Hello, you'd need to first swap over to Vortec style heads. If this were an obd2 vehicle you could just use 96 up vortec stuff (injectors, ecm etc) but being obd 1 you'd need to go with an Edelbrock Pro-Flo® 2 EFI kit. It has everything you'd need minus the heads.
Just switching over to mpfi would give modest HP gains 25-50 would be a good estimate.
The limiting factor on this motor is the cam and compression ratios.
