I'm in the process of building a traditional gasser as much as I can from this 55 Pontiac that I have. For starters i'm using a 389 Pontiac mill bored to a 400 w/ 670 heads, Th400/2800 stall and 3:73 gears. I picked up a differant frame from a Hamber and got down to work. My old frame needed much more work so I started from scratch. For my axle i'm using a 50 F1 along with a disc brake kit from Speedway. I also got the springs and hangers from there also. The F1 already used a 1 3/4" wide springs so everything matched right up. The track width was very close to the stock front end. Here's the springs mounted in, btw the Hamb is an invaluable source of information for a build like this. Than from there I decided to leave the outer rails on the frame and remove the engine crossmember. And also instead of removing the front radiator crossmember, leave it as it's the mounting point for the front sheetmetal. But since it's doing double duty also to sustain the front suspension I boxed it in with 1/4" plate which also served as a mounting point for the front perches.
