I'll definently consider that ^. I'm just gonna see how things work themselve out, because i plan on getting brakes, suspension and wheels before anything. And i can fab most the mounts for the 350, and i guess gas milage isn't my main concern, it's more driveability in town and on the highway, i'm not really into top speed driving in old cars like these (unless i spent alot of money to make sure i was 100% confident in the chassis), i save the 120+ mph speeds for my motorcycle. My friend had a 76 280 and the engine ran real good for a couple months then would need all kinds of work, but that was when we were like 16 so we didn't even know about puting a v8 in... i think a 350 would be a better base to build off. I'll have about 3-4 grand for the engine swap, but what i think i'll do is see if anyone local has a v8 Z that will let me check it out before i make the choice. I love torque in cars, because around here theres alot of mountains and winding roads, and u need torque to pull u in and out of those turns and up hills. I always get ahead of myself when it comes to things like this, but i think this site will help bring me to reality...because today i was looking at turbo setup's on 350's and already started pricing parts for that..lol...i gotta do the basics first...i appreciated all the feedback so far...
