Alright guys, just wondering if you can help me with this. This is my first AMC and I am so glad I kept it in my jeep instead of doing what everyone else does and go for the chevy swap. My question is, how much horsepower can I expect from my 304. Its a '78 bored .030 over edelbrock performer package, cam, intake, 600 carb,all new valves with edelbrock springs and retainers, standard headers, mallory unilite dizzy, msd 6al ing box. Again, this is my first AMC, so I have no Idea and not really sure if I can relate it to a chevy 5.0 litre. Any help would be great. Thanks
