rookie LT1 question, I want to mate a auto LT1 to my 4spd, and upgrade to 5spd later

[coyote11]

I have a '67 Firebird with a 326 and a 4 speed, the block pattern is definitely different. I have an opportunity to buy a LT1 from a 94-95 Chevy Caprice police car. I know I would need different motor mounts and such, but can I just get a SBC bell housing and mate it up? Then, will the auto ECM with the motor be capable off running properly with a stick behind it? I will eventually go with a 5 speed stick, but funds are tight. I would stick with the Poncho motor, but the LT1 is super cheap and fuel injected, lighter too.

Any suggestions would be great.
