I guess i need to find a chevelle specific rad to fit.. I got my 77 silverado with a 454 with a big rad. Any parts i can use off it?. Rad is same width but 4 in. taller. Not tryin to sound to cheap but this is a total budget build... Can i use the motor mounts??? Its a 4 door so i'm not throwing money in it yet till i find out how i like it
