I have an LT1 block that I want to put a set of Dart Pro 1"s on. I'm way to lazy to mess with the fuel inj. anymore. I know the heads are reverse flow, but what about the block? Isn't it a regular small block chevy with the extra hole for the pump gear? Any knowledge would be appreciated.

 

You are going to have to still do the appropriate changes to the heads to make them work with the lt1 block.
*Oil drain back in the valve spring area
*blocking off the coolant to the intake
and there is a few other little things but I choose to just go aftermarket block instead of use the lt1...
