Why not look into swapping in a 5.0 fuel injected. The options are endless, they look nice, and the same mounts, and front suspension can be retained for future, if you change your mind. The chevy LS engine would be great in an old Camaro, but if pushrod V8 is alright, then the 5.0 is the way to go, besides if you want power, either engine makes as much as your wallet allows. A gentleman where I used to live in Bowling Green, had a 5.0 in his 1995 Mustang putting 1300 horsepower down to the pavement when the car would hook up. He had fuel injection with a ported edelbrock intake, Trick Flow heads, and twin turbos. Very cool set-up, and could drive it on the street.
