for low end torque as well.
You can use vortec heads as well, just buy the lower vortec tpi plenum. Best part is SBC parts are extremely cheap!
